Reddit for Materials Science and Engineering topics
Materials science - an interdisciplinary field applying the properties of matter to various areas of science and engineering. This scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on nanoscience and nanotechnology in recent years, materials science has been propelled to the forefront at many universities. It is also an important part of forensic engineering and failure analysis. Materials science also deals with fundamental properties and characteristics of materials.

Im starting a masters in mat sci/eng and am struggling with the pace of the course and all the new concepts being throw at me. Even the concepts I wouldve been familiar with from my undergrad seem to be 10x tougher.
Honestly wondering what the end result of a postgrad looks like, is it worth delving this deep into the field? do you actually use these concepts in the real world or am I learning them for an exam?
Wondering if like cast iron, aluminum can break (crack) due to brittleness..
Specifically, thinking of cast aluminium casserole dishes, if I were to drop it accidentally, would it dent or crumble like cast iron?
I am new to this field as a PhD student. I am having a hard time learning from the books because for some reasons, most of the books I came across don't really have any problem sets. I like problem sets because they introduce you to the different ways you can apply the concept you learned. Do you know any books for someone who wants to get advanced in the area of material science that has strong problem sets?
Hello everyone. I am an international student and have completed masters in materials science and yet am unable to find a job in USA. I have prior experience as a process engineer via co-op in a company which is listed on NASDAQ. I have recently been applying for every opening on linkedin which meets my qualifications but still have not received any positive reply. If someone could guide me on how to proceed further i would be grateful. As if i don’t find a job soon (10-15 days) i may have to go back from USA as my EAD mandates me to either find a job or go back to my country. I also have experience as a graduate research assistant under my college lab. Please help me on what can better my prospects. Thanking you for your time and patience in advance. Please help me out as i cannot afford to go back.
For gunmaking, I was imagining an M1 Garand made out of Chrome-plated Copper, being lighter, yet still as versatile as forged steel, is this correct?
I decided to study undergrad in chemistry back in school since I was pretty good at it. Knew I did not want to be a doctor or an engineer. However, down the line I realised that it isn't a very fruitful path and I don't enjoy chemistry like I used to especially after I had to study a shit ton of Quantum Mechanics. I did an internship regarding GO and rGO synthesis and its at a research lab in India, and I decided that I need to try an MS in materials science since I truly loved it. How different will it be? Also do I have a good shot at colleges like NTU, NUS etc?
What machine part would u guys recommend where it would get me a good grade plus impress my professors.
Howdy howdy,
So im conducting a materials study (small scale high school research project) and was wondering if the size of sample matters.
Im researching concrete and its tensile strength and plan to use a hydraulic press to test rectangle plates of it and compare my modified formula to standard quikcrete.
Does it matter if the sample size is 3x3x1 inchs instead of 9x9x3 inchs (conforms to ASTM Standard C78 ratio 1/3 for tensile testing of concrete)? This would use less material and make creating the molds much easier for producing the samples on scale, also I don't know how big of a press ill have access too...
TLDR: For a compare/contrast materials study as long as the sample size (Dimensions) is the same does it matter how big it is
I’m about to apply for uni and my top choice is Oxford for an MEng in materials science. All my other choices are currently maths and physics. I’m just wondering if materials science is more versatile than maths and physics and if it’s worths doing materials science everywhere else. I’m tempted to try a career in finance and would this be possible with a matsci degree? Basically in summary, is materials a worth it degree and are my opportunities for success good?
anyone know where to lookup for solution for this?, looking up to check answers is really troubling
Will this be the year of Nobel prize for scientists working on Metal Organic Frameworks.
IMO, If there is a thing called 'wonder material', then MOFs are THE one.
I'm sintering some Mo pellets made by pressing pure Mo powder (10 - 20 um, or, 325 mesh size range), placing them in MgO crucibles, and into a rapid heating furnace (100 C/min till 1800 C). Sintering atmosphere is argon, and I pump down to rough vacuum (5 mTorr) twice with subsequent Ar backfills. The bottom side of the pellet is in direct contact with the crucible. After heating, the walls of the crucible are blackened a with layer of blue-ish/black deposition, and the area around the pellet has a 'ring' of black and greenish yellow deposition. I also notice some deposition on a glass viewport directly above the object being heated.
I do not think the Mo is reacting with MgO as the coating is on the walls of the crucible which are a ways from the pellet. The area of the crucible directly under the pellet remains white, leading me to believe the contamination is coming from the powder. My best guess is MoO3 or MoO2 vaporization, but it's surprising to see that amount of native oxide contamination. I have also SPS'd Mo pellets using the same powder, and do not notice any discernible oxide contamination through XRD/SEM-EDS, so I'm pretty stumped.
Anyone dealt with this before and know what could be causing it? Any potential solutions (Ar+H2 pretreatment or similar)?
Hi I’m an international student and I’m 17 applying for undergrad in materials science and various universities.
I wrote about half metals in my personal statement and I just want someone to please take a look and point out any factual errors or just review it in general.
I’ll be super grateful.
Hello everyone! I am currently performing research with Additive Manufacturing working with Ti and Nb alloys, I was wondering if there are any specific books for these two alloys. Thanks!!!
It seems that fermenting seeds to create a leather-like material hasn’t been explored as much as methods like using mycelium or SCOBY. I’m considering experimenting with flax, sunflower, or pumpkin seeds, based on the idea that seeds contain oils, proteins, and fibers that could be activated through fermentation or other processes. The surface may not immediately resemble leather and could require some post-processing.
I’m a complete beginner. Is this idea even feasible? How should I start? What’s the best way to run proper experiments? What kind of scientific knowledge do I need? How do I test the results? I’m feeling a bit lost and would really appreciate your help :)
Our professor provided this graph, where temperature is on the x-axis and the intensity of released energy is on the y-axis. Now, we're asked to draw the same graph for two materials, A and B, with A having a lower grain size than B, while keeping everything else the same. How would I go about drawing that?
Firstly, I have no idea if this is even the right subreddit. I cut open a used water filter from my camper, and found this thing inside. According to the Amazon listing, it is made of solid carbon, with no further details. Question 1: Judging by the provided (admittedly poor quality) pictures, what form of carbon is this? Question 2: Is this even carbon? Or is it something else Question 3: If this is carbon, what can I do with it. Additional information: Right now, weight cannot be properly determined, because it is saturated with water. It feels similar to wood, or a crumbly plastic and rubbing the coarse surface on the end causes it to lose some little pieces, bigger than particals of dust but smaller than grains of sand Judging by some of the details on the domed end, it appears to be preessed into this shape
So I’m doing a project for my work where we need to come up with an engineering product. I wanted to make a colour-changing hoodie that reacts to water, more specifically a horror-style hoodie, where it turns from black to red when wet. Im aware of hydrochromic inks, but I was wondering if there were different ways. Thank you.
I’ve devised, what I believe to be, the first actionable process to create the world’s first “metamaterial”. Reddit won’t let me upload the PDF. I have it saved as. Please contact me if interested. Serious scientists, and researchers only, please.
Hi, i need some values of the maximum stresses for carbon fibre and fibreglass in epoxi resin but i don't know where to look for references
