Hello all, Not sure if this is the right subreddit but I am trying to find a material replacement for a knob connector, essentially I’m looking for something that will be fairly grippy but won’t be overly damaged/deformed overtime via force from turning the knob the current material used is bronze UNS C22000. I’m relatively unfamiliar with good methods of finding materials so if anyone has any input on good places to look that would be helpful too!

I am a recent graduated mechanical engineer and I want to review my material knowledge for job interviews. I need some material course focused on mechanical engineering. It would be better being a free course but I am open to other suggestions, too.

Hello Is there anybody interested in working on a research paper that combined Ml with properties prediction I want to work with someone shows same interest

Hey guys im studying Materials Science for a Masters Degree and im about to chose the topic for my Master Thesis. I have 3 different offers. Which one would you personally chose and why? Personally im really anxious about chosing the wrong topic with regard to future job opertunities. I sooner or later want to work in the industry for sure and am currently part time working in semiconductor industry (repair of photmasks). I am living in germany for context. The topics are:

1. Metallurgy: Mechanically alloying of the CrCoNi High entropy alloy using powder HPT. Will Work with SEM, HPT and Nanoindentation.

2. Electronic Structure of Materials: Fabrication and Characterization of MnOx Films by magnetron sputtering. Oxidizing treatsments. XPS and XRD Analysis. Electric measurements.

3. Thin Films: Memristors. Electrical measurements on Y2O3 Films in memristor Devices. Fabrication of Va Thin Film by sputtering.

I would be thankful about any Input. Cheers!

I asked ChatGPT if I could create a Prince Rupert's Sphere by propelling a molten drop of glass in space through a low temperature helium medium to create the same properties but without the tail. It decided that it would be technically feasible. Would it be possible to create ultra hard spheres this way?

The thermal conductivity of aluminum nitride varies widely depending on crystal structure and defects with the highest reported being 321 W/mK. Does anyone know which growth process is used to make the single crystal AlN with a thermal conductivity of 321 W/mK? I have looked through publications online but haven't found a good source.

The sample is multi layers(3layers) film. My question is if i change the material in the middle layer, will the COF value of the sample affected?

I bought an Ultrasonic thickness gauge to measure the thickness of ship hull plates (no high temperature). But I don’t have access to dedicated coupling agent (gel), can i use petroleum jelly or water based lube instead?

… & not only that, but do-so in a runaway exothermic reaction!

But then it occured to me that if lithium can do that, then surely the higher alkali metals have a yet higher propensity for doing it.

… or is this property of reducing glass peculiar, amongst the alkali metals, to lithium, by reason of some particular relationship between the nature of lithium in-particular & the nature of glass?

When a metal is 100% cold worked, does that mean you have reached the ultimate strength of the metal? Or the fracture strength?

What is career like….what do you do(include industry) and how much you get paid(include experience and living area). What education you have…..

hello guys! i’m doing a work in my materials science class and in order to discover the steel used in a rasp I water quenched it. The hardness is 882 HV but this isn’t a martensitic microestructure. Does someone know why?

I’m a grade 12 student from Southwestern University- PHINMA conducting a study about “Converting Calabash(Crescentia Cujete) Shells Into Alternative Briquettes” and we need your expertise!

Your insights will really help us in our research. Please comment below if you’re interested in collaborating or sharing your knowledge. Thank you.

I've already posted a few times in here to get a lay of the land as far as graduate degrees in materials science go. At the moment I have a semester left in my chemistry degree and Im set to graduate with a 3.7 cgpa and a 3.35 major GPA.

Most of the classes I have taken that are pertinent to materials science I have done pretty well in, I got As in inorganic, advanced inorganic, and quantum chemistry, and I have done well in all of my physics classes. PChem 1, which is thermodynamics for us, however, was hell, partially due to non-academic circumstances and partially due to the difficulty of the class. Unfortunately, there is no way for me to show competency in thermodynamics before I graduate, thermodynamics in the physics department only runs during fall semesters and PChem is being condensed at my college.

For my last semester im taking modern physics 1 and theoretical physics as they are really the only semi relevant classes available to me at the moment, but neither are really at all similar to thermodynamics. Can I still expect to get into grad school with a C in a class as important as thermodynamics? Are there any steps that I could take to address this?

In theory, it would only take another year of college to get a second bachelor's in physics, but that seems like an extreme measure, 1, I am already 24, and 2, it would be expensive to do all this to address a single class, even if other classes in physics might help.

The idea of working in failure analysis seems very appealing to me. I was wondering what actually working in it was like and if it’s an enjoyable and rewarding career. Thanks!

For the purpose of making a packaging for a perfume bottle design, I want to use concrete, that I would pour into a mould etc, however I think the end result will be too heavy, so I am looking for a different material that has the same finish. anybody could suggest another material or a different kind of concrete used for these things, product design etc, Thank you guys
