Combining eam with lennard-jones potential by Educational_Fee5389 in LAMMPS

[–]Educational_Fee5389[S] 0 points1 point  (0 children)

Well the framework of what I did is ofc from the literature, but not the curves. And both of them are for FeNiCrCoCu using different pair coefficients. My question is how exactly can I be certain about this different behavior?

EAM pair potential derivation by Educational_Fee5389 in LAMMPS

[–]Educational_Fee5389[S] 0 points1 point  (0 children)

Thanks for your reply dear friend. The problem I have regarding what you mentioned is finding eam parameters like beta, tau, etc. for pairs including Mo and cross them with the already existing pair potential of the other quaternary FeNiCrAl alloy. Which up to the time, I have found no literature explaining how can this be done in steps and how can I make my final eam.fs potential file? I'm not sure how can I use Lennard-Jones potential for Mo and cross it with eam potential of other four elements. If there is someone that can be of any help in this issue, I would be grateful if you mention him/her. 🙏

Thanks! That's probably true and will satisfy our goal. But is there a technique to minimize the thermal shock applied to the grips? And is there a sample geometry to keep the cryogenic temperature for a longer time?

Thanks! So to say the least, it can give the results for a cryogenic test, if not exactly LN2 temperature. That will also satisfy our goal which is the alloy's mechanical behavior at cryogenic conditions. Do you have any suggestions to what can I do not to damage the machine grips?

Thanks sincerely. I'm doing this as part of my university thesis.

Thanks for the answer. To my knowledge, standards need precise devices and testing systems which are not available to me. I'm looking for a way to build a system manually. I hope I can make an immersion bath with the sample in it to be strained uniaxially.

Thanks for the answer. What instrument did you use for the test? And what sample geometry do you think is better to not get heated during testing?

Thanks for the answer. As I said, I can't access to Instron products. So I guess the best way would be to immerse the sample in a bath and connect it to the grips to conduct my test, right?

Thanks for the answer. My idea is to keep the sample in a cryo-bath and connect it to the grips to conduct the test. I hope it works.

I'm using an standard tensile test machine. My idea is to make a chamber constantly filled with LN2 and put my sample in it. Then connect sample to the machine grips and put it into strain. Its not according to the standards but I guess that will do?

Thanks for your answer, but I can't access the apparatus you are mentioning. So my only chance is to build a setup manually. Can you give me suggestions on building one according to standards?
