Questions
Question (1)
Hi, everyone. Recently, I'm working with Molecular Dynamics simulation with welding materials (but are not limited with welding), and try to validate the model that was made with a good experiment. Would you please share with me some good explanations, references, or tips to start with an experimental work in material science, especially metallurgy? What I know is, most of the experimental work is costly (especially in trial and error steps), thus it would be great for me if you mind to share your experience(s) when you are doing your experiment(s).
Thanks in advance.
