Why is the Ductile Brittle Transition Temperature of many metals are not available ? I was trying to find the DBTT data for silver and was shocked to know the lack of these data.
You may get some information from this thread.

During MD tensile simulation, the stress values rise upto some GPa (high stress value). I think it is because of the following reasons: 1. System is almost defect free or only with few defects...

FCC has 3 fold symmetry but BCT doesn't. So why should we draw a BCT inside a FCC and name it as martensite. A reverse can also be done where we can draw BCT and they get a FCC out of it. If so in...
