Abstract:Ni─Co alloys have attracted extensive attention from materials researchers in recent years because of their excellent properties. The effect of solute segregation on the properties of the alloy is studied by molecular dynamics simulation. The results show that the yield strength increases from 2.8 to 3.5 GPa when the solute atom Cr is introduced into the grain boundary. Under the action of stress, the disorder of segregation grain boundary is enhanced, which hinders the growth of grain, produces less layer fau… Show more
