How to strengthen the shock resistance of powder metallurgy metal parts?
Change the material, or change the shape, then heat treatment, and there's no other way to do it.
Sintering technology should be excellent, if possible, hot isostatic pressing (low pressure) sintering furnace sintering, the stress is small, uniform structure.
The finer the crystal powder, the better the stress after sintering.
Product design, R angle must be greater than 1mm, in principle, the bigger the better.
