Improving residual stresses in DMLS/SLM AM components?

06 June 2016 1 657 Report

Using techniques like laser shock peening and particle shot peening, residual stresses at the surface can be taken care of. But how is it possible to cure internal residual stresses within core of components?

Yunus Kayacan

I think, All peening method operates for getting compressive residual stresses, not removing.

Also You could check normalising anneals, If you need little amount of residual stress in the inner part.

Have a good work.
