Residual stress field of HIPed silicon nitride rolling elements [PDF]
, 2002 The residual stress field of HIPed Si3N4 rolling elements were studied. Two kinds of HIPed Si3N4 ball blanks self-finished at different nominal lapping loads ranging from 1.3 to 10.87 kgf/ball and four kinds of commercially finished 1/2 in (12.7 mm ...

Investigation on Residual Stress Loss during Laser Peen Texturing of 316L Stainless Steel
Applied Sciences, 2019 Laser peen texturing (LPT) is a novelty way of surface texturing based on laser shock processing. One of the most important benefits of LPT is that it can not only fabricate surface textures but also induce residual compressive stress for the target ...
