LASER SURFACE MELTING OF GCr15 BEARING STEEL
|
Abstract:
The microstructure of GCrl5 steel surface melted by laser has been investi-gated.The strengthening mechanisms of surface melting are discussed.It shows that thestrengthening mechanisms of surface melting are the twinning strengthening of martensite,the deformation strengthening of retained austenite,the carbon solution strengthening andthe cellular dendrite refining strengthenting.
