Effect of laser surface remelting on the fatigue crack propagation rate of 40Cr steel

In the present work, quenched and tempered 40Cr steel was treated by laser surface remelting, followed by microstructure evolution, hardness, residual stress field and external morphology investigation to understand the effect of laser surface remelting on surface characteristics, as well as the gra...
