摘要：

In iron alloys surface melted by power laser treatments, thin, relatively soft layers mainly constituted by austenite, can form in the upper part of the solid state transformed regions. The mechanism of formation involves both carbon diffusion from the melt, in amounts sufficient to stabilize austenite, and the high thermal gradients typically produced in the alloys by high-energy sources.
