摘要
本文采用逐次抛光法考查了一种中碳合金钢在300℃等温条件下所获得的V型下贝氏体(B_L)的空间形态。应用这种方法能获得B_L的三维生长信息,并有可能比较B_L生长的扩散机制和切变机制。
The 3-dimensional morphology of a V-type lower bainite(B_L) formed in a medium carbon alloy steel under isothermat treatment at 300℃ has been investigated by step-by-step polising technigue. The use of this technique enables the 3 dimensional growth of B_L to be obtained. Consequently it is possible to make a comparison between the diffusion mechanism and the shear mechanism for B_L growth.
