Abstract

The kinetics of the growth of M₂₃C₆ carbide particles in 9% Cr martensitic steel with a high boron content is studied under conditions of long-term aging and creep. It is shown that the grain-boundary diffusion is a mechanism that controls the coarsening of these carbides during the aging. Deformation accelerates the coarsening of particles during creep, which can be explained by additional diffusion along dislocation lines.

变形在9％Cr钢中粗化M 23 C 6碳化物颗粒中的作用

摘要

在长期时效和蠕变条件下，研究了硼含量高的9％Cr马氏体钢中M ₂₃ C ₆碳化物颗粒的生长动力学。结果表明，晶界扩散是一种控制时效过程中碳化物粗化的机制。变形会加速蠕变过程中颗粒的粗化，这可以通过沿位错线的附加扩散来解释。
