The influence of chemical composition and heat-treatment on the microstructure and mechanical properties of the steel is investigated.
研究了化学成份和热处理工艺对钢板力学性能和微观组织的影响规律。

Test shows that the depth of residual compressive after chemicalheattreatment is correspondent with that of diffusion layer.
试验表明，化学热处理后残余压应力的深度往往与渗层深度相一致。
