【摘要】 <正> 1前言强化渗氮过程,一直是热处理工作者十分关注的问题。本文着眼于渗氮过程中组织应力和浓度梯度应力的产生、变化及作用。通过对渗层加载时效的试验,证明了渗氮应力在渗氮过程中起着同外加应力一样的作用。无疑,这对强化渗氮过程提供了一更多还原

【Abstract】 This paper deals with an inverstigation on the precipitating be-haviour of γ’ phase and the accelerating diffusion at a low temperaturewhen the nitrided specimens are loaded-age at 280℃,the results show that ni-triding stress plays an important role in the nitriding process.更多还原
