摘要
目前,对316LN不锈钢在低速率应变下的热变形行为研究很少。本文选用工业316LN不锈钢,通过Gleeble-3800热模拟试验机进行了600^(-1) 100℃温度下,应变速率为3×10^(-3) s^(-1)的热压缩试验,得到了真应力-应变曲线。通过分析真应力-应变曲线和试样的微观组织,得到了如下结论:1 000℃和稍高温度是适于低速率应变下316LN不锈钢加工的温度。
The study on hot deformation behavior of 316LN stainless steel at low-rate strain is very seldom at present. By sam-pling from industrial 316LN stainless steel and carrying out a compression heat deformation test by means of a Gleeble-3800 thermal simulation testing machine at a strain rate of 3×10^-3s^-1 and a deformation temperature of 600 - 1 100℃, true stress- strain curves are obtained. By analyzing the true stress-strain curves and microscopic structure of the samples, it can be conclu-ded that 1 000℃ and slightly higher temperature are suitable for low-rate strain processing of 316LN stainless steel.
