摘要/Abstract

摘要： 通过Thermecmastor-Z型热模拟机研究了0.75C-0.11V微合金钢双道次压缩试验850～1000 ℃奥氏体区等温变形后道次间隙时间内的软化行为。结果显示，在30%变形量，3s-¹变形速率下，当变形温度≥1000 ℃, 该钢完成再结晶弛豫时间≤100s;变形温度≤880 ℃时，即使弛豫时间延长，再结晶亦难以进行。

关键词: V微合金化高碳钢变形温度静态再结晶

Abstract: The softening behavior of 0.75C-0. 11V microalloy steel isothermal deforming at austenitic area 850～1000 ℃ within interval of passes has been studied by double-pass compression test using Thermecmastor-Z thermal simulation machine.Results indicated that with 30% deformation and 3 s^-1 deforming rate,as deformation temperature ≥1000 ℃, the relaxation time for performing recrystallization was ≤100 s,and as deformation temperature ≤880 ℃,it was diffcult even extending relaxation time to put forward recrystalization of steel.
