摘要

利用自行设计装置进行1Cr18Ni9Ti不锈钢的半固态流变浆料制备和半固态流变浆料的直接轧制试验过程。结果表明:在本试验条件下制备1cr18Ni9Ti不锈钢半固态流变组织中先结晶的奥氏体呈近球状

尺寸在100～200μm

半固态流变浆料的固相率为50％～60％;该流变浆料具有较好的流动性

在半固态直接轧制成形过程中会产生液相偏析和一定程度的固相颗粒的塑性变形。

Abstract

This paper describes experiments of preparation and directly rolling of semisolid rheological slurry of 1Cr18Ni9Ti stainless steel on the self- designed electromagnetic stirring equipment of rheological steel slurry. Results show that solid particles of the primary austensite in 1Cr18Ni9Ti stainless steel rheological slurry prepared by the experiment have near-sphere shape and its size is between 100 /nm and 200 /Mm

the volume solid fraction of the rheological slurry is 50% - 60% . This rheological slurry have good fluidity. The segregation of liquid phase in the the slurry and plastic deformation of some solid particles in the slurry occur during semisolid rolling.
