氧化物冶金技术及其发展展望
Oxide Metallurgy Technology and Its Development Prospect
摘要
Abstract
Oxide metallurgy technique is a new technique for the refinement of grain size by using small nonmetallic inclusions in steel to induce the nucleation of ferrite,the high performance steel with high strength,high toughness and good welding performance can be obtained by using this technology.However,the current research results on the mechanism of the nucleation mechanism of the crystal is not unified,and there are unexplained counterexamples in each nucleation mechanism.This paper introduces the research background of the oxide metallurgy technology,and describes the microstructure characteristics of the ferrite,summarizes the types and characteristics of inclusion which could induce the nucleation of ferrite,and analyzes the crystallographic features of intragranular ferrite,and points out the problems of oxide metallurgy which need to be solved.关键词
