一、引言本文所指的高锰钢是指含锰(wt)13%左右、含碳(wt)1.3%左右的被称之谓“哈德菲尔德钢”的一种高锰奥氏体钢。此钢自1882年由英国人R·A·Hadfield发明以来,以其优异的冲击韧性和较高的强度、在受冲击载荷时迅速硬化使钢具有良好的耐磨性以及无磁性等独特的性能,在冶金、矿山、铁路、电气工程、军事工业和农机制造中获得非常广泛的应用而著称于世.近百年来,围绕钢种的合金成分、性能和制造工艺等问题,人们进行了大量的试验研究,发表过大量的论文和报告。由于试验条件的限制,对
I. INTRODUCTION The high manganese steel referred to herein refers to a kind of high manganese austenitic steel called “Hadfield steel” which is about 13% manganese (wt) and about 1.3% carbon (wt). Since its invention by British RA Hadfield in 1882, this steel, with its excellent impact toughness and high strength, rapidly hardened upon impact loading, gives the steel a unique combination of good wear resistance and non-magnetic properties , Is well-known for its wide range of applications in metallurgy, mining, railroads, electrical engineering, military industry and agricultural machinery.For nearly a century the problems of alloy composition, properties and manufacturing processes for steel have been extensively studied Experimental research, published a large number of papers and reports. Due to the limitations of the test conditions, right
