摘要
设计与开发了四种成分的新型相间沉淀钢，其σｓ＞５００ＭＰａ，室温ＣＶＮ＞１７０Ｊ，截面尺寸在１５０ｍｍ范围内可获得均匀的组织与性能，可直接在轧制或正火态下应用。
A new type of interphase precipitation steel has been developed.On the basis of Fe-1V-0.2C alloy by adding 0.5Al alone and 1.5Mn-0.5Al or 1.5Mn-1. 0Si complex,its CCT dia-gram displaces to shorter time and higher temperature. The steel has the following mechani-cal properties in air cooling:σs>500 Mpa,room charpy value>170 J,and the uniform struc-ture and properties can be achieved up to 150 mm in diameter/thickness,Compared with lowcarbon bainitic steel,it has much higher toughness.Thus,it is expected to be used directly inas-rolled or normalized.
