摘要
对铁素体加球状渗碳体 T10工具钢进行了激光处理。透射电镜观察发现激光处理区中存在微晶及非晶组织,经鉴定微晶组织为奥氏体、微晶奥氏体与非晶组织混合在一起,其形成与球状渗碳体的存在有关。
T10 steel with a starting structure of ferrite and spheroidal cementite wasimployed to undergo laser processing.Microstructure in the laser-processed zone was in-vestigated by means of TEM.Both microcrystal and amorphous phases were found in thelaser-processed zone.The former was identified to be austenite mixing with the amorphousphase.The formation of the amorphous is attributable to the existence of the spheroidalcementite.
