                                                                                                                                    ★合金結(jié)構(gòu)鋼一般分為調(diào)質(zhì)結(jié)構(gòu)鋼和表面硬化結(jié)構(gòu)鋼。                                                                                                                                                                                                                                                                                                                                                                                                ①調(diào)質(zhì)結(jié)構(gòu)鋼                                                                                                                                這類鋼的含碳量一般約為0.25%~0.55%,對于既定截面尺寸的結(jié)構(gòu)件,在調(diào)質(zhì)處理(淬火加回火)時,如果沿截面淬透,則力學(xué)性能良好,如果淬不透,顯微組織中出現(xiàn)有自由鐵素體,則韌性下降。對具有回火脆性傾向的鋼如錳鋼、鉻鋼、鎳鉻鋼等,回火后應(yīng)快冷。這類鋼的淬火臨界直徑,隨晶粒度和合金元素含量的增加而增大,例如,40Cr和35SiMn鋼約為30~40mm,而40CrNiMo和30CrNi2MoV鋼則約為                                                                                                                                60~100mm,常用于制造承受較大載荷的軸、連桿等結(jié)構(gòu)件。                                                                                                                                                                                                                                                                                                                                                                                                ②表面硬化結(jié)構(gòu)鋼                                                                                                                                用以制造表層堅硬耐磨而心部柔韌的零部件,如齒輪、軸等。為使零件心部韌性高,鋼中含碳量應(yīng)低,一般在0.12~0.25%,同時還有適量的合金元素,以保證適宜的淬透性。氮化鋼還需加入易形成氮化物的合金元素(如Al、Cr、Mo等)。滲碳或碳氮共滲鋼,經(jīng)850~950℃滲碳或碳氮共滲后,淬火并在低溫回火(約200℃)狀態(tài)下使用。氮化鋼經(jīng)氮化處理(480~580℃),直接使用,不再經(jīng)淬火與回火處理。
