Lowering the cooling rate leads to the decrease of the plasticity, fracture toughness and corrosion resisence of the back material, mainly due to the increase of twin martensites(including those existing in lathmartensites) after quehching.
降低淬火冷却速率，使背部材料塑性以及抗疲劳性能有一定的下降，这主要是由于淬火后孪晶马氏体（含板条内微孪晶马氏体）量有所增加，回火后，使孪晶马氏体发生退化产生脆性片状碳化物，进一步增加了回火脆
The main cause of low impact toughness is that following the long cooling time, the structure becomes coarsing and appears corse-grained twin-mastensite.
冷却时间长,显微组织粗化,出现粗大孪晶马氏体,这是影响韧性低的主要原因。
