摘要：The effects of Co element on the microstructure of precipitation hardening stainless steel was investigated by metallographic microscope (OM), transmission electron microscopy (TEM) and X-ray diffractometry (XRD), and the mechanical properties were measured by tensile, hardness and impact tests. The results show that with increasing Co content, the volume fraction of reversion austenite is incread. The precipitation of ε-Cu pha is remarkably decread, leading to the improvement of ductility, while the strength and hardness are decread. Co element improves the strength and toughn
freedomess of stainless steel through fine-grain strengthening, solution strengthening and austenitic toughening.
