Fe-Mn-Si-Cr形状记忆合金0Mn25Cr7Si6Cu抗冲蚀性能因诱发的密排六方ε马氏体局域弹性he高而优于除高铬铸铁以外的所有其它实验材料. 关键词 ： 抗冲蚀性能,  不锈钢,  Fe-Mn-Si-Cr形状记忆合     Abstract：Erosion resistance of 6 austenitic ferrous alloys has been investigated by comparison with a high chromium iron and 0Cr13Ni5Mo stainless steel used for hydraulic turbine using a rotating disc rig. Based on SEM observations of eroded surface and X-ray diffraction examinations of microstructure as well as simulative measurements of plough-cutting resistant capacity Wp and localized surface layer elasticity he for tested alloys, an attempt has been made to discuss the influence of hardness as well as the capacity Wp, the elasticity he and phase transformation on the resistance of the alloys. The results show micro-failure mechanism is plough-cutting of sand particles in the erosion process. The capacity Wp and the elasticity he are predominant factors characterizing the resistance of the stainless steels and Fe-Mn-Si-Cr shape memory alloys, and there exists a good quantitative formula indicating correlation of the elasticity he and the capacity Wp with their erosion rate Re. The role of phase transformation in the resistance depends on the synthetic effect of the capacity Wp and the elasticity he of induced martensite, and the resistance of 0Mn25Cr7Si6Cu Fe-Mn-Si-Cr shape memory alloy is better than that of the other tested alloys except the high chromium iron because the value of he of induced hexagonal closed-packed martensite is larger.
