|Abstract||A precipitation hardening (PH) stainless steel was strengthened by laser solution-aging treatment for investigating the strengthening mechanisms and performances. The results show that, hardened layers with mm level thickness can be obtained by laser solution-aging treatment on 17-4 PH substrate. TEM observation displays that the E-Cu particles are in the size of 2-5nm and disperse homogeneously in the martensite matrix. The average hardness of the laser hardened composite layer is 423.6 HV which is about 36.6% higher than the substrate. The analysis indicates that the improvements on microhardness can be mainly attributed to the dispersion strengthening of E-Cu precipitate phases. For 4.5 h cavitation erosion tests, the cumulative volume loss of laser hardened sample is only approximate to 45% of the substrate, which shows well prospect for application.|
