Effect of Solution Treatment Temperature upon the Cavitation Erosion Resistance of X5CrNi18-10 Stainless Steel

Abstract:

The specimens subjected to cavitation erosion were quenched from different temperatures (1000^°C, 1050^°C and 1100^°C) but maintained the same time (25 min.) at the high temperature. The cavitation tests were made in the T2 device of the Timisoara Polytechnic University Cavitation Laboratory. This device respects integrally the recommendation of the ASTM G32-2010 Standard. The specimens microstructure and the area subjected to cavitation were examined with optic and SEM microcopies and hardness measurements. The differences arising on cavitation erosion resistance are explained through modifications of the crystalline grains dimensions, the chromium carbides proportion and some intermetallic phases not dissolved in austenite and of resistance to plastic deformation.Keywords: stainless steel, heat treatment, cavitation erosion
