Influence of structural state upon the cavitation erosion of GX5CrNi19-10 austenitic stainless steel subjected to solution treatment

Abstract

The paper continues the previous researches of the authors, on the same topiccavitation erosion- researches which ended with a Ph.D. thesis and through other works. Samples of the austenitic stainless steel GX5CrNi19-10 have been heat treated and tested under cavitation erosion. There have been obtained modifications of the cavitation resistance according to the thermal treatment. By use of structural analyses and micro hardness tests, the influence of microstructure on the steel cavitation resistance was emhasized. The thermal treatment of solution treatment increses cavitational erosion resistance to GX5CrNi19-10 austenitic stainless steel.
