The behavior to cavitation erosion of CuSn12-C bronze structures, as obtained by in-depth heat treatments
Autor: L. D. Pirvulescu, C. L. Salcianu, M O Popoviciu, Ilare Bordeasu, I Lazar, Ion Mitelea
Publikováno v: Journal of Physics: Conference Series. 1781:012005
CuSn bronze alloys are some of the most used in the casting of freshwater ship propellers. Through in-depth heat treatments, the microstructure and hardness are substantially altered when compared with the initial state of the material after casting.
