【Abstract】 The study of silicon and rare earth elements for the pattem of their influece upon ZA27 regressive designing alloys mechanical properties have been studied with the experimental method of the orthogonal. This study shows that silicon and rare earth elements have a notable influence on the compressive strength and the impact toughness of the alloy, and an optimized ratio in the influence on the systhetic properties.更多还原
