Abstract

The invention provides a high-performance eutectic aluminum silicon alloy piston material of a vehicle engine. On the basis of ZL109 alloy, the novel eutectic alloy material with high strength and low thermal expansion coefficient can be prepared by adjusting the alloy composition and adding trace elements such as V, Zr and P. The eutectic aluminum silicon alloy has the characteristics of being excellent in high-temperature property, high in hardness, low in thermal expansion coefficient, good in wear resistance and the like, thus being better in accordance with the requirements of the high-performance vehicle engine.

Description

technical field [0001] The invention belongs to the field of nonferrous metal material preparation technology and metamorphic treatment technology, and specifically relates to a high-performance vehicle engine eutectic aluminum-silicon alloy piston material. Background technique [0002] The piston is the heart of the engine, it bears alternating mechanical and thermal loads, and is one of the key components in the engine with the worst working conditions. Working at high temperature, high pressure and high speed determines the working efficiency of the engine, so the piston alloy is required to have better volume stability and higher high temperature strength. The continuous improvement of engine performance has led to a significant increase in the working load of the piston, thus putting forward higher requirements on the performance of the piston, especially the high temperature performance, and the piston material is the first to bear the brunt. [0003] At present, tra...
