Abstract

The invention discloses an automotive engine piston made of a novel material and belongs to the field of automotive engine components. The novel material is rapid set high-silicon aluminum alloy, a certain novel tissue structure characteristic, namely ultra-fine microstructure is obtained through the rapid set technique, the solid solubility limit of the alloy is improved, the heights of components are even, segregation is nearly or completely avoided, a novel metastable phase is formed, and defect density is improved. The material has the advantages of being light, high in strength, high in corrosion resistance and heat resistance, low in thermal expansivity and the like, the solid solubility of Si in an aluminum matrix can be improved, grains are refined, the material is well matched with the matrix, and the performance of the alloy is improved remarkably.

Description

technical field [0001] The invention discloses an automobile engine piston of a novel material, which belongs to the field of automobile engine components. Background technique [0002] Automobile is one of the most important means of transportation in today's society, and it is also one of the pillar industries of our country. Therefore, the research and development of high-performance automotive materials has become an important topic for the development of my country's automotive industry. In particular, key parts and components, such as engine pistons, were usually made of iron alloys such as cast iron and sintered steel in the past, which increased the weight of the vehicle, increased fuel consumption, high driving resistance, low engine efficiency, and brought environmental problems such as pollution and noise. , affecting the development of automobiles. Therefore, in order to solve the above problems, the present invention discloses an automobile engine piston of a ...
