Abstract

The invention discloses an insoluble metal-reinforced aluminum alloy material for a piston. Added insoluble metals comprise combination of a few of titanium, zirconium, vanadium, tungsten, molybdenum, niobium and tantalum. According to the insoluble metal-reinforced aluminum alloy material, one or combination of insoluble metal elements, including tungsten, molybdenum, niobium and tantalum, in aluminum alloy is added to piston alloy. The problem that with an existing piston alloy material, a piston cannot work in the environment of relatively high engine temperature and explosion pressure is solved; the high-temperature strength is obviously improved; and the requirements of an engine on the piston material for upgrading and updating can be met.

Description

technical field [0001] The invention belongs to the field of metal materials and provides a refractory metal reinforced aluminum alloy material for pistons. Background technique [0002] At present, the engines for trucks, construction machinery, railway locomotives and ships are all developing towards high power and high load, the degree of strengthening is constantly increasing, and the emission requirements are becoming more and more stringent. At present, various piston companies are independently developing new piston materials. The main work is to increase the content of nickel and copper on the basis of aluminum-silicon alloys, in order to expect more alloy phases to appear in the piston tissue, and improve the high temperature resistance of piston materials through alloy phases. Performance, while titanium, zirconium, and vanadium mainly refine the piston structure and also have a strengthening effect. However, the current alloying determines the high-temperature st...
