Promising methods for strengthening piston aluminum alloys of heat engines

Abstract

Due to the increase in the specific power of heat engines, one of the most pressing problems of modern engineering is the increase in the contact strength and heat resistance of piston aluminum alloys. The article considers the main promising methods of strengthening piston aluminum alloys in the aspect of modern technologies. Long-term operation of heat engines in operating conditions close to critical conditions contributes to melting of the grain boundaries of piston alloys, which negatively affects the reliability of internal combustion engines. In General, the task of increasing the heat resistance of piston aluminum alloys is one of the main tasks of modern engineering.
