Description

technical field [0001] The invention relates to the field of alloy technology, in particular to a high-temperature-resistant aluminum alloy material and a preparation method thereof. Background technique [0002] The amount of aluminum alloy is second only to steel materials, and it is widely used in aerospace, automobile, navigation, chemical industry and other fields. In the field of automobiles, automobile lightweight is the future development trend. Aluminum and aluminum alloys are the preferred materials for this purpose. But in the operation of the vehicle, many components are running at high temperature, such as the engine, piston and other components of the car, the operating temperature range is between 300 and 400 ° C, so it is necessary to consider the temperature of the components in this temperature range Mechanical strength, as we all know, with the increase of temperature, the grain will continue to grow and reduce the tensile strength. According to the Hall-B...
