Abstract

The invention discloses a high-strength heatproof aluminum alloy material and a preparation method thereof. The high-strength heatproof aluminum alloy material comprises the following components in percentage by weight: 1.0-10.0 percent of Cu, 0.05-1.5 percent of Mn, 0.01-0.5 percent of Cd, 0.01-0.5 percent of Ti, 0.01-0.2 percent of B, 0.01-1.0 percent of Zr, 0.001-0.1 percent of Be, 0.01-1.0 percent of Ni, 0.05-5 percent of RE, and the balance of AI. In the invention, the theory of high-quality melts, solid solutions and phase diagrams is used as guidance, and a formula of main alloy elements Cu and Mn and RE is preferentially selected to reduce the temperature range of an alloy quasi-solid phrase and solve the problems of large heat crack tendency during, low high-temperature strength of products and the like; and a formula of low-cost multiple microalloying element is preferentially selected to create substance basic conditions for the cultivation and grain refining action of a high-temperature phase and a strengthening phase in the solid solutions, and finally, the high-strength heatproof aluminum alloy material is prepared.

Description

technical field

[0001] The invention relates to an aluminum alloy material and a preparation method thereof, in particular to an aluminum alloy material containing microalloying elements and rare earth elements and a preparation method thereof. Background technique

[0002] Aluminum alloy is a relatively young metal material, which only began to be used industrially in the early 20th century. During World War II, aluminum was mainly used in the manufacture of military aircraft. After the war, due to the sharp decrease in the demand for aluminum in the military industry, the aluminum industry began to develop civilian aluminum alloys, expanding its application scope from the aviation industry to the construction industry, container packaging industry, transportation industry, electric power and electronics industry, Various sectors of the national economy such as machinery manufacturing and petrochemicals are applied to people's daily lives. At present, aluminum is used in ...
