C modified W-RE high-strength heat resistant aluminum alloy material and preparation method thereof

The invention discloses a high-strength heat resistant aluminum alloy material and a preparation method thereof. The 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, 0.0001-0.15 percent of C, 0.01-1.0 percent of Zr, 0.01-1.0 percent of W, 0.05-0.5 percent of RE and the balance of Al. In the invention, high-quality melts, solid solutions and a phase diagram theory are used as a guide, and the C element is used as a high-efficiency modifying agent; the alloy quasi solid-phase temperature range is reduced through optimizing the formulas of main alloy elements of Cu, Mn and RE so as to solve the problems of large heat tearing tendency, low high-temperature strength of products, and the like; and a low-cost multielement microalloy element formula is optimized, which creates a material base condition for the culture and the grain refining of a high-temperature phase and a strengthening phase in solid solutions so as to finally develop the high-strength heat resistant aluminum alloy material.
