Abstract

The invention discloses a high-strength heat-resistance aluminum alloy material and a preparation method thereof. The alloy material comprises the components in percentage by weight: 1.0-10.0% of Cu, 0.05-1.5% of Mn, 0.01-0.5% of Cd, 0.01-0.5% of Ti, 0.01-0.2% of B, 0.01-1.0% of Zr, 0.01-1.0% of Mo, 0.05-5% of RE and the balance of Al. By adopting high-quality melt and solid solution and phase diagram principle as guide and preferably choosing alloy main elements Cu, Mn and RE formula, the invention reduces alloy standard solid phase temperature range and solves the problems of large hot crack tendency, low high-temperature strength of products and the like in casting; in addition, by preferably choosing low-cost multielement microalloying element formula, the invention creates material condition for culturing and grain refining of medium-high and strengthening phases of the solid solution; and moreover, by optimizing the melting and heating processing technology, the invention realizes sufficient culturing and full play of grain refining of the medium-high and strengthening phases of the solid solution so as to finally prepare the high-strength heat-resistance aluminum alloy material.

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 ...
