  • METHOD FOR IMPROVING MECHANICAL PROPERTIES OF ALUMINUM ALLOY CASTINGS
    Publication number: 20150252460
    Abstract: The present invention discloses a method for improving mechanical properties of aluminum alloy casting. The advantages of the present invention lie in: combining heat-treatment with thermal painting; dividing the solution treatment of conventional T6 heat treatment process into two separate solution treatments, which avoids deformation and overheating of the casting due to melting of the ternary eutectic structures with low melting point, thereby improving efficiency of the heat-treatment and lowering the amount of energy consumed and the cost of production.
