Abstract:

Creep age forming technology is a method which uses the creep character of metal, combining forming and ageing heat treatment process to improve the fatigue property of material. A series of creep tests for 7B04-T7451 aluminum alloy were carried out, and then the formed aluminum alloy was taken to do fatigue tests. General mathematical expressions for S-N curve were introduced. The most used power function expression was transformed to fit the S-N curve. Compared with different S-N curves, the fatigue property of creep age formed aluminum alloy is improved at medium and low stress.
