METHOD FOR INCREASING THE STRENGTH OF MATERIALS HAVING AGE HARDENABILITY THROUGH SEVERE DEFORMATION PLUS AGING TREATMENT AT LOW TEMPERATURE

摘要

The present invention is to greatly increase the strength of the aluminum alloy aging ability, ; I. The process of the solution heat treatment (Homogenization) for about the alloy, ; II. The process of quenching in order to quench the alloy, ; III. ECAP process to process, and at least once at a predetermined temperature or less, ; IV. Consists of a process for the low temperature aging (Aging) processing on the treated alloy and the invention relates to a method of increasing the yield strength of the material, characterized in that age hardening ability to process the order for the above process. ; can be the case with the present invention after the solution treatment with respect to the metal, such as aluminum alloy which age hardening ability by applying the ECAP technique to provide a much higher yield strength than the metal is the conventional method with a minimum of processing and the ECAP At the same time, the material is also flexible and can be obtained over a certain amount
