| Abstract | ||
| This approach involves theoretical and experimental study on the effect of cold working percentage on the hardening exponent (n). The important of this object deals with relation of hardening exponent on the spring back and mechanical properties. The materials used was aluminum alloy, which as a round specimen and compressed in different cold working percentage. For the research the following condition are obtained, that the hardening exponent, spring back of metal and hardness increase with increase of cold working percentage. This explain the behavior of metal during forming process and explain the change witch obtain in micro structure ,the hardness and spring back of metal is directly proportional with strain hardening exponent. | ||
