Today semi-solid metal (SSM) forming is an attractive materials processing method as an alternative to traditional forging or casting. The advantages of SSM forming are: (a) materials are of better ability to fill a mold, (b) dies are of longer life and (c) products can have better mechanical properties. Usually, the semi-solid slurry, prepared by a stirring process is used directly for forming products or solidified to billets, which are formed after being reheated to a semi-solid state. Strain induced melt activated (SIMA) forming is another method to produce a semi-solid slurry. For this method, residual strain is stored in a billet and a global structure is evolved by the strain energy stored in the billet after reheating. In the SIMA process, an alloy having the sufficient stored energy by cold working is heated to a mushy zone. During heating, recovery and recrystallization occur before liquid formation with the aid of the stored energy. Reaching the mushy zone, liquid is formed by preferential melting at grain boundaries with high energy state, and penetrates into high angle boundaries of recrystallized grains. Accordingly, the amount and distribution of the stored energy by cold working, conservation time and temperature are the most critical factors in the SIMA process since they control the recovery and recrystallization kinetics and the uniformity of the resultant microstructure. The purpose of this research is; (a) introduction of a modified SIMA process to a Cu34%Zn2%Pb brass alloy and (b) examination of the separate effect of each stage of the conventional SIMA process on microstructure and mechanical properties of the same brass alloy.
