Abstract Scope |
Strain-induced melt activation (SIMA) technique is gaining huge importance in manufacturing industries, necessitates for low-cost production. In this research work, the processing parameters such as effective strain, reheating isothermal temperature and holding time in modified strain-induced melt activation (M-SIMA) process of Al-7Si are optimized using response surface methodology. The responses mainly, Ultimate Tensile Strength (UTS, MPa) and Elongation (El, %) are considered as a function of different processing parameters (effective strain, isothermal temperature and holding time). The regression analysis method is used to develop the mathematical model for responses, and the covenant of the developed model is endorsed by the variance method. It has been observed that desirable values of effective strain, isothermal temperature, and holding time to be 0.6, 585°C, and 30 min, respectively. Based on process parameters for M-SIMA process, a high strength (UTS = 206 MPa) with superior ductility (El = 32%) of Al-7Si alloy is observed. |
