Improvement of ADC12 Alloy by Optimizing CSP Process Parameters via Multiple Nonlinear Regression Analysis

In order to improve the quality of ADC12 alloy billets prepared by Chips Solid Pressing (CSP) process, the effects of pressing temperature, pressure and packing time on the density of ADC12 alloy billets were investigated by using the orthogonal array and multiple nonlinear regression analysis. The results indicated that the pressing temperature has the greatest effect on the density of the billets, and it is followed by pressing pressure and packing time. The optimized process parameters, including a pressing temperature of 250oC, pressing pressure of 640MPa and packing time of 45 seconds, can be used to obtain the most compact billets of ADC12 alloy prepared by CSP process.
