Abstract
• Models and process maps for the property responses of Al 7075-molybdenum composite were reported. • The developed regression models were validated to fit for the prediction of the property response. • The process maps show varying combination of the process parameters. The need for high strength and high-temperature performance Al 7075 is on the rise. Moreso, the process map and model for such a process is necessary. Present report involved the design of a process map for property optimization/minimization in the development of Al-7075 composite infused with thermally stable molybdenum (Mo) particles. Mo particles were varied at 5, 10, and 15 wt. % while sintering temperature was varied at 350, 450, and 550 °C. Properties evaluated are porosity, sintered density, hardness, yield strength, elongation, elastic modulus, specific heat capacity and thermal conductivity. The obtained process maps showed varying proportions in minimizing/maximizing each response property. The developed models for each property response were validated to be fit in predicting the responses.
