Abstract

© The Society for Experimental Mechanics, Inc. 2017. Aluminium chips are generally recycled via foundry methods. In this research, the use of a combined method through powder metallurgy techniques (Sintering + thixoforging) has been proposed as a more effective low cost and alternative processing for recycling of scrap aluminium chips (AA7075). Aluminium chips, TiO2 and spherical ceramic powder are mixed and pre-milled as matrix and reinforcement, respectively, and other additives (Pure Boron, BN and TiC and Graphite) in different amounts, are used as well to improve the properties of the final composition. The effects of the different additives in the microstructure, mechanical properties essentially impact shock values are compared. Fracture surfaces were analyzed by scanning electron microscopy (SEM) for detailed damage evaluation.
