Design of Hybrid Composites from Scrap Aluminum Bronze Chips

Aluminum bronze material has high thermal conductivity, wear resistance, corrosion resistance, and good mechanical strength which is widely used in structural applications, grinding tools, etc. Certain studies have shown that these composites containing a small amount of iron and nickel exhibit improved bending strength and higher strain energy. The main purpose of the present work is to apply the liquid phase sintering process to determine the optimal sintering conditions and to evaluate the interface of aluminum and the scrap aluminum bronze chips with different reinforcement elements (TiC, BN, Gr etc.). A second aspect of this work is to evaluate the effect of the sintering conditions on the microstructure and mechanical properties such as hardness and compression behavior. In the frame of the present work, an original idea of producing a hybrid composite has been developed by using scrap aluminum bronze chips. This consists of mixing and compacting aluminum with aluminum bronze (ASTM B148) chips through press moulding and sintering.
