Abstract

In this study, a new
metal matrix composite material was produced by sintering from cast iron and
bronze shavings made by recycling melting method. In the production of metal
matrix composite material, 90% CuSn10 as a matrix material and 10% GGG40 cast
iron as a reinforcement material were used. The chips having the same
dimensions were mixed in a homogeneous mixture and pre-formed under a pressure
of 1146 MPa and then sintered at 875 °C. The mechanical properties and porosity
of the produced materials are characterized and the mechanical properties are
compared with the mechanical properties of the bronze material in bulk state.
According to the results, the mechanical properties of the material produced by
the sintering method are very close to that of the bronze material in the bulk
state.
