Mechanical Properties of a Metal-Matrix Composite Based on Copper and Aluminum, Obtained via Shear Deformation under Pressure
- 6 Downloads
Results are presented from studying the structure and mechanical properties of an Al–Cu–Al metal-matrix composite obtained via shear under pressure on Bridgman anvils with grooves. The tensile strength is 485 MPa, considerably higher than that of either pure aluminum or copper. The main mechanism of failure is a viscous fracture along the Al matrix with no notable stratification along the interphase boundaries.
