Abstract

In recent years, metallic multilayer materials have been the focus of many researchers and different industries. Cold roll bonding is one of the methods for producing layered composites which, compared to other composite manufacturing methods is more economic and has the ability to produce layered composite with different material. In this research, for the first time and according to ASTM-E561 and using compact tension specimens, plane stress FRACTURE TOUGHNESS for thin three-layer Al/Cu/Al composite sheets produced by Cold Roll Bonding Process was investigated. The FRACTURE TOUGHNESS is an important parameter in the design and their analysis can predict crack growth and life for material that has crack. In addition to the FRACTURE TOUGHNESS, MECHANICAL PROPERTIES and tensile fracture surfaces were evaluated by using uni-axial tensile test, micro hardness and scanning electron and optic microscopy, respectively. Results showed the value of tensile strength, micro hardness and FRACTURE TOUGHNESS for Al/Cu/Al layered composite compared to initial Al 5052 and pure Cu increased, the main cause of this increase is applied high strain and cold working. Value of FRACTURE TOUGHNESS for Al/Cu/Al layered composite received 38.7MPa.m1.2 that compared to initial Al5052 and pure Cu, 81% and 165% enhanced, respectively. Results of SEM demonstrated that ductile fracture mechanism were observed for Al/Cu/Al composite such as initial samples, but the difference is that dimples for composite layers are shallower and smaller compared to initial samples.
