Investigation of Microstructure, Mechanical Properties and Inhomogeneity in Commercial Purity Aluminiumin in the ARB Process
Author(s):
Abstract:
In this research, 13 passes of accumulative roll bonding (ARB) process is performed on A 1050 sheets. The microstructural evolution to access of grains with nanometer size during ARB process is investigated. Moreover, the change in strength and elongation of the sheets during the cycles of process is studied by uniaxial tensile test in 3 directions (rolling direction (RD), transverse direction (TD) and at an angle of 4 owith respect to RD); and then the inhomogeneity of mechanical properties in these directions is investigated.The tensile strength of sheet is increased by increasing the number of ARB cycles.The elongation of specimen is decreased rapidly at the first cycle of ARB; and it is subsequently increased gradually.The inhomogeneity of mechanical properties of specimen is increased by performing the ARB process.
