Abstract

Hardness and microstructural behavior in a dissimilar joint between Cu-DHP copper alloy and the AISI 316L steel was stablished by means of rotary friction welding. The joint was made with a speed of 1,200 r/min in bars of 12 mm diameter and 100-mm length. Welding pressure of 30 MPa was applied. The process variables were welding time, pressure and forging time. It was possible to determine in the thermally and thermomechanical affected zone that there is the presence of α and β phase and cuprous oxide (Cu2O) on the Cu-DHP side and the presence of the equiaxial austenitic phase in the AISI 316L steel with ferrite in the matrix. Hardness increased from 89.7 HV in copper and 217 HV in AISI 316L to 250 HV in ZTMA.
