Özet
St-Cu (stainless steel and copper) parts were friction welded with the aim to optimize the process parameters in the present study. The joints obtained with various process-parameter combinations were subjected to a tensile test. Empirical relationships were developed to predict the strength of the joints using RSM (the response-surface methodology) and the coherency of the model was tested. The tensile properties, microhardness variations, SEM, the EDS analysis and X-ray diffraction (XRD) analysis of the welded specimens were evaluated. It was found, with an ANOVA analysis, that the friction pressure/friction time relation has the largest influence on the tensile strength of the joints followed by the rotational speed. However, it was also found that the formation of intermetallics at the interface is responsible for a higher hardness and lower tensile strength of the friction-welded stainless steel-copper joints.
