Abstract
In this study, high-carbon, chromium alloy steel (100Cr6) having the initial spheroidized microstructure
was welded using the rotary friction welding method. The effects of process parameters such as friction time
and friction force were experimentally investigated. The friction welded joints were produced of two 100Cr6
steel rods. In order to examine the microstructure and mechanical properties of the friction welded 100cr6 steel
joints, tensile and hardness tests were conducted. The microstructure of the weld zone was examined by optical
microscopy. It was found that after cooling, martensitic structure is obtained at the core and periphery of the
weld joint. It was found that the tensile strength of friction welded samples is increased with increasing time and
force of friction up to a certain level and then decreases again. Hardness measurements show a higher hardness
at the center of the weld joint in comparison with its periphery.
