<p>This study investigates the wear characteristics of SUS 321 and Inconel 600 in the hot forming of Ti‒6Al‒4V alloy. To understand the wear behavior of the tool materials, the pin-on-disc tests at the high temperature of 650&#xa0;℃ were designed based on the FE simulation of the hot forming of the titanium alloy. The experimental procedure was established based on the Taguchi method. Sensitivity of parameters for the pin-on-disc test on the wear volume was analyzed utilizing the main effects and contour plots. To analyze wear characteristics, the roughness and micrographs of the wear track on the pins were observed. The results show that SUS 321 and Inconel 600 are significantly influenced by the normal force and the sliding distance rather than the sliding velocity. The wear of SUS 321 is caused by a combination of abrasive wear and the micro-cutting, whereas Inconel 600 is slightly affected by abrasive wear. A modified Archard’s model was proposed to characterize the wear behavior of SUS 321 and Inconel 600 considering the hardness of hard and soft materials. The proposed model well-predicts the wear characteristics for both materials.</p>
