Quick plastic forming (QPF) was developed as a high-volume, hot blow forming process for automobile components, enabling larger volume applications than traditional superplastic forming (SPF). One critical aspect of the process is the tribological interaction between the forming tool and the aluminum blank, as this impacts formability, surface quality, and tool durability. While QPF has been successfully implemented for automobile components, many opportunities exist for improving the tribological condition during the process, including the die coating or treatment, the lubricant, and the fundamental understanding of aluminum/iron adhesion under QPF conditions (450 °C). This work reviews key tribological issues affecting QPF and identifies areas where additional research is required. |
