High Velocity Forging Technology

Abstract

A report is made of manufacturing methods program to investigate the dynamic response of selected aerospace alloys deformed by upset forging from room temperature to 1950F at impact strain rates from quasi-static (100 in/in/ sec.) to 8000 in/in/sec. This was accomplished in two phases. Phase 1 included the selection and the ambient temperature forging of ten representative aerospace materials to evaluate the effects of strain rate on material forge ability and to select four of the most responsive materials for extensive testing at elevated temperatures. In Phase 2, the four selected materials were forged at varying combinations of strain rate and temperature to determine the conditions for optimum forge ability and mechanical properties including tensile yield, tensile ultimate, elongation, hardness and fatigue.
