HIGH ENERGY RATE FORGING DEVELOPMENT.

Abstract

High energy rate dynapak forging of a thin webbed gear blank configuration was studied using Vascojet 1000 and 4340 steel alloys. With this given configuration laps or cracks at the web-rim intersection are markedly affected by final web thickness and percent upset per blow. Sound parts were produced with web thickness of about .180 inches. Description of the forging processes along with all forging parameters are given and the results examined in terms of dimensional reproducibility hardness surveys, tensile properties and metallographic analysis.
