Summary

Photographic and pyrometric studies have been made of the high voltage discharge forming process for the manufacture of porous metal compacts to show the pattern of heat generation in the product during the process. The work has also indicated the temperatures that can be achieved in the process and has allowed the optimum forming attitude for the method to be defined. The effect of initial conditions and instabilities in the process on both heat generation and the final product is discussed.
