Industrial equipment Identifiers: Dynapak P HYSICAL PROPER Y TEST ON HIGH- NERGY-RATE FORGED UPSETS FROM PH15-7Mo s eel indicate that it is possible to achieve excelle t ductility in both longitu inal and tra sv rse directions. The wide spread in data for t e number of specimens ined dictated the need for further development before the optimum forging temperature nd mount of defor a ion per blow o insure these properties can be firmly established. Materials studied were AISI 4340, Ti-6Al4V, H-11 tool steel and PH15-7Mo. Forging paramet r for cissor bracket configurations were established. (Author)
