OSTI ID:7120853
The microhardness, ultimate tensile strength, and elastic modulus of 44 to 74 ..mu..m AISI 9310 rapidly solidified powder, consolidated by shock waves with energies varying from 94 to 770 kJ/kg and a shock duration of 2 to 3 ..mu..s, are presented. The compacts produced have a variation in diamond pyramid hardness from 390 to 510, in strength from 0 to 1.4 GPa, and in elastic modulus from 66 to 181 GPa. The hardness and strength reach a maximum at 500 kJ/kg shock energy. The strength and elastic modulus results imply that 800 kJ/kg shock energy produces complete interparticle bonding.
