Characterization of an explosively consolidated rapidly solidified Fe-16Ni-9Cr-5Mo-2Cu alloy powder
Vacuum gas atomized Fe-16Ni-9Cr-5Mo-2Cu alloy powder was dynamically consolidated using explosive techniques. The microstructure and tensile properties were evaluated in the as-shocked condition and after various heat treatments. Results showed the product to be fully dense and in a shock hardened condition after consolidation. Low bulk temperatures from the dynamic consolidation process allowed retention of the rapidly solidified microstructure of the powder except for the thin interparticle areas where metallurgical bonding (melting) has occurred. Thermal treatments resulted in decreasing strength as ductility increased. Microstructural observations and x-ray line broadening analysis were consistent with the changes in tensile properties. 7 refs., 7 figs., 1 tab.
