摘要
Metastable alloy bulk body including solid solution in iron (Fe)-copper (Cu) system was prepared by mechanical alloying (MA) and shock compression. The MA-treated Fe-Cu system (50:50 in mol%) powder showed an X-ray diffraction pattern of a single phase of face-centered cubic (FCC) structure. The lattice parameter of FCC structure of the MA-treated powder was larger than the one of pure copper. The X-ray diffraction pattern of the shock-consolidated bulk body did not much change from the one of the MA-treated powder. Instrumental chemical analyses revealed only slight changes in compositions by the MA-treatment and shock-compression.
