Nonequilibrium alloy bulk material including metastable solid solution in Tungsten (W)-Silver (Ag) system (70:30 in mol%) was prepared by mechanical alloying (MA) and shock compression. The MA-treated W-Ag system powders showed an X-ray diffraction pattern of single phase of body-centered cubic (BCC) structure. The lattice parameters of BCC structures of the MA-treated powders were larger than that of pure tungsten. The X-ray diffraction pattern of the shock-consolidated bulk material formed in a specific low pressure range did not change significantly from that of the MA-treated powder.
