Abstract

Abstract Iron (Fe)–tungsten (W) system (50:50 in mol%) metastable alloy powder including solid solution and the bulk body were prepared by mechanical alloying (MA) and shock compression, respectively. The MA-treated Fe–W powder and the shock consolidated bulk body showed by X-ray diffraction an almost single phase of body-centered cubic (BCC) structure. The lattice parameter of BCC structure of the MA-treated powder for 21 h was smaller than that of pure tungsten. It was confirmed that Fe and W dispersed well within submicron level in the bulk body by the electron probe micro analysis (EPMA).
