Hot Explosive Consolidation of W-Ti Alloys: Microstructural Effects

Abstract

Full-density W-Ti alloys have been fabricated by a recently developed, hot-explosive-compaction (HEC) technique. The alloy billets, which are formed, consist of W grains embedded in a generally discontinuous, preferentially oriented Ti-rich matrix. The effects of the use of different types of precursor powders, the influence of the W-Ti ratio on the dispersability of the W grains in the alloy, and the postconsolidation anneal control of the Ti-rich matrix were of primary interest. The alloy billets were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). The major features of the technique and the microstructural properties of the W-Ti alloys are presented.
