摘要：
Full-density W-Ti alloys have been fabricated by a new, hot-explosive-compaction (HEC) technique. The alloy billets that 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 post-consolidation 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. Crown copyright (C) 1999 Published by Elsevier Science S.A. All rights reserved.
