摘 要：<正> The splat foils with 30～35 μm thickness and the spun ribbon with 50～55 μm thickness of Mo-4Th-0.4B andMo-8Th-0.8B alloy were made by arc melt hammer-anvil and melt spinning techniques.Both alloys have highhardness and strong age hardening response,especially for Mo-8Th-0.8B alloy.The precipitates associated with agehardening were identified to be ThB4（Tetragon） and Mo2B（C16,BTC）.The times of reaching age hardening peak forboth alloys are not the same,depended on the precipitation extent of Th and B solutes from metastable solid solution.Astrong grain refinement was observed.Present and previous work indicate that new high strength Mo alloys can be de-veloped by rapid solidification techniques.
