摘 要：<正> Various Mo-base alloys with high meltingtemperature were processed into ribbons andfoils by the arc melt-spinning and the arc melthammer-anvil technique. The preparation of ribbonand foil was introduced. The mechanical proper-ties, the surface topology and the microstructureof rapidly solidified Mo-base alloys containingB were examined. A strong grain refinement anda strong age-hardening response were observedon the as-quenched and the age specimens, theprecipitates which cause age hardening wereidentified to be Mo2B in Mo-B alloys, Mo2B andZrB2 in Mo-Zr-B alloys, and Mo2B and ThB4 inMo-Th-B alloys. The results indicate that thehigh strength Mo-base alloys containing borideprecipitates can be developed by rapid solidifica-tion technique.
