Rapidly Solidified Microstructures and Precipitation in a Ti-5.5w/o Ni Alloy
Recently the application of rapid solidification (RS) techniques to Ti alloy systems has received increased attention. The systems studied include both conventional alloys such as Ti-6Al-4V, Ti-5Al-2.5Sn and novel compositions containing B, C, and other additions. Another class of Ti alloys that is being investigated by RS processing involves eutectoid forming additions. This paper presents results of work on a rapidly solidified near-eutectoid Ti-5.5 w/o Ni alloy. RS ribbons of this alloy were produced by melt-spinning and were characterized by optical and scanning electron microscopy techniques. The microstructure of the RS ribbon was compared with that produced by conventional ingot metallurgy (IM) approach. The effect of aging treatments below the eutectoid temperature on both RS and IM microstructures was also studied.
