The phase equilibria in the
Ti–TiMn2–ZrMn2–Zr region of the Ti–Zr–Mn system have been
investigated using DTA, X-ray diffraction analysis, optical microscopy and
electron microprobe analysis. The solid phases involved are b (Ti,Zr), (Ti,Zr)Mn2 continuous solid solutions and r-TiMn. The liquidus
and solidus projections, as well as the TiMn2–ZrMn2, Ti50Mn50–Zr50Mn50
and Ti60Mn40–Zr67.5Mn32.5 vertical
sections, have been constructed. The phase diagram is characterized by a
minimum on the solid surface caused by the existence of a minimum in the Ti–Zr
fusibility diagram, and a U-reaction that involves r-TiMn, TiMn2 and b-Ti based solid
phases and liquid.
