상세내용	ABSTRACT Misch metal (Mm), consisting of Ce and La, was added to Ti–45Al–3Mo–2Nb alloys in order to investigate phase transformation and microstructural changes. The pseudo-binary phase diagram was estimated via PANDAT softwareTM. The addition of Mm caused a decrease in both the fractions of a2/c lamella and the b0 phase, and served as an important factor for a collapse of lamellar structures. In addition, Mm significantly decreased the colony size of the alloy, resulting in an increase in high-temperature tensile yield strength of * 40% for the alloys with 0.3 at% Mm at 800 C. It appears that the addition of Mm affects the phase stability and increase the proportion of the c phase. The microstructural changes, with respect to Mm additions, were discussed in terms of structural observations during isothermal heat treatments.
