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.
