Sintering Kinetics of Self-Lubricating Ti-48%Al-2%Nb-2%Cr Alloys with Fluoride Lubricants
The study reports the sintering kinetics of Ti–48Al–2Nb-2Cr composites (TANC) with addition of different weight contents of LiF, NaF,CaF2 and 38%CaF2-62%BaF2 eutectic solid lubricant (BC) using OM, SEM and DSC. The microstructure of TANC composites with different CaF2 and BC content is analyzed. Additions of solid lubricants to TANC matrix have significant influences on densification degree of the composites. Densities increase with sintering temperature and time, decrease with addition amount of solid lubricant.
