Influence of manganese on sintering processes in the Ti-Fe system. 1. Volume changes in sintering of Ti-Fe-Mn compacts
An investigation was made of the influence of manganese on the sintering processes in the titanium-iron system in the area of temperatures of existence of the first ternary eutectic point. Powders of titanium obtained by hydride-calcium reduction, ferromanganese, and types PZh4M2 and V3 iron were used. A figure presents data on the character of the volume changes in sintering of compacts of mixtures of titanium and iron powders with and without manganese. The x-ray analysis was made on a DRON-0.5 instrument. The profiles of intensities of the x-ray lines of Ti(Fe, Mn) phase present in specimens of mixture II are shown. With an increase in sintering temperature the line, which is diffuse at 1050 degrees C, gradually narrows, and at 1250 degrees C a doublet appears. At the time, the lattice parameter changes from 0.2976 for unalloyed TiFe to 0.2991 nm for Ti(Fe, Mn) obtained at 1250 degrees C. To obtain Ti(Fe, Mn) compounds of the required composition, it is necessary to take into account the amount of evaporated manganese.
