Effect of Solution Treatment on the Microstructure of Ti-C Alloys

Article Preview

Abstract:

The work concerns a new group of titanium alloys with properties improved due to the presence of carbon. Investigated alloys were melted in a vacuum induction furnaces with copper water cooled crucibles. It was showed the influence of the solution temperature in range of 875 to 975oC on the number, size and distribution of carbides in pure titanium with content of 0.2 wt.% carbon and on the hardness test of researched alloys. The observed changes in the microstructure and properties are the result of phase transformations taking place during heating: α + TiC α α + β β + TiC.
