RESEARCH TO DETERMINE COMPOSITION OF DISPERSED PHASES IN REFRACTORY METAL ALLOYS. PART II. CONCENTRATION GRADIENTS IN REFRACTORY METAL BINARY DIFFUSION COUPLES.

Abstract

The concentration gradients present in pure metal and alloy incremental, two-component, diffusion couples were determined by means of electron beam microanalysis. In a parallel study the equilibrium chemistry of individual phases present in two-phase alloys of the Ta-Pt system was determined by means of electron beam microanalysis. The crystal structures, lattice parameters and chemistries of dispersed phase precipitates in two Mo-TZC alloys (1.6 Ti-0.58 Zr-0.13C) were determined. One alloy was asextruded and the other as-swaged. The combined techniques of X-ray diffraction and electron beam microanalysis were employed. The phases were shown to be alloy carbides of the TiC and ZrC systems. (Author)
