Development of Carbide-Strengthened Niobium Alloys. Part I. Molybdenum in Niobium-Carbon Alloys.

摘要

The effects of molybdenum alloying additions to niobium on the carbide phases and their precipitation behavior were investigated. The experimental alloys included Nb-0.1C,Nb-15Mo-0.1C and Nb-30Mo-0.1C. After selected heat treatments the microstructural changes were determined by metallography and the carbide phases were extracted and identified by X-ray diffraction and chemical analysis. The results are essentially in agreement with recent phase diagram determinations. (Author)
