Testing of Columbium and Columbium Alloys
Source abstract
Abstract
Results of laboratory testing of columbium and columbium alloys as corrosion resistant materials are summarized. Columbium, having the lowest density of the refractory metals group, has higher thermal conductivity than Zircaloy-2 or austenitic stainless steel. In chemical corrosion tests the Nb-10Ti-10Mo alloy was found to be much less resistant than unalloyed columbium. Oxidation resistance of columbium was improved by alloying for flowing air exposures at 2000 F and 2200 F for times up to 100 hours. The alloy Nb-1Zr was completely resistant to the various liquid metals except for welds that suffered intergranular corrosion. The Nb-7V alloy seemed to be more practical than the Nb-10Ti-10Mo alloy on the basis of weldability and good high temperature strength properties. 6.3.5
