Abstract : The effects of thermal-mechanical processing variables on short-time 3000 F tensile properties of W 0.6 Nb alloy were determined by correlating both tensile properties and thermalmechanical variables with microstructure and cold work condition of this alloy. From these correlations the spread in 3000 F tensile and yield strength values (22,000 to 63,310 psi and 10,5000 to 61,500 psi respectively) is attributed to variations in processing factors and time at 3000 F during tensile testing. The correlations also serve as a guide for processing the alloy and for evaluating the alloy suitability for 3000 F service application. (Author)
