The Mechanical and Thermal Properties of Tungsten and Tzm Sheet Produced in the Refractory Metal Sheet Rolling Program. Part I

摘要

The report describes an evaluation program that was performed to obtain preliminary design data for tungsten and TZM sheet produced in the Refractory Metal Sheet Rolling Program. Tungsten sheet 0.060- and 0.10-in. thick, and TZM sheet 0.020-, 0.040-, and 0.060-in. thick, were investigated. Both materials were studied in the optimum (warm worked and stress relieved) and recrystallized conditions. Mechanical properties evaluated included tensile, notched-tensile, compression, bearing, shear, creep, thermal-stability, weld joint efficiency. The recrystallization and bend-transition temperatures were also determined. Physical properties that were evaluated included density, thermal expansion, thermal conductivity and specific heat. Tensile and bend evaluations were performed on the TZM sheet after application of two commercial coatings, PFR-6 and W-3. (Author)
