Abstract : Notched- and unnotched-tensile evaluations were made for determination of the notched-tensile brittle-ductile transition temperature on the 0.060-in. tungsten sheet and the 0.040-in. TZM sheet as scheduled in the original scope of the program. Density measurements were made on the different sheets of various thicknesses of the tungsten and TZM material evaluated under the original scope of the program. Elevated-temperature unnotchedtensile evaluations at 2200, 2500, and 3000F were conducted on the TZM sheet as specified in the extended phase of the TZM program. The notched- and unnotchedtensile evaluations for analysis of the notched-tensile brittle-ductile transition temperature among different sheets and heats were also completed for the extended work on the TZM sheet. Arrangements were made to weld coupons of the 0.040-in. TZM and the 0.060-in. tungsten sheet by the TIG process and to weld coupons of 0.040-in. TZM sheet by the electron beam process for subsequent evaluation of the mechanical properties of the welded sheet.
