TENSILE AND CREEP-RUPTURE PROPERTIES OF DISILICIDE-COATED UNALLOYED MOLYBDENUM SHEET AT 2800, 3000, AND 3200 F

Abstract

Tensile and creep-rupture properties were obtained for disilicide- coated unalloyed molybdenum sheet (0.040 in.) at 2800, 3000, and 3200 F. The base metal substrate was disilicide coated approximately 0.0025-in. thick. A two-color Shawmeter (optical pyrometer) provided an accurate and convenient method to determine and to control test temperatures on the coated specimens. The ultimate tensile strengths at 2800, 3000, and 3200 F were approximately 12, 11, and 10 Ksi, rively. The stress values to cause 2% creep in 2 hrs at 2800, 3000, and 3200 F were 4.3, 3.8, and 3.0 Ksi.
