An Experimental Research Facility for Creep-Rupture Testing of Tantalum Alloy T-lll

摘要

We have developed a research facility for computer-controlled elevated temperature tensile testing of refractory metallic alloys in an inert environment In an application to tantalum alloy T-lll, we have determined that a two-hour creep rupture life can be achieved at 1204°C (0.45 Tm) and 1300°C (0.48 Tm) if the applied true stresses are maintained below 46 ksi (317 MPa) and 36 ksi (248 MPa) respectively.
