Pt-Rh Alloys: Investigation of Creep Rate and Rupture Time at High Temperatures

摘要

The results of experimental investigation of creep rate and rupture time of the alloys of Pt-Rh system are presented in this paper. Selected alloys with 7-40 wt.-% Rh content were examined using a universal device for tensile testing of materials at high temperatures, and monitoring structure changes of the samples by electron microscopy. Investigations were performed in the temperature range between 1200℃ and 1700℃ at a stress between 2 MPa and 15 MPa.
