Recent Information on Long-Time Creep Data for Columbium Alloys

摘要

The memorandum summarizes recent information relating to long time creep parameters for columbium alloys. The available creep data for columbium alloys through mid-1963 were previously reported in DMIC memorandum 170. Long-time-creep test programs are being conducted by NASA Lewis Research Center, Thompson Ramo Wooldridge, and Oak Ridge National Laboratory. Data from these and other selected sources for time greater than 10 hours are complied in this memorandum. (Author)
