BERYLLIUM (BRUSH QMV PRESSED BLOCK): CREEP-RUPTURE PROPERTIES
Technical Report
·
OSTI ID:4259668
The short-time creep-rupture propenties of Brush QMV beryllium block, hot pressed at 1050 deg C, were investigated. Heating rates of 350 to 520 deg F/ sec were used to reach final tenipei-atures of 400, 850, 1100, 1300, and 1550 deg F. stress levels were 30, 60, and 90% of the nominal yield strength dif the material at the various test temaperatures investigated. Resisthnce heating methods were used. strain characteristics during heating and at temperature varied consistently ovcr the range of temperatures and stresses investigated. A maximum testing time-span of 2 min at temperature was observed for the iests. Where failure occurred, the rupture times varied erratically. (auth)
