Failure of uranium alloys with molybdenum and zirconium under shock-wave loading in the temperature range form-196 to 800 deg C

摘要

The cleavage fracture of the two alloys U- 1.4mass percent Mo and U- 1.4 mass percent Mo -0.7 mass percentZr is investigated in the temperature range from - 196 to 800 degC. The critical levels of shock-wave loading corresponding tothe nucleation of cleavage defects and total macroscopic failureof the sample are determined. Data on the failure of the alloy atdifferent temperatures are obtained by metallographic analysis.
