Abstract

True stress-true strain data are given for nominally pure molybdenum (99.95 pet) over the temperature range −196° to 1540°C (0.027 to 0.63 T/TJ. Strain rate sensitivity was determined by rate change tests and stress relaxation tests. Inhomogeneous yielding and strain aging effects were observed. The yield stress and tensile strength depend markedly on temperature below 400°C and are insensitive to temperature in the range 400° to 800°C. The ductile to brittle transition range is +25° to −25°C. Strain rate sensitivity and stress relaxation effects are very large near room temperature.
