Tóm tắt

AbstractThe effect of temperature on the yield stress of polycrystalline α‐zirconium has been examined at temperatures between 77 and 900 K. A strong temperature dependence of the yield stress (interrupted in the temperature ranges 300 to 400 K and 500 to 700 K where the yield stress is independent of temperature) indicates the occurence of the thermally activated processes during deformation. The activation volume at the onset of deformation has been determined as a function of temperature in the range 77 to 523 K.
