Laws of the creep of metallic materials at high temperatures

The uniaxial tension with various strain rates for the alloy V95ochT1 at the room temperature and at the temperature of aging 165°C is investigated experimentally for finding of the rational modes of deformation. The range of deformation rates, close to strain rate at superplasticity, at the tempera...

Description
Summary:The uniaxial tension with various strain rates for the alloy V95ochT1 at the room temperature and at the temperature of aging 165°C is investigated experimentally for finding of the rational modes of deformation. The range of deformation rates, close to strain rate at superplasticity, at the temperature of aging was found when the value of deformation at destruction is maximum. Increasing or decreasing of the deformation rate leads to decrease of the strain value at which the material is destroyed. Increasing the preheat period leads to a decrease in the strain value at fracture at temperature of aging. The elastoplastic characteristics are reduced in the alloy in the cold state after the full aging at 165°C without load.
