Stress Rupture Properties of Alloy 783

Alloy 783 because of its high temperature oxidation resistance, excellent mechanical properties and low thermal expansion coefficient, not only can be applied in aviation gap control component, can also be used in high temperature bolt USC Turbine serving. High temperature mechanical properties of the alloy, particularly the stress rupture properties is essential for the alloy can be used normally under severe conditions. The effects of different Al contents, stress and temperature on the alloy rupture life were tested by the method of orthogonal experiment and analyze the main factors affecting the performance of the alloy.
