Abstract

The invention provides a high-performance elastic alloy material for an aerial hyperbaric cabin. The production method of the high-performance elastic alloy material comprises the following steps: (1) vacuum melting; (2) electroslag refining; (3) forging an ingot billet; (4) hot-rolling molding; (5) cold drawing; and (6) performing heat treatment. The high-performance elastic alloy material obtained by the method has high tensile strength up to 160 / 250(MPa); a wrapping test proves that the alloy material is not ruptured after being wound around not less than 15 circles, which is obviously superior to the national standard; and in the eventthat the alloy material is bent for 90 degrees forwardly and reversely on the same phase plane, the outer side of the bent position is not cracked and ruptured.

Description

technical field [0001] The invention relates to a novel high-performance elastic material suitable for a high-temperature chamber and a production method thereof, in particular to the improvement of the elastic material cobalt-based 3J21 alloy. Background technique [0002] With the continuous update and development of aerospace vehicles, the requirements for material performance are getting higher and higher. The working conditions of aerospace vehicles are very complicated, and most components are in service under high composite stress, high temperature and environmental erosion. The main requirements are high temperature resistance, low temperature resistance, high specific strength, high specific stiffness, fatigue resistance, corrosion resistance, long life and low cost. In the current elastic alloy market, the elastic material used in high-end products is cobalt-based 3J21 alloy. This material has good corrosion resistance and high tensile strength, which can fully mee...
