Preparation of a Solid-Phase Compound from an Aluminum–Zinc Alloy under Conditions of Low-Temperature Superplasticity
摘要
Abstract—
A method for pressure welding of cylindrical workpieces in the solid state of an aluminum–zinc alloy in a vacuum at a temperature of 250°C under conditions of low-temperature superplasticity is developed. Tensile tests showed that the strength of the welding joints is 90–95% of the ultimate tensile strength of the base material.
