Title:
THERMAL TREATMENT METHOD WITH CONTROLLABLE ADDITIVE MANUFACTURING ALUMINUM ALLOY STRENGTH AND ELONGATION
Document Type and Number:
WIPO Patent Application WO/2021/077598
Kind Code:
A1
Abstract:
A thermal treatment method with controllable additive manufacturing aluminum alloy strength and elongation, comprising: within a range of 180-475°C, performing solution treatment, aging treatment or solution-aging treatment on an additive manufacturing aluminum alloy, wherein the additive manufacturing aluminum alloy is an additive manufacturing Al-Mg-Sc-Zr-Mn alloy. Different thermal treatment conditions are provided for the additive manufacturing Al-Mg-Sc-Zr-Mn alloy to obtain materials having different strength and elongation, controllability of the additive manufacturing Al-Mg-Sc-Zr-Mn alloy strength and elongation is achieved, and a foundation is laid for application. The thermal treatment method is short in path, convenient to operate, and capable of achieving large-scale production.
