Document Type and Number:
WIPO Patent Application WO/2023/226166
Kind Code:
A1
Abstract:
A preparation method for an aluminum-based composite material reinforced with a shape memory ceramic and having an adjustable austenite content. Raw materials of the composite material comprise a shape memory ceramic and an aluminum powder. In the raw materials of the composite material, the mass content of the shape memory ceramic is 1-90%, and the balance is aluminum powder. The shape memory ceramic used is single crystal particles based on cerium-containing zirconium dioxide, which comprise the following components: 3-12 mol% of CeO2 and the balance of ZrO2. According to the preparation method, the steps of heating austenitizing and densification processing are used during the preparation process, so as to achieve the preparation with the austenite content being adjustable.
