Abstract

The invention discloses a wedge-shaped lining plate for hard brittle high modulus magnesium alloy, which comprises a wedge-shaped lining plate body (1) made of aluminum alloy, the wedge-shaped lining plate body (1) comprises a groove plate (2) and a cover plate (3), one end of the wedge-shaped lining plate body (1) is a wedge-shaped end part (4), and the other end of the wedge-shaped lining plate body (1) is a wedge-shaped end part (5). The upper surface of the groove plate (2) is provided with a rectangular groove (5) which is consistent with the hard brittle high modulus magnesium alloy in width and height, and the wedge-shaped end part (4) is 3-5mm higher than the upper surface of the rectangular groove (5). The invention further discloses an edge crack control rolling method for the wedge-shaped lining plate of the hard brittle high-modulus magnesium alloy and application of the obtained magnesium alloy plate to aerospace, rail transit and high-end precision equipment. By adopting the wedge-shaped lining plate, the hard and brittle high-modulus magnesium alloy plate which is good in processing quality and high in production efficiency is effectively obtained.

Description

Technical field [0001] The present invention relates to a method for rolling the wedge plate and edge-cracking and controlled application of hard and brittle high modulus magnesium alloys belonging to the technical field of metal processing material. Background technique [0002] Magnesium alloys have low density, specific strength and specific stiffness, earthquake, strong noise reduction capabilities, easy-to-many excellent performance machining in the aerospace, automotive, electronics and many other fields have a good prospect. In particular, with the rapid development of new energy automotive industry in recent years, as well as in carbon and carbon peak at background, magnesium alloy as a typical lightweight materials, its application has been more and more attention. [0003] However, low modulus of elasticity of magnesium alloys, because of poor ductility, limiting the application of magnesium alloy as a structural material. In order to improve the modulus of elasticity o...
