Abstract

The present invention relates to the heat treatment process of wrought Mg-Zn-Mn alloy, and features that the heat treatment process includes the following steps: solid dissolving of the extrusion formed alloy material at 400-440 deg.c for 2-4 hr and water quenching to room temperature, heating to 90 deg.c and maintaining for 16-24 hr, further heating to 180 deg.c and maintaining for 12-16 hr, and air cooling to room temperature. The wrought Mg-Zn-Mn alloy through the said heat treatment has greatly raised strength and toughness and wide application range.

Description

technical field

[0001] The invention relates to a heat treatment process for deformed magnesium alloy materials, in particular to a heat treatment process for deformed magnesium alloy materials containing zinc and manganese by adopting solid solution and double-stage aging. Background technique

[0002] With the development of the world economy, environmental issues and energy issues have become the focus of attention. As the pillar of the 21st century, materials have shown changes in five aspects: from ferrous metals to non-ferrous metals, from metallic materials to non-metallic materials, from structural materials to functional materials, from multi-dimensional materials to low-dimensional materials , changing from a single material to a composite material. Magnesium and magnesium alloys have a series of advantages such as high specific strength, high specific stiffness, strong vibration damping, electromagnetic shielding and radiation resistance, easy cutting and process...
