| description | The invention relates to the field of alloy processing, in particular to a preparation method of a T6-state large-specification 7075 aluminum alloy extruded bar. According to the preparation method of the T6-state large-size 7075 aluminum alloy extruded bar, pre-stretching is combined with optimization of a heat treatment process, the mechanical property of the prepared T6-state large-size 7075 aluminum alloy extruded bar from the edge part to the core part is remarkably improved, industrial batch production is easy to achieve, and the production cost is reduced. And the high-performance index of the T6-state large-specification 7075 aluminum alloy extruded bar is met, and the mechanical property is stable. Experiments show that according to the T6-state large-specification 7075 aluminum alloy extruded bar prepared through the preparation method, the overburning phenomenon does not occur in the microscopic structure, and the mechanical property of the T6-state large-specification 7075 aluminum alloy extruded |
