Abstract

The invention discloses a method for preparing a large-sized TC6 titanium alloy bar, which comprises the following steps: 1. pulling a titanium alloy ingot into square and forging; 3. Slitting and blanking, and then carrying out the second drawing and rounding forging; 4. Performing solution heat treatment and aging heat treatment to obtain large-sized TC6 titanium alloy bars with a cross-sectional diameter of 100mm to 210mm and a length of 2000mm to 4000mm. In the present invention, the rough as-cast structure in the ingot is broken by one-time squaring and forging, and the number of times of forging is reduced. Two to three times of drawing and rounding forging are carried out under the fire, which effectively breaks the long structure and further refines the structure, solves the shortcomings of low processing efficiency and long process of conventional large-scale titanium alloy processing, and effectively reduces the processing of large-scale titanium alloys. Time forging fire times.

Description

technical field

[0001] The invention belongs to the technical field of titanium alloy material processing, and in particular relates to a preparation method of a TC6 titanium alloy large-sized bar. Background technique

[0002] TC6 titanium alloy is a martensitic α-β two-phase titanium alloy with good comprehensive properties. Its nominal composition is Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si, containing α-stabilizing element Al, isomorph β-stabilizing element Mo and eutectoid β-stabilizing elements Cr, Fe and Si. TC6 titanium alloy has high room temperature strength and good thermal strength below 450℃. The alloy also has excellent thermal processing performance, low deformation resistance and high plasticity. TC6 alloy is mainly used to manufacture parts such as compressor discs and blades of aero-engines. The alloy can also be used as a medium-strength alloy to manufacture aircraft bulkheads, joints and other load-bearing structural parts and fasteners for different purposes. T...
