High-performance TA1 bar wire and preparation method thereof

Abstract

The invention belongs to the field of titanium and titanium alloy preparing and machining, and particularly relates to a high-performance TA1 bar wire and a preparation method thereof. The high-performance TA1 bar wire contains smaller than or equal to 0.15 wt% of Fe, smaller than or equal to 0.15 wt% of O, smaller than or equal to 0.05 wt% of N, smaller than or equal to 0.10 wt% of C, smaller than or equal to 0.008 wt% of H and the balance titanium and unavoidable impurities. According to the high-performance TA1 bar wire, the tensile strength is between 350 MPa and 450 MPa, the yield strength is between 240 MPa and 380 MPa, the percentage elongation after fracture is larger than or equal to 25%, and the percentage reduction of area is larger than or equal to 60%. The high-strength, high-toughness and excellent-comprehensive performance TA1 pure titanium bar wire which is suitable for the medical field and the aerospace field and reaches the standards of imported wires is obtained bycontrolling raw material alloy elements and a heat treatment system, the use intensity of TA1 pure titanium is further improved while the excellent service performance is shown, and the wide application prospect is achieved in the engineering field.

Description

Technical field [0001] The invention belongs to the field of titanium and titanium alloy preparation and processing, and specifically relates to a high-performance TA1 rod wire and a preparation method thereof. Background technique [0002] TA1 belongs to α-type titanium alloy. It is an industrial pure titanium alloy that does not contain other alloying elements. It generally has a single-phase α structure in the annealed state, has good structure stability and heat resistance, good welding performance, and weld performance close to the matrix , Process plasticity is good, easy to process and shape, generally used in occasions that require high corrosion resistance but low strength requirements, such as chemical pipelines, pressure vessels, etc. [0003] Because the strength of TA1 pure titanium alloy is not high, it cannot meet the performance requirements of components in some special situations, such as the mechanical properties of imported materials. Effectively improving the ...
