Western Superconductor develops forging methods to improve the mechanical properties of titanium alloy bars

Financial news on February 20, 2024, according to the announcement of the State Intellectual Property Office, Western Superconducting Materials Technology Co., Ltd. applied for a forging method called "A forging method to improve the uniformity of mechanical properties of titanium alloy bar ends", public number CN117564199A, the application date is November 2023.

The patent abstract shows that the invention discloses a forging method for improving the uniformity of mechanical properties of the end of a titanium alloy bar, which adopts a process of open continuous circular section forging → transfire secondary reversing heating forging → edge surface alternating forging → U-anvil forming forging; The dynamic recrystallization of the cast structure was accelerated by continuous forging at high temperature, and the circular cross-section of the billet was controlled to improve the uniformity of the circumferential deformation. In the recrystallization phase, cross-fire secondary commutation forging was used to suppress the influence of the end dead zone on the microstructure uniformity. Enter the two-phase zone through the forging mode of alternating edges, and finally forge in the combined forming fire U-anvil to improve the end metal flow uniformity. The forging method of the invention effectively improves the problem of the end effect caused by the large dead zone of the end forging and the uneven metal flow of the large titanium alloy bar due to the limitation of the free forging method, and simultaneously reduces the cutting amount of the end and greatly improves the yield of the titanium alloy bar.
