Forging Methods To Improve The Mechanical Properties Of Titanium Alloy Bars

According to news from the financial world on February 20, 2024, according to an announcement from the State Intellectual Property Office, Western Superconducting Materials Technology Co., Ltd. applied for a project called "A forging method to improve the uniformity of mechanical properties at the end of titanium alloy rods", which was publicly disclosed. No. CN117564199A, application date is November 2023.

The patent abstract shows that the invention discloses a forging method for improving the uniformity of mechanical properties at the end of titanium alloy rods, which adopts continuous circular cross-section forging → cross-fire reversal heating forging → alternating edge forging during drawing → U Anvil forming forging process; it uses high-temperature continuous forging in the opening fire to accelerate the dynamic recrystallization of the as-cast structure, and controls the blank to have a circular cross-section to improve the uniformity of circumferential deformation; in the recrystallization fire, the phase below the phase change point is used. Cross-fire reversal forging above the change point suppresses the impact of the end dead zone on the uniformity of the structure; enters the two-phase zone through alternating edge faces for forging, and finally combines the forming fire U-shaped anvil forging to improve the metal flow at the end Uniformity. The forging method of the present invention effectively improves the end effect problem of large-size titanium alloy rods caused by the limitations of the free forging method, resulting in large forging dead zones at the ends and uneven metal flow, and at the same time reduces the removal of the ends. quantity, greatly improving the yield rate of titanium alloy rods.
