Abstract

The invention discloses a titanium alloy plate and a processing method thereof, and belongs to the technical field of alloys. The titanium alloy plate comprises the following raw materials: Ti, Al, V,Fe, silver fluoride, zirconia fiber and silicone, and the proportion of silver fluoride to silicone to zirconia fiber is (0.04-0.06): (0.02-0.04): (0.01-0.03). The titanium alloy plate processing method comprises melting, hot rolling, cold rolling and other steps. According to the titanium alloy plate and the processing method thereof, silver fluoride, silicone and zirconia fiber are used as a reinforcing system, and the mechanical properties and corrosion resistance of the titanium alloy plate are improved.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a titanium alloy plate and a processing method thereof. Background technique [0002] Due to the advantages of high specific strength, high temperature resistance, and corrosion resistance, titanium alloys are widely used in aerospace, ships, weapons, chemicals, automobiles, medical care and other fields. The amount of titanium alloys is also one of the important symbols of the advanced level of aviation equipment. . [0003] The titanium alloys used to make thin plates mainly include industrial pure titanium and titanium alloys such as TC1 and TC2. The general strength level of industrial pure titanium is not greater than 600MPa, and the annealed strength level of TC2 is 685MPa, which does not reach more than 700MPa. With the improvement of the pressure level of aviation and other weapons and equipment, the existing thin plates cannot meet the high-pressure resistance requiremen...
