Abstract

The invention discloses a manufacturing method of a titanium alloy steel plate. The manufacturing method specifically comprises the following steps: 1, titanium and iron are added into a smelting furnace to be heated into a molten state; 2, silver powder, aluminum powder, zinc powder and a preservative are added for oxygen isolation heating; 3, sodium hydroxide powder is added and stirred, and after cooing, the sodium hydroxide powder is modeled into a blank; 4, firing rolling is carried out for three times; and 5, ventilating cooling is carried out. The manufacturing method has the beneficialeffects that conductive powder is added into a titanium alloy component and ionized during smelting, good electrical conductivity of a titanium alloy during linear cutting is ensured, and thus an alloy material is prone to being cut; and through firing rolling for multiple times, the temperatures of firing rolling of the first two times are the same, third-time firing rolling is selectively carried out below the phase transformation point, and properties of the plate can be adjusted to meet corresponding requirements.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy plate preparation, and specifically refers to a method for preparing a titanium alloy steel plate. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance. In the 1950s and 1960s, high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes were mainly developed. [0003] A batch of corrosion-resistant titanium alloys were developed in the 1970s. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. Titanium alloys are mainly used to make aircraft engine compressor components, followed by structural parts of rockets, missiles and high-speed aircraft. [0004] However, due to the high hardness of titanium alloy, it is easy to crack, difficult to cut, inconvenient to pro...
