Embodiment 1

[0021] Using TiB (2vol.%) reinforced titanium-based composite material as the matrix, the TiB-reinforced titanium-based composite material is firstly melted by electron beam technology, in which the current is 9mA, the voltage is 40kV, the scanning speed is 10mm / s, and the heat output is 3.6J / mm . Then, low-temperature aging treatment is carried out on the melted composite material, wherein the aging temperature is 500°C, the holding time is 8h, and it is cooled with the furnace.

Embodiment 2

[0023] The difference between this embodiment and Embodiment 1 lies in the electron beam melting treatment, in which the current is 6 mA, the voltage is 60 kV, the scanning speed is 10 mm / s, and the heat output is 3.6 J / mm.

Embodiment 3

[0025] The difference between this embodiment and Embodiment 1 lies in the electron beam melting treatment, wherein the current is 6 mA, the voltage is 50 kV, the scanning speed is 10 mm / s, and the heat output is 3 J / mm.

Abstract

The invention relates to a reinforced phase regulation and control method for a TiB reinforcing titanium-based composite. The reinforced phase regulation and control method comprises the following steps that firstly, an electron beam technology is utilized to conduct melting treatment on the TiB reinforcing titanium-based composite; and then the melted composite is subjected to low-temperature aging treatment. According to the reinforced phase regulation and control method for the TiB reinforcing titanium-based composite, the nano-scale reinforced phase and the sub-micron TiB reinforced phasecan be obtained and distributed in a net structure, and the titanium-based composite has the excellent mechanical property.
