Abstract

The invention relates to the technical field of manufacturing of titanium alloy materials and watch parts, and particularly discloses a high-temperature-resistant and easy-to-process titanium alloy which comprises the following components in percentage by weight: 3 percent to 8 percent of Al, 0 percent to 1 percent of Si, 0 percent to 3 percent of V, 1 percent to 5 percent of Zr, 0 percent to 3 percent of Mo, 0 percent to 5 percent of Sn, 0.5 percent to 1.5 percent of Nd, less than or equal to 2 percent of other few impurity elements and the balance of Ti. The invention further discloses a titanium alloy watch appearance part manufacturing method based on the titanium alloy material. The method comprises the steps of treating a blank to form a blank A; mounting a mold; heating the mold and putting the blank A; conducting primary hot forming: after the blank A is subjected to heat preservation for a preset time, pressurizing at a preset strain rate and maintaining the pressure for a preset time to form a blank B; forming V-shaped grooves in the two bent faces of a large bent structure of the blank B, and forming a blank C; conducting repeated hot forming on the blank C; conducting repeated hot forming to form a blank D; cooling; machining; and conducting surface treatment.

Description

technical field [0001] The invention relates to the technical field of manufacturing titanium alloy materials and watch parts, in particular to a method for manufacturing titanium alloys and titanium alloy watch appearance parts. Background technique [0002] In the watch industry, 316L stainless steel is usually used as the raw material for watch appearance parts. Due to the high density and heavy weight of stainless steel, the wearing comfort is not high, and the element Ni is often added to stainless steel to improve its corrosion resistance. Ni element and human skin Contact will cause allergies in some people, and it is not biologically friendly. The titanium alloy material has a low density, and its mass is only half that of 316L steel under the same volume; its corrosion resistance is also better than that of 316L steel, and it can withstand artificial sweat and salt spray tests for a longer period of time without being corroded; at the same time, titanium alloy also ...
