Abstract

The invention discloses a production process of a high-strength Ti80 titanium ring. The production process comprises the following steps: 1, cogging and forging are conducted, 4500T equipment is used, preheating is conducted at 750-845 DEG C for 1.5-2.5 hours, heating to 985-1125 DEG C, and heat preservation is conducted for 385-405 minutes; 2, 2000T equipment is used, and heat preservation is carried out at the temperature of 1000-1065 DEG C for 185-235 minutes; 3, the 2000T equipment is used, and heat preservation is conducted at the temperature of 945-995 DEG C for 185-240 min; 4, the 2000T equipment is used, and heat preservation is conducted at the temperature of 935-985 DEG C for 105-155 min; 5, the 2000T equipment is used to obtain a finished product at the temperature of 925-975 DEG C; and 6, annealing is conducted at the temperature of 755-805 DEG C. Through the production process of the Ti80 titanium ring, the tensile strength, the yield strength, the ductility, the shrinkage rate, the impact strength and the hardness of the Ti80 titanium ring in experimental data are all superior to those of standard requirements after detection and comparison, so that the requirements of various practical applications are met.

Description

technical field [0001] The invention relates to the technical field of nonferrous metal production technology, in particular to a production technology of Ti80 titanium ring. Background technique [0002] Ti80 titanium alloy is a new type of Ti-Al-Nb-Zr-Mo series α+β titanium alloy independently developed in my country. It has comprehensive properties such as high strength, high toughness, weldability, corrosion resistance, good low cycle fatigue and high impact toughness. Compared with the traditional titanium alloy TC4, the plasticity has increased by 3% to 5%, and the impact toughness has increased by nearly 2 times, is widely used in aviation, spaceflight, navigation and other fields, especially in the field of marine engineering has a good application prospect. At present, the field of marine engineering has gradually begun to use large-scale forging billets to prepare pressure vessels, pressure-resistant shells and other components. The larger the size of the forging ...
