Abstract

The invention discloses a solution and straightening method for titanium alloy boards, and belongs to the technical field of preparation of titanium alloy. The method comprises the process steps of arranging a lower base plate to bear the titanium alloy boards, arranging an upper base plate to balance pressure of a pressing machine, then conducting edge trimming and overlapped assembly on the boards, then putting the boards into an annealing furnace for solution treatment and heat treatment, and finally, utilizing the pressing machine for straightening. The key point of the solution and straightening method lies in that the solution, ageing and annealing temperature and time of the titanium alloy boards and acting force of the pressing machine are controlled, in this way, vertically-downward pressure is applied to the titanium alloy boards in the cooling process, and then the boards are straightened online in the cooling process. The input for process equipment is small, solution and press-straightening of the boards can be achieved simply through a conventional heating furnace, the annealing furnace and the pressing machine, the overall cost is low, the flow is simple and convenient, the application range is wide, and industrialized application of the process can be achieved in most factories.

Description

technical field [0001] The invention relates to the technical field of titanium alloy preparation, in particular to a solid solution straightening method for titanium alloy plates. Background technique [0002] With the rapid development of anti-armor weapons, various types of artillery weapons with excellent armor-piercing capabilities have been continuously introduced, and higher and higher requirements have been put forward for the protection capabilities of armored vehicles, that is, the armor thickness and weight of tanks are constantly increasing. The weight of armored combat vehicles has increased by 15% to 20% in more than ten years, and the continuous increase in vehicle weight has seriously affected its maneuverability. High mobility, lightweight, high defense capability and high reliability are the inevitable direction for the development of armored vehicles in the future. In order to improve the maneuverability of combat troops, their armored vehicles need to be ...
