Abstract

The invention discloses a method for preparing a low-cost detonation-proof titanium alloy plate. The method includes: 1. designing the composition of the target product titanium alloy plate; 2. selecting raw materials for preparing corresponding elements; Titanium alloy ingots are obtained by vacuum self-consumption smelting for the first time, and then cut and forged to obtain slabs; 4. The slabs are rolled by multiple fires to obtain titanium alloy plates; 5. Heat treatment; 6. Anti-explosion titanium alloys are obtained by surface treatment plate. According to the principle of alloying, the invention designs and obtains the detonation-proof titanium alloy plate with few components and low alloy element content, which reduces the component cost, plays the role of reducing surface density and strengthening, and improves the strength of the detonation-proof titanium alloy plate under the premise of ensuring the strength of the detonation-proof titanium alloy plate. Its toughness and plasticity enable the anti-detonation titanium alloy plate to produce uniform plastic rheology under the attack of the shock wave, absorb more energy, effectively resist the shock wave brought by the explosion, and improve the anti-detonation performance of the anti-detonation titanium alloy plate.
