Abstract
The present invention relates to a novel material (Ti-120) for bulletproof vests. The present invention is titanium alloy which adopts titanium as the base, chromium (an alloy element) is added in the titanium alloy, and the alloy density is 4.53 g/cm<3>; an alloy bulletproof sheet with the thickness of 2.6mm can resist the attack by a 54-model pistol within the distance of 3 to 15 meters at any angle, the bullet weighs 5.6g, the alloy bulletproof sheet can not be struck through and cracked, and the depth of each concave-downward bullet crater is more than 6mm; compared with the bulletproof vests made from usually-adopted high-strength steel, the weight of the bulletproof vests made from the novel material is reduced by 25%; compared with the bulletproof vests made from pure titanium, the weight of the bulletproof vests made from the novel material is reduced by 13%. The present invention has the advantages of favorable processing performance, light weight, corrosion resistance, no magnetic performance, no toxin, etc.; the present invention is an ideal metallic material for making bulletproof vests, and has a broad prospect for making bulletproof helmets, bulletproof shelters and other bulletproof harnesses.
Description
The present invention is the manufacturing process technology field that belongs to a kind of material for antiballistic protective clothing, particularly about adopting the titanium alloy field that density is little, bulletproof performance is good, is applicable to the equipment and the protection of army.
With having that the previous crops material for antiballistic protective clothing uses: High Strength Steel Plate, pure titanium plate, Kev draw the anti-material that plays.It is good that High Strength Steel Plate is made the flak jackets elastoresistance, low price, but because its density is big, equipment personnel's burden is heavy, influences the performance of its maneuverability and fighting capacity, intensity is high-leveled and difficult with machine-shaping, and is perishable, need carry out surface treatment etc.Kev draws and anti-plays that the material snappiness is good, comfortable and easy to wear, density is little, corrosion-resistant but cost an arm and a leg and be difficult to equip our troops in a large number, and can make barrier propterty reduce greatly, so that lose efficacy in case make moist; Very responsive to uviolizing, easily aging, need special protective measure.Kev draws is obeying that the depression in crater reaches 40mm deeply behind the bullet, and people's secondary is caused injury, though and pure titanium plate is lighter than High Strength Steel Plate, but the still big (13.5kg/m of area density
2), tensile property is not ideal.
In order to overcome above-mentioned shortcoming, purpose of the present invention provides a kind of density little, safe and reliable material for antiballistic protective clothing.It is that nearly α type alloy (Ti-120) is made material for antiballistic protective clothing that the present invention adopts the Ti-Cr of low alloying.
The chemical ingredients Ti-0.5%-1.8 of Ti-120 alloy of the present invention (weight) %Cr, when being lower than 0.5 (weight) % as if chromium, strength of alloy is lower, crackle also appears in crater back side bulge place, when chromium was higher than 1.8 (weight) %, the plasticity of alloy reduced, and crackle also appears in crater back side bulge place.
The manufacturing process of alloy Ti-0.5%-1.8 of the present invention (weight) %Cr alloy is as follows:
A. press the ingredient composition of Ti-0.5%-1.8 (weight) %Cr alloy, the compacting electrode adopts the vacuum consumable electrode arc furnace melting;
B. hammer cogging: at electric furnace or heavy oil stove internal heating, cogging temperature is 950 ℃-1080 ℃, and total deformation reaches more than 75%, and soaking time is decided according to the size of ingot casting:
C. hot rolling: heating is carried out in electric furnace or induction furnace, and hot-rolled temperature is 850 ℃-950 ℃, and hot rolling sex change amount is between 50%-70%;
D. process annealing: process annealing is carried out in electric furnace, and the process annealing temperature is 700 ℃-800 ℃, and soaking time is 0.5 hour-1.5 hours;
E. cold rolling: cold rolling reduction is more than 50%;
F. finished product thermal treatment: finished product thermal treatment is carried out in electric furnace, and heat treated annealing temperature is 650 ℃-750 ℃, and soaking time is 0.5 hour-1.5 hours.
Make armour with alloy of the present invention, thickness 2.6mm can resist 54 formula pistols, and bullet weighs 5.6 grams, and in 3-15 rice distance and attack at any angle, armour is not worn and do not split, and bulletproof performance is good, caves in only below 6mm in the crater.The density of alloy is 4.53g/cm
3, the armour area density is little only to be 11.8kg/m
2, corrosion-resistant, without any need for surface treatment; There are not damp failure and problem of aging.Under same pretective acreage, the material for antiballistic protective clothing that the present invention makes than high-strength steel loss of weight 25%, and has good processing properties than pure titanium loss of weight 13%.Having magnetic in light weight, corrosion-resistant, no, advantage such as nontoxic, is desirable material for antiballistic protective clothing.
Embodiment
1. prepare burden: by alloying constituent Ti-0.8 (weight) %Cr batching, the every heavy 2kg of electrode needs Cr16 to restrain, sponge titanium 1984 grams, and each ingot casting needs 12 electrodes, altogether 24kg.
2. compacting electrode: in the middle of the sponge titanium of alloying element chromium cloth in Φ 50mm * 300mm electrode mould, add and be pressed into electrode.
