Titanium rod standard!

α alloy contains a certain amount of elements that stabilize the α phase, and is mainly composed of α phase in equilibrium. α alloy has a small specific gravity, good thermal strength, good weldability and excellent corrosion resistance. The disadvantage is low room temperature strength and is usually used as heat-resistant and corrosion-resistant materials. Alpha alloys can usually be divided into full alpha alloys (TA7), near alpha alloys (Ti-8Al-1Mo-1V) and alpha alloys with a small amount of compounds (Ti-2.5Cu).

Titanium alloys can be divided into three categories according to their phase composition: α alloys, (α+β) alloys and β alloys, which are represented by TA, TC and TB in China respectively.

①α alloy contains a certain amount of elements that stabilize the α phase, and is mainly composed of α phase in equilibrium. α alloy has a small specific gravity, good thermal strength, good weldability and excellent corrosion resistance. The disadvantage is low room temperature strength and is usually used as heat-resistant and corrosion-resistant materials. Alpha alloys can usually be divided into full alpha alloys (TA7), near alpha alloys (Ti-8Al-1Mo-1V) and alpha alloys with a small amount of compounds (Ti-2.5Cu).

② (α+β) alloy contains a certain amount of elements that stabilize the α phase and β phase. The structure of the alloy in equilibrium is α phase and β phase. (α+β) alloy has medium strength and can be strengthened by heat treatment, but its welding performance is poor. (α+β) alloys are widely used, among which the output of Ti-6Al-4V alloy accounts for more than half of all titanium materials.

③ β alloy contains a large number of elements that stabilize the β phase and can retain all the high-temperature β phase to room temperature. Beta alloys can usually be divided into heat-treatable beta alloys (metastable beta alloys and near-metastable beta alloys) and heat-stable beta alloys. Heat-treatable β alloy has excellent plasticity in the quenched state, and can achieve a tensile strength of 130~140kgf/mm2 through aging treatment. Beta alloys are usually used as high-strength and high-toughness materials. The disadvantages are heavy specific gravity, high cost, poor welding performance, and difficult cutting processing.
