Titanium and Titanium Alloy Bars
Titanium alloys can be divided into three categories according to the composition of the phases: α alloy,(α+β) alloy and β alloy, which are respectively expressed by TA, TC and TB in China.
① The α alloy contains a certain amount of elements with stable α phase and is mainly composed of α phase in equilibrium state. α alloys have small specific gravity, good thermal strength, good weldability and excellent corrosion resistance. Disadvantages are low strength at room temperature, and they are usually used as heat resistant and corrosion resistant materials.In general, α alloys can be divided into full α alloys (Ta7), nearly α alloys (Ti-8Al-1Mo-1V) and α alloys with a few compounds (Ti-2.5Cu).
② (α+β) alloy contains a certain amount of elements with stable α phase and β phase, and the microstructure of the alloy in equilibrium state is α phase and β phase.The (α+β) alloy has moderate strength and can be strengthened by heat treatment, but the weldability is poor.(α+ β) alloys are widely used, and the output of Ti-6Al-4V alloys accounts for more than half of all titanium materials.
① β alloy contains a large number of elements stable β phase, high temperature β phase can be retained to room temperature.β alloy can be divided into heat treatable β alloy (metastable β alloy and nearly metastable β alloy) and heat stable β alloy.The heat-treatable β alloy has excellent ductility in the quenched state and can achieve tensile strength of 130~140kgf/mm2 by aging treatment.β alloys are commonly used as high strength and high toughness materials.Disadvantages are significant, high cost, poor welding performance, machining difficulties.
