According to the composition of titanium alloy phase can be divided into three categories: alloy, alloys and alloys, the Chinese were to TA, TC, TB said.
1, alloys containing a certain amount of stability of and -phase elements, equilibrium alloyof and phases. alloys have moderate strength, and heat strengthened, but the welding performance is poor. alloys are widely used, in which Ti-6Al-4V titanium alloy in production in more than half full.
2, alloys containing a certain amount of stability of -elements, mainly by the equilibrium phase.small proportion of alloy, hot and strong, good, good weldability and excellent corrosion resistance, the disadvantage is the low temperature strength, usually used as a heat-resistant materials and corrosion resistant materials. alloys generally can be divided into full- alloy (TA7), near alloy (Ti-8Al-1Mo-1V) and a small amount of compounds of the alloy (Ti-2.5Cu
3, -phase alloys containing a large number of stable elements, high-temperature phase can befully retained to room temperature. alloys generally can be divided into alloys can be heat treated(metastable alloys and nearly metastable alloys) and thermal stability of alloys. can beheat-treated alloy quenched state has excellent ductility and tensile strength through aging to reach 130 ~ 140kgf/mm2. alloy materials commonly used for high strength and toughness. Than the major drawback is high cost, poor performance welding, cutting difficult.
Heat-resistant titanium alloys can be divided according to purpose, high-strength alloy, corrosion resistant alloys (titanium - molybdenum, titanium - palladium alloys, etc.), low-temperature alloys and special featuresalloy (titanium - iron hydrogen storage materials and Ti - Ni shape memory alloys) . Typical alloy compositionand performance table.
Heat-treated titanium alloy heat treatment process can be obtained by adjusting the phase of differentcomposition and organization. Generally believed that the fine equiaxed organization has good plasticity, thermal stability and fatigue strength needle-like tissue has a high rupture strength, creep strength andfracture toughness equiaxed and needle-like hybrid organization has a better overall performance.According tothe composition of titanium alloy phase can be divided into three categories: alloy, alloys and alloys, the Chinese were to TA, TC, TB said.
