As far as possible when cutting Angle should be no more than allow the plate length and width of the deviationAlloying editorTitanium alloy is based on titanium to join other alloy elements.Titanium has two homogenous different crystal: under 882 ℃ to close the six-party alpha titanium structure, above 882 ℃ for body centered cubic beta titanium.Alloying elements according to their influence on phase change temperature can be divided into three categories:(1) a stable alpha, increase the temperature of the phase transition element for alpha stable elements, such as aluminum, carbon, oxygen and nitrogen.Including aluminum titanium alloy main alloy elements, it is to improve the alloy at room temperature and high temperature strength, reduce weight, increasing the elastic modulus have obvious effect.(2) stable beta phase, to reduce the phase transition temperature elements for beta stable elements, and can be divided into two isomorphous and eutectoid type.The application of titanium alloy productsThe former are molybdenum, niobium, vanadium, etc.;The latter has a chromium, manganese, copper, iron, silicon, etc.(3) the phase transition temperature impact elements to neutral elements, such as zirconium, tin. Oxygen, nitrogen, carbon and hydrogen is the main impurity of titanium alloy.Oxygen and nitrogen in the alpha phase has larger solubility, to strengthen titanium alloy has a significant effect, but it is plastic.Usually prescribed titanium content of oxygen and nitrogen in under 0.15 ~ 0.2% and 0.04 ~ 0.05% respectively.Hydrogen in the alpha phase solubility is small, dissolve excess hydrogen yield in titanium alloy hydride, alloy become fragile.Usually controlled under 0.015% hydrogen content in titanium alloys.The dissolution of hydrogen in titanium is reversible and can be removed using a vacuum annealing.[1]
