Molybdenum, rare metal molybdenum, niobium and other components, in metal processing. For titanium plate production, what are the effects?

   1, C content

   The carbon content has a great influence on the toughening and brittle transition temperature of the titanium plate. With the addition of C in the titanium plate, the plastic resistance is added, the transition temperature of the toughened and brittle transition is obviously increased and the temperature scale of the transformation is widened, which is rooted in the addition of C content, which increases the brittleness of the titanium plate.

   2, Mn content manganese can restrain the transformation of ferrite pearlite, promote the formation of bainite, and then improve the durability of the titanium plate. With the addition of Mn content, the toughening and brittle transition temperature drops.

   3, Mo content

   Molybdenum can refine the grain and form the second phase particle, thus advancing the titanium plate's endurance and affecting the ductile brittle transition temperature.

   4, S, P content

  Impurities such as sulfur and phosphorus tend to segregate at grain boundaries, decrease grain boundary surface energy, occur intergranular cracking, reduce brittle cracking stress, and affect the ductile brittle transition temperature.

 5, Si content

 Silicon has an adverse effect on the tolerance. The determination of Si content also has a certain effect on the decrease of ductile brittle transition temperature.

 6, Nb content

 In the process of hot rolling, niobium has the effect of deposition strengthening, which makes the strength of the titanium plateincrease and the resistance decreases, but Nb can refine the grain, and then improve the strength and endurance of the titanium plate.

   7, Ti content

   Because of its strong affinity with nitrogen, titanium has a strong affinity to nitrogen, which forms TiN. It can fix nitrogen elements in titanium plates. TiN can disperse in the titanium plate with fine dispersion particles. It can decrease the austenitizing temperature of the slab, manipulate austenite grain growth, then reach the intention of refining grain, and improve the data tolerance.

  8, V, Al content

  Vanadium and aluminum have the effect of deposition strengthening, fine-grained strengthening and grain boundary strengthening in titanium plate, which is beneficial to the decrease of ductile brittle transition temperature.
