 Molybdenum plate elements impact on the physical properties of titanium plate
Rare metal, the composition such as molybdenum, niobium content in metal processing. For titanium plate production, which influence, the analysis is as follows:
1, C content
Carbon ductile to brittle Tungsten copper alloy of titanium plate has a great influence, followed by titanium plate in the C content added, plastic resistance data to add, ductile to brittle transition temperature
Increase, change of temperature scale also widened, its roots in the C content added, increases the brittleness of the titanium plate.
2, Mn content
Manganese can refrain from ferrite and pearlite transformation, promote bainite formation, and then improve the titanium plate patience, follow the add of Mn content, ductile to brittle transition
Temperature drop.
2, Mo content
Molybdenum can refine grain and constitute the second phase particles, a titanium plate in order to move forward the patience, ductile to brittle transition temperature.
3, S and P content
Impurities such as sulfur, phosphorus is gathered in the grain boundary, decline in grain boundary can appearance, the intergranular cracking, reduce the brittle cracking stress, affect the ductile to brittle transition temperature.
4, Si content
Silicon has adverse effect on patient, the decision of the Si content of ductile to brittle transition temperature drop also will effect.
5, Nb content
Niobium in the hot rolling process have deposition strengthening effect, make the strength of the titanium plate increases, patience is reduced, but Nb can refine the grain, and improve the strength of the titanium plate
And patience.
6, Ti content
Titanium due to its and nitrogen has a strong affinity, contact form TiN, can fix nitrogen in the titanium plate elements, TiN in titanium plate with small dispersion particle distribution, can
Enough to drop the slab heating austenitizing temperature, manipulation of the austenitic grain growth, and then reach the intention of fine grains, useful to improve patient information.
7, V, Al content
Vanadium and aluminium deposition in titanium plate strengthening, fine-grain strengthening and grain boundary strengthening effect, and then is advantageous to the ductile to brittle transition temperature decreased.
