Titanium Hex Flange Bolts
Thermal processing, mainly forging, rolling and extrusion is the basic means of production of Titanium Flange semi-finished products and products. In view of the titanium flange structure to the thermal processing process with a strong sensitivity, so the correct selection and mastery of the process parameters is not only to ensure the accuracy of the product shape and size is very important, but also the internal quality of the product is a key factor.
Compared with general metal structure materials, titanium flange thermal processing is characterized by large deformation resistance, deformation temperature range is narrow. The hexagonal crystal structure of titanium is not easily deformed. In order to improve plasticity, it is necessary to heat the metal to the b-phase region above the phase change point for the so-called b-processing. But because of the titanium flange superheating tendency, high-temperature heating will cause b grains to grow rapidly, but if the deformation is not enough, the formation of coarse Weiss organization after cooling will significantly reduce the period of the alloy and fatigue strength, and months of this superheated organization in the subsequent heat treatment to eliminate the difficult, so the current production of finished products or finished products before a fire of the starting temperature of the thermal processing regulations do not have to be over the critical point Tb. Due to the deformation resistance of titanium flange to The deformation resistance of the titanium flange is very sensitive to the reduction of deformation temperature or deformation rate increase, and even stop forging temperature can not be too low. The constraints of these two factors, so that most of the titanium flange finished product processing temperature range is limited to 800 to 950 ℃, it is not easy to master. But the ingot open billet, the temperature range can be extended to 850 a 1150 ℃, in the subsequent fire times of processing, and then reduce the temperature.
Titanium flange alloy poor thermal conductivity, in the rapid deformation, the heart of the workpiece temperature rise quickly, due to slow heat transfer and easy to cause overheating, while the workpiece surface temperature is low, and easy to form surface cracks, so the processing process needs to pay attention to master the deformation rate and the amount of deformation.
