Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forging cloth, in particular to a multi-gradient forging cloth for titanium alloy beta phase forging and an application method thereof. BACKGROUND

[0002] At present, the beta phase forging above the phase transition point is mainly adopted in the production of ultra-high strength titanium alloy, so as to form a typical basketweave structure. The alpha phases in the basketweave structure are staggered with each other, which greatly increases the phase interface and improves the strength and creep resistance of the titanium alloy. Meanwhile, due to the changing direction of the staggered alpha sheets and alpha clusters, the crack propagation path is tortuous, branched and resistant, and the alloy fracture toughness is high.

[0003] However, in the forging process, the titanium alloy forgings are prone to incomplete filling and incomplete acquisition of the basketweave structure. The main reason for incomplete filling is that the ultra-high strength titanium alloy has high strength, and the deformation resistance is still large even above the phase transition point. In the traditional forging process, lubricating liquid needs to be sprayed on the surface of the die cavity to reduce the friction in the forging process and the forming pressure. However, due to the poor adhesion of the lubricating liquid, it is easy to accumulate in the die cavity, which also leads to incomplete filling of the forgings. The reason for incomplete acquisition of the basketweave structure is that the basketweave structure needs to be deformed above the phase transition point to obtain it, so the temperature of the forgings must be ensured during the deformation process. However, during the forming process, the temperature of the forgings has decreased when the blank is transferred from the heating furnace to the die. As the die gradually contacts the blank to promote the deformation of the blank, the temperature difference between the die and the forgings is large, which causes the surface temperature of the blank to drop sharply. The temperature of the forgings has decreased below the phase transition point before the deformation starts, which leads to the fact that the surface layer of the forgings cannot obtain the basketweave structure, and the structure inside the forgings is inconsistent. In severe cases, the removal amount of the machined forgings exceeds the limit, resulting in the rejection of the forgings.

[0004] Patent application No. CN113500160A discloses a forging cloth with improved titanium alloy surface structure uniformity and a manufacturing method thereof. The forging cloth includes a graphite layer, a fiber layer, an adhesive, and a thermal insulation cotton layer. The graphite layer is uniformly attached to any one plane of the fiber layer. The other plane of the fiber layer is fixed with the thermal insulation cotton layer through the adhesive. The forging cloth has a certain heat preservation and lubrication effect, which can meet the forging needs of most titanium alloys. However, for the forging of ultra-high strength titanium alloy with higher forging quality requirements, the surface temperature of the forgings still decreases a lot during forging, and the heat insulation effect of the forging cloth still does not meet the requirements.
