Abstract

The invention relates to the field of titanium alloy casting, in particular to a process for titanium alloy combined casting. The process includes the following steps of preparing of a balance weightpart; preparing of an insert; assembling of the insert; pressing of a wax pattern; preparing of a shell; pouring; and cutting. According to the process, the problem that the service life of the connecting portion between a titanium alloy casting and a balance weight is short is solved, the balance weight can be arranged in the integrally-formed titanium alloy casting in an embedded manner, and even though the casting and the insert are in incomplete fusion, the strength of the titanium alloy casting cannot be reduced and the service life of the titanium alloy casting cannot be shortened.

Description

technical field [0001] The invention relates to the field of titanium alloy casting, in particular to a titanium alloy combined casting process. Background technique [0002] Casting refers to the liquid forming process of metal materials. The molten metal is poured, injected or sucked into the cavity of the mold, and after solidification, it becomes a casting with a certain shape and performance. Cast titanium alloy refers to the titanium alloy used to cast into castings of a certain shape, and most of the deformed titanium alloys have good casting properties. [0003] Titanium castings are mostly used in vacuum shell solidification furnaces and graphite castings. Compared with deformed alloys of the same composition, their strengths are basically equal, but their plasticity and fatigue properties are about 40% to 50% lower, while the fracture toughness is slightly better. Most titanium castings are stabilized annealed. [0004] Due to the light specific gravity of titan...
