The titanium alloy has the characteristics of small density, high specific strength, good corrosion resistance, good biocompatibility and the like, and is widely applied to the fields of aerospace, ocean engineering, petrochemical industry, biomedical treatment and the like. However, titanium and titanium alloys have low hardness and poor wear resistance, and cannot meet the performance requirements of the special field on high hardness and high wear resistance. The titanium-based composite material also has the characteristics of low density, high specific strength, good corrosion resistance and the like, and compared with the traditional titanium and titanium alloy, the titanium-based composite material also has higher elastic modulus, more excellent wear resistance and high-temperature performance. Therefore, the low-cost high-performance titanium-based composite material plate is an excellent candidate material meeting the performance indexes such as low density, high specific strength, high elastic modulus, high hardness, high wear resistance and the like, and is oriented to the urgent demands of the fields such as aerospace, national defense military, ocean engineering and the like on high-performance metal structural materials.
However, because the reinforcing phase in the titanium-based composite material has larger differences in mechanical property, physical property and microstructure, the processing and forming of the titanium-based composite material have larger difficulty, and particularly the preparation technology of the titanium-based composite material plate is not mature enough. In the prior art, a titanium-based composite material ingot blank is mainly prepared by adopting a powder metallurgy method or a casting method, and then a hot rolling treatment is combined to prepare the titanium-based composite material plate. Patent CN113828776a discloses a preparation method of a TiBw reinforced titanium-based composite material plate, which adopts the following route: the method has the advantages that the ingot blank is prepared by powder metallurgy, the titanium-based composite material plate is prepared by multiple hot rolling and annealing treatments, but the process cost is high, the prepared plate is low in density and easy to form sintering pores, and the method totally needs to carry out 5-10 hot rolling treatments, so that the plate can absorb excessive oxygen, carbon, nitrogen and other impurity elements in the hot rolling process, and the performance of the titanium-based composite material plate is reduced. The patent CN111500957A adopts a process of smelting and casting ingot, forging and hot rolling to prepare the titanium-based composite material plate, the process needs 16-pass hot rolling, and the multipass hot rolling treatment can cause the plate to absorb excessive impurity elements in the hot rolling process, so that the mechanical property of the titanium-based composite material plate is reduced.
In conclusion, the method shortens and simplifies the rolling process of the titanium-based composite material plate, reduces the plate oxidation problem, optimizes the rolling process, reduces the process cost, and has very important engineering application value and significance.
