“…e results show that the centrifugal casting process with respect to gravity casting had no obvious improvements in concentrated shrinkage defects, and the gravity casting process can be more reasonable from the engineering point of view. Most of the literature [4,6,8,11,[20][21][22][23][24][25] focused on the influence of processing and simulation technology.…”

A model of investment casting of a titanium alloy gearbox based on the ProCAST software was established in this work, and the simulated result was used to optimize the casting process. The flow and temperature field of casting were simulated based on an actual pouring process. Casting defects and the solidification process were analyzed. The results show that the defects can be predicted by the simulation result exactly, and the simulated temperature field is in accordance with the actual process. Shrinkage and porosity are observably alleviated by remodelling the casting mould. The casting temperature field and solidification simulation results show that the casting defects arise from hot spots and heat accumulation. The temperature-time curve of different representative location nodes of casting further confirms the defect simulation results. In addition, the use of low-cost alloy elements reduces raw material costs. Compared with TC4 alloy, the mechanical properties of the casting remain unchanged.

“…T itanium alloys are usually used in aviation, space, automobile, and biochemical industries due to their superior performance, such as high strength, light weight, and excellent corrosion resistance [1][2][3] . At present, the working conditions of aerospace engine components are becoming more and more stringent, which put forward higher requirements for the mechanical properties, high temperature oxidation resistance and wear resistance of titanium alloys.…”

The microstructure and dry sliding wear performance of as-cast TiC p /Ti-1100-0.5Nb composite at 25 °C, 500 °C and 600 °C were systematically investigated. Results show that the solidification matrix microstructure is the typical Widmanstätten structure. The eutectic TiC particles are uniformly distributed in the matrix in the form of feathery, long rod and strip-like shapes. Meanwhile, the interface between TiC and titanium matrix is clear and without any reaction. The wear rate of TiC p /Ti-1100-0.5Nb at 600 °C and 500 °C is reduced by 95.8% and 79.9%, respectively, compared with that of the value of 51.8×10 -6 mm 3 •mm -1 at 25 °C. The friction coefficient of the steady-state period at 25 °C, 500 °C, 600 °C is 0.48, 0.8, 1.2, respectively, and the variation extent of the friction coefficient at elevated temperatures is greater than at 25 °C. The wear mechanism is changed from the mixture of adhesive wear and abrasive wear to mild oxidation wear with rising temperature. It can also be concluded that the composite possesses excellent high temperature wear resistance. The highwear resistance of the composite is attributed to the Fe 2 O 3 and TiO 2 . The presence of Fe 2 O 3 and TiO 2 reduces the wear rate, increases the friction coefficient, and also improves the range-ability of the friction coefficient.
