The oxidation behabior of binary Ti-Si, Nb-Si, and Mo-Si alloys was studied over the temperature range of 700~ 1000℃ in dry air. In addition, the effect of Al addition on high temperature oxidation resistance of those alloys was also studied for comparative purpose. The results showed that the oxidation kinetics of three Ti-Si alloys at 800~1000℃ followed the parabolic-rate law, with their oxidation rates gradually increasing with temperature. This further indicates that diffusion is the rate-determining step during oxidation. It was also found that the higher the Si content the better the oxidation resistance. In addition, the scales formed on the (TiSi2)91Al9 consisted mostly of α-Al2O3, whose formation is responsible for the further improvement of oxidation resistance. The oxidation kinetics of the Nb-20Si alloy followed a multiple-stage parabolic-rate law at 700~800℃, while no-mass-gain kinetics were observed at 900-1000℃. In addition, the oxidation kinetics of the (Nb-20Si)90Al10 alloy also followed parabolic-rate law at 700~1000℃. The scales formed on the two alloys consisted of fragile, powder-like Nb2O5 structures, implying that the addition of Al can not effectively prevent the pesting phenomenon for the ternary alloy. The scales forms on MoSi2 were composed of volatile spieces of MoO3 during oxidation indicating that the pesting behavior was evident for the MoSi2 alloy. On the other hands, the oxidation kinetics of the (MoSi2)95Al5 ternary alloy followed the parabolic-rate law, indicating that the volatilization of MoO3 was significantly retarded. Based on microstructural analyses, the scales formed on the (MoSi2)95Al5 surface consisted mostly of α-Al2O3, whose formation is also responsible for the improvement of the oxidation resistance for the ternary alloy.

Abstract Intermetallic compounds based on Ni3Si (ordered fcc L12 structure) offer a number of interesting properties for structural applications in aggressive environments at elevated temperature. These interesting properties include the excellent corrosion and oxidation resistance at both ambient and elevated temperatures, good specific strength in comparison with other materials, increasing yield strength as a function of temperature, and a peak yield strength occurring at about 700℃. However, similar to the Ni3Al, binary Ni3Si suffers from grain boundary embrittlement at room temperature. Therefore, how to improve its grain boundary adhesion will be the critical point of increasing the ductility and widespread the applications of Ni-Si intermetallic alloys. According to the pre-studies, we select the Ni-19Si-3Nb alloy as the based alloy to investigate the effect of adding boron and Chromium by means of arc melting and drop casting under argon atmospheres, and then homogenizing and aging in a vacuum annealing furnace with atmosphere of 5×10-5 torr at 1080℃ for 4 hours and 700℃ for 10 hours respectively. The main part of heat-treated ingots were machined into the tensile test specimen with the gauge dimension of 3mmx2mmx20mm..Then the specimen were tensile test under different atmosphere, [such as air (14000ppm H2O vapor), vacuum(2×10-4torr),and pure water vapor(850ppm)] at different temperature(25℃、500℃、600℃、700℃、800℃). The evolution of microstructure change and mechanical properties of the Ni-19Si-3Nb-0.15B-XCr alloys were characterized by x-ray diffraction, SEM, TEM, EPMA, microhardness test, Vickers hardness test, and tensile tests. According to the result of this study. The optimum condition of the mechanical properties occurs at the composition of Ni-18Si-3Nb-0.15B-1.0Cr. It can improve elongation on high temperature due to add Cr. The elongation reaches 23﹪for the specimen tested under the vacuum at 800℃ temperature. This reason that with Cr additions the hydrogen atoms were adsorption on the alloy surface increased the possibility of adsorption of hydrogen species onto the surface. Furthermore it can form a chromium oxide layer to enhance corrosion and oxidation resistance. The results of this study showed that with Cr addition can improves ductility and suppress environment embitterment on high temperatures.

In this thesis, it is investigated the mechanical properties and microstructural evolution of Nb-Si-Ti based intermetallic alloy with different content of Hf and Mo elements. First, Nb3Si and Nb5Si3 intermetallic alloy are analyzed by an X-ray diffractometer to confirm the structure. Using the universal material testing machine and the split Hopkinson pressure bar (SHPB) to exam the quasi-static and dynamic mechanical properties of these alloys. The strain rate experiments of Nb-Si-Ti alloy with different strain rates ranging from 10-3 to104 s-1 are investigated. The experiment result show the plastic flow stress value and the strain rate sensitivity subsequently increases. Furthermore, the strength and ductility are improved by Hf or Mo element adding. With 2%Mo addtion , the Nb-Si-Ti based intermetallic alloy has the excellent mechanical properties. The microstructural evolution was observed by OM and SEM. The materials are layered and had a large Nbss phase and fine Nbss+Nb5Si3 eutectic structure. The fracture morphology show that, Nb-Si-Ti based alloys were all intergranular fracture. Typical river shapes could be seen on the surface, and many micro-cracks appeared on it.
