Ni–Ti alloy was used as brazing filler to join ZrO2 ceramics and reliable joints were achieved. The effects of temperature on the interfacial microstructure mechanical properties ZrO2/Ni–Ti/ZrO2 investigated, evolution during fracture mechanism discussed. results showed that a continuous reaction layer TiO + Ni2Ti4O formed adjacent substrate, NiTi Ni3Ti at center seam, in addition, substrate next seam converted non-stoichiometric ZrO2−x brazing. With increasing temperature, decreased...
Two steps were involved in the preparation of porous mullite ceramics: green body by foaming method combined with gelcasting, using alumina, silica and AlF3 as raw materials synthesis needle-like whiskers vapor-phase reaction. Owing to special pore structure method, crystals had enough space develop good structure. Most have diameters around 1.5 μm lengths >80 μm. By adjusting amount agent, open porosity varied from 66.3 85.5%, compressive strength flexural decreased evidently, 23.4 ± 1.8...
Reliable brazing joints of Al2O3 ceramics were obtained using an active Ni‒Ti interlayer under vacuum conditions. The microstructure and mechanical properties the studied. structural, electronic, elastic primary interfacial reaction phases determined first-principles calculations. After at 1320 °C for 30 min, Ni2Ti4O layer columnar AlNi2Ti formed interface adjacent to substrate. With increasing temperature between 1300 1380 °C, thickened gradually, became increasingly longer. As reached 1400...
The springback behavior of AHSS (Advanced High Strength Steels) is more serious than ordinary mild steels. Currently, deformations due to can be compensated by modifying the tool geometry in industry, which often consumes for a long time. In addition, stamping parts usually need welding and assembly, welded part also has deformation. Therefore, an integrated process combines presented this paper, including stamping, placing spot total 3 processes. This paper takes Ω-shaped as object study....
Aim to improve mechanical properties of the casting aluminum components, a novel process that combined squeeze with local forging was proposed. THERCAST® and FORGE® were used simulate forming automobile control arm. The effects pouring rate, temperature T6 heat treatment on microstructure evolution samples formed by this investigated. results showed rate have negligible effect those samples. could obviously refine microstructure, eliminate porosity micro-hardness. After treatment, Si...
Abstract The sintering mechanism of recrystallized silicon carbide (RSiC) is mainly “the evaporation-condensation process” carbide. In the process sintering, no liquid phase generated and samples almost do not shrink. After pore connectivity specimens comes excellent, so gas permeability RSiC porous ceramic supports very good. influences SiC micro-powder content on properties were investigated. Specifically, open porosity, cold modulus rupture, hot rupture at 1200°C, size distribution,...
In order to obtain the influences of process parameters on double-roller clamping spinning (DRCS) process, finite element (FE) numerical simulation is performed. Firstly, basis nonlinear FE analysis software ABAQUS/Explicit, model for DRCS established. Secondly, reliability verified by experiment results. Finally, using model, roller feed rate, initial wall thickness and contact length moment, maximum difference flange are studied. The results show that when rate increases, both moment will...
