Many properties of industrial Ti–Al alloys, such as high-temperature stability of the lamellar structure and creep resistance, are determined by diffusion rates in the phases and along the interfaces. The knowledge of diffusion characteristics and fundamental understanding of diffusion mechanisms are of...

The activation energy for diffusion in metals and alloys can also be very different in different allotropes of the same system. For example, the activation energy for Ti self-diffusion and the diffusion of impurities (Al, Ga, In in Ti) changes dramatically at the α-Ti to β-Ti allotropic...
Accelerated Diffusion Phenomenon in Ti-B4C System and its Influence on the Resulting Composites 来自 掌桥科研 喜欢 0 阅读量: 11 作者:L Jia,M Hou,ZKK Zhang 摘要: Ti(O)-B4C diffusion couples and (TiC + TiB)/Ti(O) composites were prepared to study the accelerated diffusion phenomenon and ...

The present communication is concerned with the interdiffusion kinetics and the local concentration variations that take place in Ti/TiC multilayer system as a result of thermal anneals between 355 and 550°C. Within this temperature range, carbon is the diffusing species. Carbon diffuses from the...

CJT are specialists in diffusion bonding & microstructure simulation, founded by Dr Amir Shirzadi & Dr Rob Wallach out of the University of Cambridge.
The hexagonal crystal structure of aluminum oxide with the Al- and O-terminated interfaces with AlSi12 are considered. A single diffusion couple is used for each system to determine the average main and cross ternary interdiffusion coefficients. In addition, the effect of temperature and the ...
No Fe is dissolved in the Ag-solid solution, whereas the Ti concentration in the solid solution near the interface was estimated to be ∼1.0 at.%. Interaction between Ag and an equilibrated two-phase alloy with a nominal composition Fe30Ti70, consisting of FeTi intermetallic and β-Ti (...
