Degradation of Hardness of Alloys from Phase Coarsening

Phase Coarsening ◽

Considerable Degradation ◽

Diffusion Simulation ◽

The hardness of alloys after phase coarsening is analyzed through the linkage between the multiparticle diffusion simulation and the finite element method simulation. Our analysis demonstrates that considerable degradation of the hardness of alloys occurs due to phase coarsening, which is related to the precipitate sizes and their distribution within the alloy. The microstructural evolution alters the manners of the nucleation, multiplication and movement of dislocations within the material, and further leads to different degradation of macroscopic hardness of alloys.

Resonant Tunneling Devices ◽

Using the finite element method, we investigate device applications of lateral resonant tunneling structures which consist of a transmission channel with attached resonators. Such structure exhibits resonance-antiresonance transmission features which may be engineered to achieve desired device properties. We show that the valley current can be reduced in such 2D lateral resonant tunneling devices, resulting in an improved current peak-to-valley ratio.
