Solid-state transformations involving quasicrystals

Materials Science and Engineering: B, 1995
Solid-state transformations involving quasicrystals were studied in several aluminium-base ternary alloys. An ordering transformation of the icosahedral phase at room temperature was noticed. A transformation from higher symmetry of quasicrystals results in several orientational variants of the product phase, the total symmetry of which is the same as ...

Dual Mode Control Scheme for DAB Based Solid-State Transformer

IEEE transactions on power electronics
This article proposes a dual mode control (DMC) scheme for a dual active bridge based solid-state transformer. Under this control scheme, a control path is developed to achieve zero voltage switching (ZVS) and minimize peak transformer current for the ...

AC solid-state transformer using DC-DC converters and without added rectifier and inverter stages

Applied Power Electronics Conference
Solid-state transformers (SSTs) typically use several power electronic stages - a front-end rectifier, followed by a high frequency transformer-isolated DC-DC converter, and then an inverter.

Middle Frequency Transformer Investigation for Solid-State Transformer

2018 International Conference on Smart Grid (icSmartGrid), 2018
This paper investigates the middle frequency transformer for the solid-state transformer. It is expected to be used in the traffic and power system. One of the key technologies is the solid-state transformer. The 3kHz, 5kVA transformers with some different core materials are manufactured.

Solid-State Transformations

2016
Abstract Eutectoid and peritectoid transformations are classified as solid-state invariant transformations. This article focuses primarily on the structures from eutectoid transformations with emphasis on the classic iron-carbon system of steel. It reviews peritectoid phase equilibria that are very common in several binary systems.

Solid State Phase Transformations

2004
The crystal structure of a metal is not necessarily stable at all temperatures below the melting temperature. This is due to the fact that the solid always assumes the crystal structure with the lowest Gibbs free energy, even if there are other crystal structures with a slightly higher free energy.

Kinetics of polymorphic solid-state transformations

Journal of the Chemical Society, Faraday Transactions 2, 1984
Solid-state polymorphic transformations can have a profound influence on the processing and storage of some crystalline powders. Using classical models of nucleation and growth a framework is developed which highlights the importance of crystal size on the transformation rate.
