WebJan 21, 2024 · Ti-3Al-2.5V alloy was usually the α phase of HCP structure at room temperature which had obvious anisotropy. During tube rolling, α grain would be influenced by stress-strain state, deformation amount, ‘Q’ ratio to result the preferred orientation and formed texture. In order to obtain radial texture tube by rolling and improve the service … WebJun 10, 2011 · Grain boundary energy anisotropy: a review After introducing the basic concepts, there is a discussion of fundamental models used to understand and predict … how many types of gear
Grain boundary energy anisotropy: a review
WebDec 1, 2024 · A three-dimensional (3D) multiple phase field model, which takes into account the grain boundary (GB) energy anisotropy caused by texture, is established based on real grain orientations and Read–Shockley model. The model is applied to the grain growth process of polycrystalline Mg (ZK60) alloy to investigate the evolution characteristics in ... WebAbstract. Abstract Energetic materials are chemical compounds or mixtures that store significant quantities of energy. In this review, we explore recent approaches to property prediction and new material synthesis. We show how the successful design of new energetic materials with tailored properties is becoming a practical reality. WebApr 13, 2024 · The interaction of martensite variants, during the progress of martensitic transformation, with grain boundaries (crystalline defect) causes a local increase in elastic energy [33]. The PS sample exhibits a higher value of stored elastic energy, which leads to a reduction in the enthalpy of the transformation measured by DSC for both direct and ... how many types of gender identities are there
