This project aims to understand the response of deformation-induced products in metastable titanium alloys to external loading. Metastable titanium alloys are mechanically tuneable because they can readily twin and phase transform under load during forming or in service. This project will develop a crystal plasticity model that accounts for these deformation mechanisms. These new alloys are expected to make titanium a viable lightweight alternative for components in the aerospace and transport industries, with the weight savings helping reduce overall energy consumption.

本项目旨在了解亚稳钛合金中变形诱导产物对外部载荷的响应。亚稳态钛合金是机械可调谐的，因为它们在成形或使用过程中容易在载荷下孪晶和相变。该项目将开发一个晶体塑性模型，以解释这些变形机制。这些新合金有望使钛成为航空航天和运输行业部件的一种可行的轻质替代品，其重量的减轻有助于降低整体能耗。
