Multi-Phase Dataset for Ti and Ti-6Al-4V
收藏资源简介:
该数据集由华威大学的研究团队创建,旨在为钛及其合金Ti-6Al-4V的多相行为提供原子尺度的建模数据。数据集包含了α、β、ω和液态相的原子构型,并通过密度泛函理论(DFT)计算了总能量、力和应力值。数据集通过非对角超胞(NDSC)策略扩展,涵盖了振动特性和原子种类的随机替换。该数据集主要用于拟合机器学习原子间势(MLIP)模型,以准确模拟钛及其合金在广泛热力学条件下的相行为。数据集的应用领域包括航空航天、生物医学、国防和高性能工程等,旨在解决材料相变和力学性能的预测问题。
This dataset was created by a research team at the University of Warwick, aiming to provide atomic-scale modeling data for the multiphase behavior of titanium and its alloy Ti-6Al-4V. The dataset includes atomic configurations of α, β, ω, and liquid phases, where total energies, forces, and stress values were calculated via density functional theory (DFT). It was expanded using the off-diagonal supercell (NDSC) strategy, covering vibrational properties and random substitutions of atomic species. This dataset is primarily used to fit machine learning interatomic potential (MLIP) models, enabling accurate simulation of the phase behavior of titanium and its alloys under a wide range of thermodynamic conditions. Its application domains include aerospace, biomedicine, national defense, high-performance engineering and other related fields, with the goal of addressing challenges in predicting material phase transitions and mechanical properties.
