Modelling twinning transitions in light metals: a new foundation for alloy and process development

澳大利亚寻求成为轻金属技术的世界领导者，但由于对镁（最轻的工程金属）和钛（最强的轻金属）的冶金行为缺乏定量了解，这一努力受到了阻碍。特别是，有穷人的知识的影响，材料参数对变形孪晶。这些知识对于高效生产和优化合金和零件设计至关重要。该提案旨在对孪晶活化中的转变进行定量理解，以改善疲劳、碰撞行为、结构完整性、成形、锻造、挤压、热轧和退火中的性能。

Australia's quest to become a world leader in light metals technology is being held back by a lack of quantitative understanding of the metallurgical behaviour of magnesium, which is the lightest engineering metal, and titanium, which is the strongest light metal. In particular, there is poor knowledge of the influence of material parameters on deformation twinning. This knowledge is vital for efficient production and optimised alloy and part design. This proposal aims to develop a quantitative understanding of transitions in twinning activation for improved performance in fatigue, crash behaviour, structural integrity, forming, forging, extruding, hot rolling and annealing.
