Currently developing new steel alloys requires 100s of tonnes of materials making trials slow and expensive. We have developed a high throughput approach (rapid alloy processing, RAP) to the development of new steels (spanning academia and industry) targeting an order of magnitude increase in alloy discovery. To achieve the desired formability that many applications of strip steel require (e.g. canning and automotive body panels) the crystallographic texture in the steel sheet needs to be optimised, which requires understanding of the relationships between cold deformation processing parameters and microstructural state (including strain state and texture) for cold deformation of steels. This PhD will focus on understanding the current models for texture development and build on these relationships to develop predictive models for high formability conventional steel strip grades.

目前，开发新的钢合金需要100吨的材料，这使得试验缓慢而昂贵。我们开发了一种高通量方法（快速合金加工，RAP）来开发新的钢材（跨越学术界和工业界），目标是在合金发现方面增加一个数量级。为了实现带钢的许多应用（例如罐头和汽车车身板）所需的可成形性，需要优化钢板中的晶体织构，这需要理解冷变形工艺参数与钢的冷变形的微观结构状态（包括应变状态和织构）之间的关系。该博士将专注于了解当前的纹理发展模型，并建立在这些关系的基础上，开发高成形性传统钢带等级的预测模型。
