We aim to develop a sound understanding of the origins of ridge-buckle defects in flat-rolled steel sheet and to train researchers in advanced techniques. By studying dynamic recrystallisation and texture formation, not of the bulk, but of isolated pockets of material within the bulk that are subject to fluctuating conditions of temperature and stress, defect formation will be related to the intricate interplay between rolling dynamics and microstructural development. Through this new approach a scientifically founded quantitative model should emerge so that defect occurrence can be forecasted, preventative action predicted and industry's competitive position be retained.

我们的目标是发展一个良好的理解的起源，在平轧钢板的脊屈曲缺陷和培训研究人员在先进的技术。通过研究动态再结晶和织构的形成，而不是散装的，但孤立的口袋内的散装材料，受到波动的温度和应力条件，缺陷的形成将涉及到复杂的相互作用之间的轧制动力学和微观结构的发展。通过这种新的方法，一个科学建立的定量模型应该出现，以便可以预测缺陷的发生，预测预防措施和行业的竞争地位得以保持。
