·使用SPD制备具有结合的氧化铝颗粒的Al样品。·实现了超过十倍的晶粒尺寸减小。·随着晶粒尺寸的减小，硬度增加。·样品对纯铝表现出优异的热稳定性。采用不同的剧烈塑性变形方法制备了含氧化铝颗粒的块体铝试样。对不同初始厚度的铝箔进行不同应变量的冷轧，并通过高压扭转（HPT）对铝粉进行固结和变形。在加工过程中，来自箔或颗粒表面的氧化铝颗粒容易掺入并分散在块体材料中。研究了这些氧化铝颗粒对显微组织和力学性能的影响。
• Al samples with incorporated alumina particles were prepared using SPD. • A grain size reduction by a factor over ten is achieved. • Accompanied with grain size reduction, the hardness increased. • The samples exhibit excellent thermal stability for pure aluminium. Bulk aluminium samples containing alumina particles have been produced by different severe plastic deformation methods. Aluminium foils with different initial foil thicknesses were cold rolled to different amounts of strain and aluminium powders were consolidated and deformed by high pressure torsion (HPT). During processing, alumina particles from the foil or particle surface are easily incorporated and dispersed in the bulk material. The influence of these alumina particles on the developing microstructures and the mechanical properties has been studied.
