摘　　要：针对喷射沉积铝合金板坯含有一定量的孔隙、直接轧制时易出现板坯表面横裂及边裂的问题,提出了一种新型的陶粒轧制工艺。研究了喷射沉积5A06,8009/S iCP铝合金板坯在陶粒轧制工艺中的轧制性能。实验结果表明,采用陶粒轧制工艺,避免了板坯轧制变形过程中裂纹的形成,有效地提高了喷射沉积铝合金板坯的轧制成形性能。A novel ceramic rolling technology was proposed for spray deposited aluminum alloy plate containing a certain quantity of porosities which easily cause transverse crack and edge crack of plate surface while directly rolling. The rolling properties of spray deposited 5A06 and 8009/SICp aluminum alloy plate during ceramic rolling process were investigated. Experimental results showed that it improved roll forming property of spray deposited aluminum alloy plate effectively and avoided cracks forming during roll deformation of the plate.
