本研究是基于理解的想法，通过研究独立的金属膜作为一个模型系统中的泡沫金属膜的破裂。液体动力学，破裂材料的速度以及熔体内的陶瓷颗粒的行为进行了光学非原位和同步辐射X射线照相原位分析。有人发现，膜的抗破裂性主要是基于固体颗粒和不动的氧化皮之间的相互作用，其形成取决于周围大气中的氧含量和镁的存在。
The present study is based on the idea of understanding the rupture of films in metal foams by studying free standing metallic films as a model system. Liquid dynamics, the velocity of the rupturing material as well as the behaviour of ceramic particles inside the melt were analysed optically ex situ and by synchrotron X-ray radiography in situ. It was found that the resistance of films to rupture is mainly based on the interaction between solid particles and an immobile oxide skin, the formation of which depends on the oxygen content of the surrounding atmosphere and the presence of magnesium.
