Preferential dissolution of α phase for specimens processed less than 12 hrs were revealed by using ICP-MS (inductively coupled plasma-mass spectroscopy). Hydrides having precipitated in the α-phase at the near surface peeled off into the electrolyte, and thus resulted in reduced HUE for specimens having experienced longer charging periods. In order to increase HUE, the hydrogenation promoter, Na2S2O35H2O, was added into the electrolyte to see the effect on the hydrogen absorption.

感应耦合电浆质谱分析术(inductively coupled plasma-mass spectroscopy； ICP-MS)分析发现，渗氢前一阶段（12小时）铝元素有较明显之溶释现象，此一现象肇因於渗氢作用使近表面层α-相中析出之氢化物体积逐渐扩大膨胀，最后剥落而溶於硫酸水溶液，也因此造成长时间之渗氢效率未随渗氢时间增加而增加。

In this project, the selection criteria of matrix and reinforcement for obtaining composites with high strength and toughness are determined. The as-cast and aged microstructures of composites reinforced with particles of different strength are observed, and their metallurgical conditions and stabilization mechanisms are analyzed. The aging precipitation behaviors and mechanisms are studied. Some characteristics of nano-materials (micro-distortion areas) are found in 150nm- Al2O3p/Al composites and their formation mechanisms are expatiated. The "flexible" restriction to the deformation of the matrix by low strength AlN particle is observed by in-situ TEM and SEM techniques, and the mechanisms of its resist on cracks propagation and its contribution to composite strength are revealed. The high temperature deformation behaviors of Al2O3p/Al composites are studied. A rare-earth coating is established on sub-micron Al2O3 particles, leading to an improvement in wettability between coated Al2O3 and liquid aluminum and a decrease in infiltration pressure. The strength and ductility of coated particles reinforced composite are also increased. The interfacial characteristics, bonding structures and their formation mechanisms are studied, and the crystal orientation relationships between reinforcement particles and aluminum matrix are investigated. Finally a lighter composite with better balance of strength and damping properties is reinforced with hollow ceramic microballoons of ultra-lower strength.
