Ag-Cu solid solutions prepared via ball milling process were subsequently milled for 30 h and investigated by X-ray diffraction technique for Cu-20%Ag, Cu-3.64%Ag and Cu-80%Ag. It was noted that the solid solubility level increased by increasing initial solute content in composition. Results showed peak positions of silver and copper changed with milling time. By heating up to 700 K, ...

foam injection is becoming a standard conditioning agent when tunnelling with an earth-pressure balanced shield, resulting in an increasing interest in this technique. the technique is mostly based on empirical rules and experience. to be able to determine what foam and how may foam has to be injected for different soils, it is necessary to know the mechanical parameters of the foam-water-soil ...

The response of structure under shock is very important. For sandwich structures, the foam other material with good energy absorbing capacity an effective way to enhance ability resist external shock. In this work, numerical analysis conducted for double-layered plate foamed aluminum. deformation process firstly studied in case initial velocity 8.9m/s, then comparative on influence different st...

In order to study the anti-penetration mechanism of composite structures and influence foamed aluminum on performance structures, two were designed processed. Penetration tests carried out finite element models established correctness verified. The results show that has a cushioning effect can reduce ceramic damage. However, cannot provide support for deformation Kevlar, which leads shear damag...
