A new pseudo-binary Mg6Ni0.5Pd0.5 intermetallic compound stabilised by Pd for hydrogen storage

The hydrogen generation of milled Al−Li−Sn alloy in water as a portable hydrogen source was examined in the current study. The optimized alloy composition presented significant improvement in terms of hydrogen generation rate and amount, with their values respectively reaching 1137 mL g-1 min-1 and 1147 mL g-1 with an increase in Li/Sn weight ratio from 1:7 to 1:1. The efficiency of the alloy composition increased up to 99% with approximately 3.4 wt% hydrogen storage amount obtained. The XRD results indicated that the improved aluminum hydrolysis properties were attributed to the formation of the Li−Sn alloy, especially to the complex intermetallic compound Li13Sn5 produced with an increase in Li/Sn weight ratio. The Li−Sn alloy referred to an active site that acted as the initial hydrolysis center, and its hydrolysis byproduct, LiOH, can further stimulate the hydrolysis of the Al−Sn alloy.

Tangled Dislocation

Ti3Al is an ordered intermetallic compound having the DO19-type superlattice structure. The compound exhibits very limited ductility in tension below 700°C because of a pronounced planarity of slip and the absence of a sufficient number of independent slip systems. Significant differences in slip behavior in the compound as a result of differences in strain rate and mode of deformation are reported here.Figure 1 is a comparison of dislocation substructures in polycrystalline Ti3Al specimens deformed in tension, creep, and fatigue. Slip activity on both the basal and prism planes is observed for each mode of deformation. The dominant slip vector in unidirectional deformation is the a-type (b) = <1120>) (Fig. la). The dislocations are straight, occur for the most part in a screw orientation, and are arranged in planar bands. In contrast, the dislocation distribution in specimens crept at 700°C (Fig. lb) is characterized by a much reduced planarity of slip, a tangled dislocation arrangement instead of planar bands, and an increased incidence of nonbasal slip vectors.

Compound Tial

In order to improve the mechanical properties of an intermetal1ic compound TiAl, a composite material of TiAl involving a second phase Ti2AIN was prepared by a new combustion reaction method. It is found that Ti2AIN (hexagonal structure) is a rod shape as shown in Fig.1 and its side surface is almost parallel to the basal plane, and this composite material has distinguished strength at elevated temperature and considerable toughness at room temperature comparing with TiAl single phase material. Since the property of the interface of composite materials has strong influences to their mechanical properties, the structure of the interface of intermetallic compound and nitride on the areas corresponding to 2, 3 and 4 as shown in Fig.1 was investigated using high resolution electron microscopy and image processing.
