“…[1] These methods are economically beneficial and allow nanostructured materials to be obtained, for example, consolidated samples from nanometric copper powders, [2] Ni/NiAl metal-matrix composites containing up to 57 vol pct NiAl particulate, [3] new shapes of materials, [4,5] and integrally bonded composites. [6][7][8][9] These advantages make the methods suitable for a large number of technological applications.…”

The microstructure and phase composition of Al/Ti/Al interfaces with respect to their localization were investigated. An aluminum-flyer plate exhibited finer grains located close to the upper interface than those present within the aluminum-base plate. The same tendency, but with a higher number of twins, was observed for titanium. Good quality bonding with a wavy shape and four intermetallic phases, namely, TiAl 3 , TiAl, TiAl 2 , and Ti 3 Al, was only obtained at the interface closer to the explosive material. The other interface was planar with three intermetallic compounds, excluding the metastable TiAl 2 phase. As a result of a 100-hour annealing at 903 K (630°C), an Al/TiAl 3 /Ti/TiAl 3 /Al sandwich was manufactured, formed with single crystalline Al layers. A substantial difference between the intermetallic layer thicknesses was measured, with 235.3 and 167.4 lm obtained for the layers corresponding to the upper and lower interfaces, respectively. An examination by transmission electron microscopy of a thin foil taken from the interface area after a 1-hour annealing at 825 K (552°C) showed a mixture of randomly located TiAl 3 grains within the aluminum. Finally, the hardness results were correlated with the microstructural changes across the samples.

“…Therefore, the temperature increase of the powders is limited to the surface, and the thickness of the melted layer is approximately 0.5 µm, which is still relatively thin to the diameter of the powder particles. The interior of the powder particles maintains a low temperature, which will induce a cooling quenching effect on the sintered interface formed among the powder particles [19][20][21]. Compared with conventional preparation methods of amorphous alloys, this method can not only prevent the crystallization of powder particles caused by the slow cooling rate, ensuring the excellent characteristics of the metastable amorphous alloy, but can also consolidate different compositions of powders without considering the interactions between powder particles [22].…”

A Fe61Cr2Nb3Si12B22 amorphous alloy rod sample of 8.8 mm diameter has been successfully prepared through explosive consolidation. The structure and thermal stability of the as-synthesized sample have been analyzed through X-ray diffraction (XRD) and differential scanning calorimeter (DSC) analysis. The results demonstrate that the sample still retains an amorphous structure, and the glass transition temperature (Tg), the crystallization onset temperature (Tx), the supercooled liquid zone (ΔTx) (Tx − Tg) and the reduced glass transition temperatures (Trg) (Tg/Tm) are 784 K, 812 K, 28 K, and 0.556, respectively. Its microstructure has been investigated by optical microscopy (OM) and scanning electron microscopy (SEM). The average microhardness of the alumina compact is about 1069 HV.
