“…Rapid solidification technology is a rapidly advancing field, and unique microstructures of metallic alloys and ceramics have been created [ 15 , 16 , 17 , 18 , 19 ]. Shock consolidation (SC) is a unique technique, using a shock wave generated by explosion or impact, shows considerable promise for producing bulk material from powders [ 19 ].…”

High entropy alloys (HEAs) are usually fabricated using arc melting which has the disadvantages of diseconomy, and the limitations in the shape and size of final products. However, recently, quite a large amount of research has been carried out to find the fabrication techniques for HEAs with better properties such as mechanical alloying and rapid solidification. In this paper, an AlCoCrFeNi high entropy alloy was successfully fabricated by the shock consolidation technique. In this method, the starting powders were mixed by mechanical alloying and then the shock wave was imposed to the compacted powders by explosion. High levels of residual stress existed in samples fabricated by the shock consolidation method. Due to this, after fabrication of the sample, heat treatment was used to eliminate the residual stress and improve the mechanical properties. The microstructure of the samples before and after heat treatment were examined by XRD, SEM and electron backscatter diffraction (EBSD). The shock consolidated sample and sample with heat treatment both showed the nano-structure. After heat treatment the hardness of the sample was decreased from 715 HV to the 624 HV, however the failure strength increased, and as expected the ductility of the sample was improved after heat treatment.

“…Wang utilized explosive consolidation to prepare a dense, high-volume Al 2 O 3 rod with nanostructures [23]. Farinha et al successfully synthesized two different sizes of stainless steel powders and produced crack-free blocks through explosive consolidation [24]. In this paper, based on the high strength of Fe-based amorphous alloys and the wide application prospect in functional materials, the investigation of explosive consolidation of amorphous powders is carried out to explore the explosive consolidation process of a large-sized Fe-based amorphous alloy.…”

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.
