“…However, they have many favorable mechanical and electrical properties, including high mechanical strength, good wear resistance, higher hardness, superior magnetic properties, and enhanced corrosion resistance [9][10][11][12][13]. Consequently, they have attracted intensive research attention in recent years, and many Zr-, Fe-, Cu-, Ti-, Co-, Al-, Ni-, La-, and Pd-based alloys have been developed [14][15][16][17].…”

This study investigated the mechanical properties, glass-forming ability (GFA), and microstructural evolution of ZrCuAlNi amorphous alloys with various niobium (Nb) and silver (Ag) additions under static (1x10-1 – 1x10-3 s-1) and dynamic (3x103 – 5x103 s-1) loading conditions. The X-ray diffraction (XRD) results revealed that all of the alloys had an amorphous structure, and the GFA improved with an increasing Ag content. The Zr56Cu24Al9Ni7Nb1Ag3 alloy showed the highest flow stress among the various alloys under both strain rate ranges. For all of the alloys, the fracture strain increased with an increasing Ag content. Moreover, the strain rate sensitivity increased with increasing strain rate. The scanning electron microscopy observations showed that the fracture surfaces had a dimple structure. As the Ag content increased, the dimple structure changed from a smooth to molten appearance. In addition, the dimple structure density increased with an increasing strain rate. The results present that the ductility of the ZrCuAlNi amorphous alloys could be improved by increasing the Ag element content.

“…Similarly, microwaves are considered to have great potential for efficient heating of large and complex shaped solid metals, and can be integrated into manufacturing processes such as forming, welding and heat treatment. However, solid metals are microwave reflective below certain critical temperatures (around half of the melting temperatures of respective solid metals) [26]. Therefore, microwave heating had been only effectively used for heating dielectric materials.…”

Heating plays a vital role in various manufacturing processes of metallic products. Microwave heating has many advantages over conventional conductive heating methods whilst it is currently limited to heating dielectric materials and powdered metals. This paper reports a new microwave heating method using electromagnetic resonators, which was, for the first time, proved effective for heating solid metals. This is a quite promising discovery, because as known, solid metals are essentially reflective of microwaves, and thus metallic objects are often prohibited in microwave ovens. The experiment results showed almost complete microwave absorption and excellent heating performance for a range of metal plates including both magnetic (e.g., iron, nickel and invar) and non-magnetic (e.g., tin and zinc). A patterned microwave heating process was also presented by adjusting electromagnetic resonators and microwave radiations. On this basis, a new multi-zone microwave processing paradigm was developed and demonstrated for welding metal plates. The research work may not only provide potential solutions for efficient heating and processing of complex shaped metal parts, but also enable a plethora of applications like localized heating and thermal display.
