TL;DR: In this article, the nature of the bonding between metals and ceramics, with emphasis on ionocovalent oxide ceramic, is discussed using an electronic approach, and the general behavior of wetting and adhesion in metal/ceramic systems could be deduced.
Abstract: The current understanding of metal-ceramic interactions is presented based on wetting data obtained by the sessile drop technique. The nature of the bonding between metals and ceramics, with emphasis on ionocovalent oxide ceramics, is discussed using an electronic approach. Typical examples are given to illustrate the effect of oxygen on the wetting behaviour of a metal/ceramic system when it acts as a dissolved element in the liquid metal, and when it causes the formation of an oxide film on the metal surface and an oxide-like layer on the ceramic surface. The influence of alloying elements on the wetting properties is elucidated using a thermodynamic model. Following these discussions, the general behaviour of wetting and adhesion in metal/ceramic systems could thus be deduced.

TL;DR: A review of the state of the art in liquid metal additive manufacturing can be found in this article, where various printing modes and droplet generation techniques as applied to liquid metals are discussed.
Abstract: This review focuses on the current state of the art in liquid metal additive manufacturing (AM), an emerging and growing family of related printing technologies used to fabricate near-net shape or fully free-standing metal objects. The various printing modes and droplet generation techniques as applied to liquid metals are discussed. Two different printing modes, continuous and drop-on-demand (DOD), exist for liquid metal printing and are based on commercial inkjet printing technology. Several techniques are in various stages of development from laboratory testing, prototyping, to full commercialization. Printing techniques include metal droplet generation by piezoelectric actuation or impact-driven, electrostatic, pneumatic, electrohydrodynamic (EHD), magnetohydrodynamic (MHD) ejection, or droplet generation by application of a high-power laser. The impetus for development of liquid metal printing was the precise, and often small scale, jetting of solder alloys for microelectronics applications. The fabrication of higher-melting-point metals and alloys and the printing of free-standing metal objects has provided further motivation for the research and development of liquid metal printing.

TL;DR: In this paper, an experimental set-up allowing the magnetic susceptibility measurement during the processing of metallic alloys at high temperature in high magnetic fields is described, and results for a high-Curie-temperature Co-Sn alloy are presented, together with the effect of the field on the resulting microstructure.
Abstract: An experimental set-up allowing the magnetic susceptibility measurement during the processing of metallic alloys at high temperature in high magnetic fields is described. Curie temperature, melting and solidification can be observed by the magnetic susceptibility variations. Results for a high-Curie-temperature Co–Sn alloy are presented, together with the effect of the field on the resulting microstructure.
