Abstract:
Copper-silver alloys are preferred alloys when it is desired to maintain the electrical conductivity and mechanical strength values at room temperature, at high temperatures, and where it is necessary to have higher creep strength and softening temperature than ordinary copper alloys. In this study, the effect of phosphorus content and cold deformation ratio were investigated on the mechanical properties and electrical conductivity of a copper-silver alloy which is called CuAg0.1 (CW016A).

Abstract:
Amorphous alloys have attracted considerable attention as new structural materials due to their excellent mechanical properties, high wear and corrosion resistance, magnetic properties, and electrical resistivity. However, most of them become brittle by crystallization, structural relaxation, or by separating intermetallic phases during heating. [..]

Abstract:
Many industries desire to use aluminum alloys due to their properties, including low weight, good strength properties, corrosion resistance and good castability. This growing popularity of aluminum alloys increases the requirements for their purity and hence any associated structural defects and degradation of casting properties. [..]

Abstract:
Selective laser melting (SLM) is a metal additive manufacturing technology that allows the fabrication of complex near-net-shape titanium parts. Among possible applications, titanium is important for the biomedical sector, in particular for orthopaedics due to its low elastic modulus, biocompatibility, high mechanical strength and corrosion resistance.

Abstract:
Titanium shows minimal encapsulation when implanted in bone tissue and develops a direct interfacial contact with bone. The higher surface roughness of titanium leads to a stronger anchorage in comparison with polished smooth surfaces, but the fixation is due to mechanical interlocking rather than chemical bonding.

Abstract:
The purpose of this work is to investigate the structure formation in intermetallic alloys by metallothermic reduction of oxide titanium-containing raw materials. The diagram feature of the state of the TiAl system is that a whole spectrum of intermetallic compounds is formed in it: two intermetallic compounds with wide homogeneity regions (α2-Ti3Al, γ-TiAl), two intermetallic compounds with narrow homogeneity regions (TiAl2 and TiAl3) and a number of metastable phases.

Abstract:
One of the stages of extracting gold and platinum from copper-nickel sulphide materials is their melting in electric furnaces, where the melt is separated into matte and slag. Gold and platinum are concentrated in the matte, but a significant part of them ends up in the slag, which reduces the recovery of metals. [..]

Abstract:
Among additive manufacturing technologies, robocasting emerges as a versatile and an affordable method for processing metallic materials. However, the success and competitiveness of robocasting depend on the development of easy-to-process metallic inks that do not generate residues after debinding and production of high purity metallic parts.

Abstract:
The microstructure and fatigue properties of specimens prepared using the selective laser melting technology were analyzed and compared to specimens produced of Ti6Al4V alloy by a conventional way, it means by the casting and forging. The forged samples were studied in both as-received and annealed + hot isostatic pressed conditions; the selective laser melted samples were tested after annealing + hot isostatic pressing. [..]
