Computational modeling offers an opportunity for a better understanding and investigation of thermal transfer mechanisms. It can be used for the optimization of the electron beam melting process and for obtaining new materials with improved characteristics that have many applications in the power industry, medicine, instrument engineering, electronics, etc. A time-dependent 3D axis-symmetrical ...

Selective Laser Melting (SLM) is becoming very diffused in layer manufacturing processes because of the possibility to build complex 3D parts. The process is mainly suited for the production of tools and inserts with internal undercuts and channels for conformal cooling in fast injection molding cycles. Manufacturing of parts is obtained by consolidating successive layers of metal powder materi...

Abstract Artificial Intelligence has left no stone unturned, and mechanical engineering is one of its biggest consumers. Such technological advancements in metal melting can help process simplification, hazard reduction, human involvement reduction & lesser time. Implementing the AI models technology will ultimately various industries, i.e., Foundry, Architecture, Jewelry Industry, etc. Thi...

Platinum metals have long been used in the glass industry for crucibles and liners because of their high melting points and their chemical inertness to most molten glasses. Contamination of glass by platinum metals has not been reported except in one or two instances where the glasses had a high content of lead or barium. It is well known that heavy lead glasses are more susceptible to colourin...

Because of the high energies involved, giant impacts that occur during planetary accretion cause large degrees of melting. The depth of melting in the target body after each collision determines the pressure and temperature conditions of metal-silicate equilibration and thus geochemical fractionation that results from core-mantle differentiation. The accretional collisions involved in forming t...

New homoleptic and heteroleptic zinc(ii)-containing liquid metal salts with N-alkylimidazole (AlkIm) ligands and bis(trifluoromethylsulfonyl)imide (Tf2N(-)) anions are described. The general formulae of the complexes are [Zn(AlkIm)6][Tf2N]2 and [Zn(AlkIm)6-x(AlkIm')x][Tf2N]2. Single-crystal X-ray diffraction revealed that, in the solid state, the cations consist of octahedral zinc(ii) centres. ...

Mixed potential sensors were fabriated using yttria-stabilized zirconia (YSZ) as a solid electrolyte and a mixture of Au and various metal oxides as a sensing electrode. The effects of calcination temperature ranging from 600 to 1,000 °C and acid-base properties of the metal oxides on the sensing properties were examined. The selective sensing of ammonia was achieved by modification of the sens...

Stainless steels, Ni-based alloys, Ti-based and more recently high entropy alloys have been used in the aerospace industry to improve exterior properties of components coatings that require a fine surface finishing with over temperature range. High- (HEA) become ground-breaking research field provides solutions for structural/ functional materials industry. These fabricated via direct metal dep...

The preparation of amorphous nanopowders by flame synthesis opens access to common soda-lime, metal-doped glasses or bioglasses in the range of 20-80 nm and offers an alternative to conventional wet-phase preparation, solid state reactions or melting.

Grinding a 1 : 1 enantiomeric mixture of chiral transition metal complex crystals and subsequent annealing afforded crystals of a racemic compound by diffusion and rearrangement of component molecules, without melting and without racemization of each enantiomeric species.
