Abstract Ni60Co40 nanoparticles supported on ?-Al2O3 capable of simultaneously catalysing the steam reforming reaction methane and supplying in-situ heat necessary to activate by induction heating, have been synthesized characterized. Energy is remotely promptly supplied an alternating radiofrequency magnetic field (induction heating system) that act as dissipating agents virtue their ferromagn...

Induction cooktops are a key element in home electrification. This paper presents new use of induction cooktops, which allows the preparation infusions directly ceramic mug. It is proposed design water heater with an immersible metallic load. The dimensions load allow its embedding small vessels. Despite being smaller than conventional inductors, has specific shape that it to efficiently receiv...

Tensile viscous flow is explored as a forming method for metallic glasses in their supercooled liquid temperature region. Bulk amorphous preforms with nominal alloy composition Zr55Cu30Al10Ni5 were produced by arc melting and tiltand suction casting into a copper mould. A simple loading rig, in which the preform is suspended from a wire, combined with selective heating of the section to be defo...

The paper describes special method of parametric optimization and its application to the solution of practical engineering problems in the field of metal induction heating before hot forming operations. Numerical examples, that help to illustrate the methodology of proposed optimal control techniques, verify their validity and represent descriptions of practical applications.
