“…Markovsky and Semiatin used 400 kHz high frequency induction generator and variable power level of 3-5 kW for heating the Ti-6Al-4V rapidly (Markovsky and Semiatin, 2010;Markovsky and Semiatin, 2011). They could be control the heating durations within 0.1 seconds.…”

“…In contrast to using the high frequency 400 kHz (Brunelli et al, 2009) or 450 kHz (Markovsky and Semiatin, 2010;Markovsky and Semiatin, 2011) induction systems, in this study 900 kHz ultra-high frequency induction system was used for heating application of the Ti-6Al-4V alloy. Our heating frequency is approximately two times higher than the other studies on the literature.…”

ABSTRACT:This study compares an energy consumption results of the TI-6Al-4V based material processing under the 900 kHz induction heating for different cases. By this means, total power consumption and energy consumptions per sample and amount have been analyzed. Experiments have been conducted with 900 kHz, 2.8 kW ultra-high frequency induction system. Two cases are considered in the study. In the first case, TI-6Al-4V samples have been heated up to 900 °C with classical heating method, which is used in industrial applications, and then they have been cooled down by water. Afterwards, the samples have been heated up to 600 °C, 650 °C and 700 °C respectively and stress relieving process has been applied through natural cooling. During these processes, energy consumptions for each defined process have been measured. In the second case, unlike the first study, can be used five different samples have been heated up to the various temperatures between 600 °C and 1120 °C and energy consumptions have been measured for these processes. Thereby, the effect of temperature increase on each sample on energy cost has been analyzed. It has been seen that as a result of heating the titanium bulk materials, which have been used in the experiment, with ultra high frequency induction, temperature increase also increases the energy consumption. But it has been revealed that the increase rate in the energy consumption is more than the increase rate of the temperature. RESUMEN: Análisis comparativo del consumo energético de un sistema de calentamiento por inducción a alta frecuencia para aplicaciones de procesado de materiales.En este estudio se comparan los consumos energéti-cos al procesar Ti-6Al-4V por inducción a 900 kHz. Se ha analizado la potencia total consumida y la energía consumida por muestra. Los experimentos se han realizado en un sistema de inducción de ultra alta frecuencia a 900 kHz, 2,8 kW. Se han considerado dos casos, en el primero se ha calentado Ti-6Al-4V a 900 °C por el método clásico usado en la industria y enfriado en agua; posteriormente las muestras se han calentado a 600, 650 y 700 °C y enfriadas al aire para relajar tensiones. En los tres casos se midió el consumo energético. En el segundo caso, cinco muestras diferentes fueron tratadas a temperaturas entre 660 y 1120 °C, midiendo el consumo energético en todos los casos. Asimismo se analizó el efecto del incremento de temperatura en el consumo energético, observándose que al calentar los materiales de base titanio usados en este trabajo con inducción de alta frecuencia, el consumo energético aumenta al aumentar la temperatura, siendo la velocidad de incremento del consumo energético mayor que la velocidad de incremento de la temperatura.

“…the general modern trends in the creation of protective armoured ele ments consist in simultaneous achieving a high strength and hardness with sufficient characteristics of ductility of the material. A promising way to achieve this is to create multilayer (graded) structures [7][8][9], which consist either of a homogeneous chemical composition of a material, the microstructure and properties of which vary in depth, or combine essentially different in nature and mechanical properties of materials (metals, composites, ceramics) in one product to achieve the required complex of properties in general. It is well known that in order to provide sufficient impact anti-ballistic protection, armoured elements must have a high-strength and hardness of surface layer, which provides deformation and inhibition of piercing elements (bullets, shells), and deep layers with high ductility, which will prevent the cracking and destruction of the armour element.…”

titanium-based materials, which combine high strength and hardness of surface layer along with sufficient ductile characteristics of the matrix metal, are very promising for various applications, particularly, as armoured components in military-industrial complex. Above-mentioned combination of properties can be achieved by means of the creation of multilayer structures, which consist of layers possessing different physical and mechanical properties. In the present study, microstructure peculiarities, mechanical and antiballistic protection properties of the layered tibased materials are investigated. two different ways were used for fabrication of such the layered structures. the first one is a conventional metallurgical (ingotwrought) method followed by the surface rapid heat treatment of the ті-6Al-4V and t110 alloys for fabrication of graded structures with different mechanical properties over the material depth. the second one is an elemental powder metallurgy method for fabrication of the structures combining layers of the ti-6Al-4V alloy and composites based on it and hardened with tic or tib particles. ballistic tests of the obtained materials are carried out for different types of projectiles with different kinetic energy and hardness of the core; features of the penetration of the hitting elements are performed depending on the material structural state. It is proved that materials with graded and layered structures demonstrate undeniable advantages in the antiballistic protection characteristics as compared with homogeneous alloys of the same thickness.
