The critical pressure and impeding pressure of Al evaporation during induction skull melting processing of TiAl

“…2000 K: P crit ϭ 3.72771 Ϫ 0.26416 X ϩ 0.00519 X 2 [13] In the regression, the correlation coefficient is above 0.99.…”

“…Figure 4 shows the relationship between the evaporation loss rate From Eqs. [9] through [13], using melt temperature, T as an independent variable, and corresponding constants in the of Al in the molten Ti-45Al(at pct) alloy and the chamber pressure at different melt temperatures. Figure 5 shows the equations as dependent variables, A, B, and C can be given out in a second-order polynomial regression: effect of chamber pressure on the evaporation loss rate of …”

Modelagem Matemática e Simulação Numérica em Dinâmica dos Fluidos.

“…No últimos dez anos, os problemas que envolvem o acoplamento de escoamento de fluidos e ondas eletromagnéticas têm sido estudados utilizando-se a tecnologia MHD ("Magnetohydrodynamic") (ver, por exemplo, [42] ou [53]). Há várias aplicações dessa tecnologia: a qualidade do aço tem sido melhorada em função de pesquisas nessa área; pode-se remover por meio de campos eletromagnéticos as inclusões não metálicas e bolhas de gás nos interstícios de metais.…”

Experimental study of natural convection in a glass pool inside a cold crucible induction melter

“…The Cold Crucible Induction Melting (CCIM) process, also known as Induction Skull Melting (ISM) process, is widely used to produce high purity melts of a range of difficult to melt materials, including Ti-Al alloys for aerospace applications, high temperature superconducting materials and silicon for electronic applications, corium (a mixture of UO 2 and ZrO 2 ) for nuclear reactor applications etc. Experimental investigations of cold crucible induction melting of metals were carried out by many researchers in order to study various aspects of design and operation of such systems [3][4][5]. Similar studies for melting non-metallic, refractory materials were also reported in the open literature [6][7][8].…”
