Movimiento de las interfases durante la solidificación horizontal de aleaciones estaño-zinc

Abstract: RESUMEN El procesamiento por solidificación es una de las rutas más importantes para producir materiales, especialmente metales y aleaciones. Los parámetros para la transformación de líquido a sólido, tales como, el gradiente de temperatura, la velocidad de crecimiento, la velocidad de enfriamiento, la velocidad de la interfase, varían de un proceso a otro y en un solo proceso también varían como una función del tiempo y de la posición. Estas variaciones junto con las diferentes composiciones de las aleaciones… Show more

“…From this graph, what is observed and given as a constant behavior in the different tests, is that where we see a minimum of the thermal gradient, Gc, the CET occurs. It can also be seen in Figure 2 that CET does not occur in a line but in a transition zone of the order of 1 cm or greater, as was reported before [23][24][25][26][27]. The values of the critical temperature gradients, Gc, are listed in Table 1.…”

“…The solidification set-up was designed in such a way that heat was extracted only through the water-cooled bottom, promoting vertical upward directional solidification. More details concerning this solidification set-up can be obtained in previous articles [23][24][25][26][27].…”
