The effect of sulfur on the contact angle between liquid eutectic Fe-V-C alloy and VC substrate and on the microstructure of the alloy


Mario Boccalini Jr.; Alzira Vicente de Oliveira Corrêa


Abstract:

The sessile drop technique was used to evaluate the contact angle between liquid eutectic Fe-11wt%V-2.3wt%C alloy and VC substrate. This alloy solidifies through a eutectic reaction that starts at 1320°C and leads to the formation of the faceted/non-faceted austenite-VC eutectic. The effect of sulfur on the contact angle and on morphology of the austenite-VC eutectic in both non-directionally and unidirectionally solidified specimens was investigated. It was shown that sulfur increases the contact angle and modifies the eutectic morphology, thus indicating a relationship between eutectic morphology and liquid eutectic/faceted phase VC interfacial energy
