Agarwal, G. (author), Amirthalingam, M. (author), Moon, S. C. (author), Dippenaar, R. J. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Sufficient liquid feeding under constrained solidification conditions like, those experienced in welding and casting, is vital to avoid solidification cracking. We present the results of unique in-situ experimental observations of liquid feeding in a solidifying steel melt pool. Liquid feeding was observed in the inter-cellular regions during...journal article 2018

(author)In situ high-temperature laser scanning confocal microscopy is applied to study solidification cracking in a TRIP steel. Solidification cracking was observed in the interdendritic region during the last stage of solidification. Atom probe tomography revealed notable enrichment of phosphorus in the last remaining liquid. Phase field...journal article 2018
