The results of many foreign and Hungarian researchers presented at the 6th International Conference on Solidification and Gravity, in Miskolc-Lillafüred, on September 2-5, 2013 have been collected in this volume. This conference series is aimed to attract all those having interest in the investigation and simulation of different types of solidification processes and both micro- and macro-gravity effects. Within the framework of the conference a MICAST meeting (Microstructure Formation in Casting of Technical Alloys under Diffusive and Magnetically Controlled Convective Conditions) was organized on September 5-6, 2013. The 2013 conference was a memorial one for Professor Hans Eckart Exner and Professor Erik György Fuchs who had died in the period between the previous (2008) and the last (2013) conference.
