BCAST is excited to announce the 4th International Conference on Advanced Solidification Processes, ICASP-4 - a conference to mark 60 years of solidification research. This conference will mark the 60th anniversary of “constitutional supercooling” (published in Acta Metallurgica 1953), which is widely regarded as the beginning of modern quantitative solidification science. There will be lots of opportunity for discussion and debate, and sixteen plenary/invited speakers and parallel sessions of oral presentations and posters over four days.
