The influence of buoyancy-driven convection on the lamellar spacing of an Al-Zn cutectic was studied under conditions of oriented crystallization. The convection due to huoyancy was affected by the mold position respective to thc direction of action of the force of gravity. It has been found that th
current Interest In Research Of Solidification Of Melts Is Focused To Understand Crystal Nucleation And Crystal Growth. They Determine The Solidified Product With Its Physical Properties. A Detailed Description Of These Processes Lead To The Development And Validation Of Physical Models, Which May F
