Grain growth and grain size distributions in thin germanium films
TL;DR: In this paper, normal and secondary grain growth in thin films of germanium on silicon dioxide was observed and characterized, and the grain size distributions were lognormal with mean grain diameters of about 2.5 times the film thickness.

Numerical treatment of rapid solidification
TL;DR: Techniques for describing crystal nucleation and subsequent advance of the crystallization front in metallic melts under the range of conditions generated during rapid solidification processing are reviewed in this article, with particular reference to coupling between the undercooling at and the velocity of the growth front.

Freezing phenomena in ice–water systems
TL;DR: In this article, the properties of water and ice and the phase diagram of water are discussed with special emphasis on ice density, and a concise account of the freezing process and the Stefan problem is presented.
