The Origins of Spontaneous Grain Refinement in Deeply Undercooled Metallic Melts
Metals, 2014 Phase-field modeling of rapid alloy solidification, in which the rejection of latent heat from the growing solid cannot be ignored, has lagged significantly behind the modeling of conventional casting practices which can be approximated as isothermal ...

Microstructure refinement mechanism upon deeply undercooled solidification of a Ni88Cu6Co6 alloy
Journal of Materials Research and TechnologyApplying molten glass purification and cyclic superheat methods, deep undercooling treatment was performed on a Ni88Cu6Co6 alloy system. The alloy was undercooled to an undercooling as high as 300 K and the corresponding microstructure characteristics ...
