GAUSSIAN PROCESS REGRESSION APPLIED TO TWINNING ENERGIES OF MAGNESIUM
Magnesium is one of the structural materials that has a high strength to density ratio. One common problem magnesium alloys exhibit is low ductility. The underlying reason for low ductility in most magnesium alloys is that magnesium alloys assume a hexagonal close-packed (HCP) crystal structure. Plastic deformation in HCP lattices consists of energetically favorable slip on the basal planes but significantly higher energy cost on the other planes. The high aniostropy in energy cost in order to slip on different planes makes plastic deformation difficult. As a result of aniostropy in slip, a ...
