Modification of Magnesium Alloys by Ceramic Particles in Gravity Die Casting

Table 1

Properties of the selected ceramic particles: misfit of the lattice parameter in closed packed planes calculated according to Turnbull and Vonnegut [3] using the crystallographic data of Villars and Calvert [4], density, and particle size according to manufacturer’s specifications.
