Özel et al. used a four-factor two-level factorial design (24) with 16 replications to determine the effects of the cutting tool edge geometry, workpiece hardness, feed rate and cutting speed on surface roughness and resultant forces in finish hard turning of AISI H13 steel using CBN tools [2].
Abou-El-Hossein et al. experimentally studied the effect of cutting parameters on cutting force in end-milling of modified AISI P20 tool steel [3].

Parameters of the Averaged Voronoi Polyhedron are used in the presented paper for the modeling of the diffusion controlled peritectic transformation.
An analytical model of the peritectic transformation, based on the linearized concentration gradient of the solute, has been presented by Das et al. for Cd-Ag and Pb-Bi alloys [[] A.
Using the volume-averaging method Zhang at al. [[] H.

Introduction Semi-solid forming (SSF) is a forming technology invented based on the discovery of the essential rheological properties of vigorously agitated semi-solid metals by Spencer et al. [1] in 1970s, and attracted significant attention around the world.
Those clusters of small grains were identified were attributed to the solidification of large amount of liquid phase, according to the work of Püttgen et al. [11].
