Loading scheme, tool used, friction conditions, etc. can affect the process of plastic deformation of the processed material in different ways.
This is due to the peculiarities of sliding friction at the contact of the tool being processed material and the presence of a pulling force applied to the front end of the wire during plastic deformation.

As for isotropic materials, on the assumption that their Physical-property parameters (such as k, ρ, c.etc) are constant, Fourier heat conduction equation [5] in cylindrical coordinates can be expressed as
(6)
where T is the temperature(℃) ,k the coefficient of heat conduction for isotropous materials(W /m·℃) ,ρ the mass density( kg/m3 ) ,c the specific heat(J /kg·℃),and t is the time(s)
The equation (6) is simplified in the light of symmetry condition and the coefficient of heat conduction varying with temperature is taken into consideration.

Introduction
Due to their good mechanical and physical properties, cobalt-diamond composites can be used as
cutting tools for machining of mineral materials.
This previous work also showed that the compressive stresses are lower in the matrix of composites than in pure cobalt material.

MD simulations were performed with
commercial software (Fujitsu, Materials
Explorer Ver. 5) based on the plastic crystal
model (PCM) [5].
The Pd0.4Ni0.4P0.2 alloy was created by the following two steps: rapid quenching and subsequent structural relaxation that correspond to and relaxations [14] of glassy materials, respectively.
