The contact force is limited to the size of beam as we know by some general equations of material science.
The method how to protect the micron size contact with commercial materials has to be developed in the future.

Introduction Increased requirements for safety and performance of structural elements operating in difficult conditions, lead to the necessity of their manufacture from the most perspective materials.
Often the existence of desired structure is achieved by cooling of the material at a predetermined velocity [1].
The material properties of the billet is a functions of temperature Ts.
