This reaction releases heat to make the reaction continue and spread to the whole reaction system in the form of the combustion wave and finally synthesizes new materials.
SHS was first to be proposed by Merzhanov, a Former Soviet Union scientist in 1967 and developed to synthesize materials in recent decades, especially in the preparation of high temperature and wear-resistant materials.
It can greatly improve the surface properties of materials, expand the field of the use of materials and provide a new way to improve the wear resistance and corrosion resistance of the workpiece.

Nitrogen mainly comes from growth ambient, air trapped in the pores of graphite parts, residual air in the growth chamber, or source materials.
Boron can originate from graphite parts and source materials.
The nitrogen and boron are believed to originate from the consumable materials used in the growth process and from the growth furnace ambient.

It is known that Gamma radiation (GR) possesses required energy and wave length to produce atomic level transformations in materials.
Thus the properties of a material can be greatly altered by irradiating these materials with adequate dose of GR [4].
Exposure of these materials to high-energy particles or radiation, results in atomic displacements, lattice damage and ionization damage which can create free charges in the material [5].
Metal acetates and nitrates were taken in stoichiometric proportions as raw materials.

These machining technologies are applied on materials and respectively for workpieces difficult or impossible to be machined by the so-called classical machining methods.
Practically, the electrical discharge determines the generation of a local high temperature which will lead to melting and vaporizing of small quantities of electrodes materials.

Introduction Conventional forging processes often offer only low performances for modern high-strength materials or PM aluminium alloys.
This and the breaking surface appearance of the tensile test specimen indicate a coarse-grained structure for these two test materials.
The tests were carried out at the Institute of Materials Science of the Leibniz Universität Hannover at 20 °C ambient test temperature.
Critical damage under uniaxial conditions denotes the general resistance of materials to ductile damage.
