The limited approaches have been relatively attempted for materials with hexagonal close packed (hcp) crystal structure such as Ti and Mg alloys [7-10].
However, their mechanical properties are poor among the structural materials.
Cylindrical samples of �10 mm×130 mm were prepared from the ingots, as starting materials for ECAP.
These phenomena were a contrast to the behavior of conventional materials and the ECA pressed materials.

Chen Yi and Xu Jie (2018) used the core and formation water samples of a heavy oil field in Bohai as the corrosive medium to test and evaluate the casings of different materials[6].

The growing application of CFRC composites, which are popularly known as ‘carbon-carbon’ composites in Aerospace, Automobile, Defence and other advanced industries has prompted research studies to develop drilling technology of these special materials.
CFRC composites-Fabrication and uses CFRC or C-C composites are the materials, in which Carbon/Graphite fibres are reinforced in a Carbon Matrix.
Delamination Factor {Df} It is the degree of Delamination and Delamination is a mode of failure in composite materials.
