The forging process is based on the plastic deformation of a material by applying force/pressure to obtain a piece.
As a consequence, the constitutive equations of material change in these areas and as a result the yield stress also varies.
This explains the fact that the material properties in these areas are different from those in other areas of the piece.

Complete removal involves the severance of conductors and removal of jacket structure and platform materials to shore for disposal, reuse or recycling purposes.
In order to reuse any platform facilities, it requires additional considerations with respect to fatigue, material, inspection, removal and reinstallation [14].

To evaluate the compaction process of powders Fe-20Cu (wt%) and Fe-20Cu-4 diamond (wt%), it was used the Balshin[4] and Rong-De's equations [5], once it is necessary to choose the ideal zone of compaction pressure for a minimum of porosity in the system - maximum of densification, mainly for the diamond composite, because it is mandatory the determination of the ideal range of compaction for this class of material, because the use of excessive pressures causes the premature wear of the compacting matrix and general rigid parts, due to the high hardness of the diamond crystals - that causes excessive wear and in it.
In addition, it is a original paper, in the point of the view of the preparation of diamond composites of metallic matrix, without scientific data about this class of materials preparation.

At the same time, aspen wood by-products can serve as a good raw material for obtaining new value-added products.
A study of the effect of the acid concentration in the low temperature hydrolysis (1 h at a hydromodulus of 1/20) on the amount of the released extraneous materials (the water-soluble products formed as a result of wood hydrolysis) shows (Table 1) that, with growing HCl concentration, their amount in water increases.
The ammoxidation of lignocellulosic materials can be one of the promising ways of their purposeful modification due to the efficiency and relatively high yield of the end product, the simplicity of the implementation of the modification process, the low content of by-products and the use of water as a reaction medium.

Fig. 3 Polishing covering area Experimental Configuration Material of Specimen.
Based on Table 5, Abrasive material, concentration, numbers of nozzles and step over have been pooled as error to meet the level of confidence.
According to Fang et al [17, 18] and Tsai et al [19] investigations, the material removal rate depends greatly on angular rotational speed and dwelling time of nozzle scanning.
It is evident that uniform material removal over a large area with a small polishing spot exhibits enormous challenge which requires extensive scanning of micro polishing nozzles constantly over the specimen.
