Introduction Inventories of engineering materials from metals are decreasing, so it takes a lot of innovation to make new materials used in the engineering fields.
The process is doing by combining two or more materials in particular conditions to produce engineering materials with specific mechanical properties.
One of the example of the material used by many researchers is the polypropylene matrix which is combined with reinforcing materials from various materials.
These results are preliminary data that can be used to develop further composite materials both in terms of materials and processes, so that they can obtain better and stronger composite materials.

Dislocation interactions in Face-centered-cubic (FCC) materials There are twelve slip systems for FCC materials.
Similarly, Madec and Kubin also showed that the ternary interactions can take place in FCC materials, but reported that the ternary junctions did not have as much influence on the plastic deformation behavior as they did in body-centered-cubic (BCC) materials [3].
Together with the improvement of the prediction of the texture development, it corroborates the idea that the multi-junctions not only govern the plastic response of BCC materials but also play a significant role in the response of FCC materials.

The material removal rate of the CS-based CMP process is very low, typically less than 0.1µm/h [2].
The material removal rate was determined by substrate weight loss, assuming that material removal only occurred on the substrate surface that was exposed to the polishing slurry.
The material removal appears to be selective in regions of the material that contain invisible damage introduced during previous diamond polishing steps.
A similar selectivity of the material removal in the vicinity of substrate damage was observed as previously in the oxidizer study.

Cold forming is a method of shaping hard and brittle metallic materials at room temperature using pressure.
This machining method not only offers advantages such as a wide range of applicable workpiece materials, no restrictions on material mechanical properties, high processing efficiency, simplicity of operation, and low cost, but also produces micro-column arrays with no residual stress, no recast layer, high accuracy, and excellent structural performance [17,18].
Experimental materials and parameters.
This is because during the electrolytic alloying of steel materials, if the current density is too low, the electrochemical reaction produces oxygen, which forms a modified layer (adherent) on the machining surface.

Current research in cognitive science leads to the conclusion that 3DSM-CAD knowledge should be reconceptualised to include three types of knowledge: declarative command knowledge, specific procedural command knowledge and strategic (or metacognitive) knowledge [7].
To remove the material outside the sketch contour, the option "flip side to cut " was applied.
