One of the promising solutions to ensure such an optimal design is the usage of magnetic particles rather than conventional inorganic structured materials as a filler.
In this regard, the implementation of a simple external magnetic field is a suitable way to tailor the macroscopic material properties and to design of ideal multifunctional nanocomposite materials composed of well-oriented fillers embedded in matrices.
Materials Polystyrene (PS) latexes were produced via an emulsion polymerization process [3].

The results of fancy yarns application did not come up to expectations, but mathematically, there are finite supplies of basic raw materials in the country, theoretically, there are very limited resources to provide and guide enterprises and designers.
Thirdly, due to lack of professional designers, and knowledge of equipment, materials and technology and as well as not having compete grasp of the influence many style elements, performance and application have greatly limited the fancy sweater.
Experimental materials:3 materials in different proportion: #1dyed fancy yarn of shorter proportion and equal circulation (4~5cm); #2longer proportion and equal circulation (12~17cm); and #3 a combination of #1 and #2 plus non equidistant dyed fancy yarn (4~5:30~33cm).

Introduction Steel is still the basic material used e.g. for machine parts.
Carbon content, combined with a properly selected amount of alloying elements, allow for long-term operation in demanding conditions [1] There are many ways to improve materials properties through various surface engineering processes, such as: application of wear-resistant coatings by carburizing [2], nitriding [3] diffusion processes as well as hard coatings produced by PVD methods [4].
Experimental The substrate material used in the study was supplied in the form of bars with a diameter of ϕ30 from which 30 mm high samples were cut.

Traditionally, when designing the extrusion die, the extrusion die is often prestressed with one or several stress rings of high stiffness materials to improve its strength.
The reason is that Bauschinger effect of materials decreases the residual stress and elastic loading capacity of the die.
Hence the pretress of the die insert is further increased because of the superimposed prestress caused by autofrettage and shrink fitting, with the advantage of materials save.
