The effect of alloying elements on the mechanical properties is studied and a concept for design of hydrogenresistant austenitic steels is proposed.
A reason for that is the hydrogen-enhanced metallic character of interatomic bonds, which should substantially affect properties of dislocations in hydrogen-charged austenitic steels.
Mechanical properties of hydrogen-charged steels The compositions of studied steels are presented in Table 2.
The hydrogen-induced εH-martensite can be another factor affecting hydrogen brittleness.

Introduction Nodular cast iron has been an attractive kind of materials for stamping and drawing dies of automobiles because of the combination of low cost of the material, good castability and good mechanical properties[1].
To improve the properties of the ductile iron, i.e. hardness, wear resistance, surface modification by lasers [2,3,4] and electron beams [5] have been used in the industrial application.
In this study, the main factors affecting the modified layer are electric current (I), rotating speed (ω) of the work piece, contact pressure (F) and flow rate of collant (v).
And the other factors supplied the requirement for the success of the experiment.
But the other factors have little effect on the width and depth of modified layer. 2.

The flame retardation properties, mechanical properties and wear behaviors of PANOF plain weave fabrics were tested.
Results and Discussion The mechanical properties of PANOF plain weave fabrics.
As a flame retardant fabric, it must meet the required mechanical properties.
The mechanical properties of the PANOF plain weave fabrics are shown in Table 2.
The fiber is the dominate factor affecting fabric combustion properties.

Improvement of mechanical properties in Al alloys can be achieved by precipitate strengthening.
For other types of Al alloys, significant improvement of mechanical properties may result primarily from grain size refinement.
In the recent work [9], the influence of hydrostatic extrusion on the mechanical properties of 6082 aluminium alloy has been reported.
The shape factors of 'black' inclusions remain almost constant (Fig. 8a).
For the inclusions containing Si and Mg, both shape factors remain independent of the size.

Viscoelastic Properties of PVB Interlayer for Laminated Glass Structures Used in Building Reconstructions VOKÁČ Miroslav1, a *, HÁNA Tomáš1,b *, V.
This interaction depends on the properties of polymeric interlayers used in lamination process.
Interlayers exhibit the viscoelastic properties and temperature dependency usually described by the generalized Maxwell model and WLF model (Williams-Landel-Ferry).
For a reliable and economical design of laminated glass panels, the knowledge of interlayer´s mechanical properties used in these structures is fundamental.
The most important property affecting the stress-state and vertical deflections of perpendicularly loaded laminated panels, is the shear stiffness G of the interlayer.

Therefore, extensive studies have been done on the crystallographic, physical and mechanical properties of Co3Ti compound to explore the best combination of properties.
It has detrimental effect on the mechanical properties.
Investigations have been done on the relationship between microstructure and mechanical properties in binary CoAl alloys.
When these factors have been minimized, improvement in ductility has been noticed in the alloy containing L12/B2/(Co,Ni) three phases.
An increase in the volume fraction of the γ-phase improves the mechanical properties.

Electrical and Flexural Properties of Copper and Graphite Filled Phenolic Resin Composites Midan Li1, 2, a, Huan Niu1, Shoubin Wei1, Hong Yang1 1Beijing Institute of Graphic Communication, Xing Hua North Road 25, Beijing 102600, PR China 2School of Physics and Nuclear Energy Engineering, Beijing University of Aeronautics and Astronautics, No. 37, Xue Yuan Road, Hai Dian District, Beijing 100191, PR China almdjerry@sina.com Keywords: composites, electrical conductivity, flexural strength, distribution Abstract.
The particle shape is also a principal factor in influencing flexural strength.
This, however, not only increases the final cost of the material due to the high cost of the filler, but also often impairs the mechanical properties of the material.
The conductivity of composite is affected by various factors such as the volume fraction, shape and size of the conductive filler [4, 6].
