Comparison of Structure and Properties of Hard Coatings on Commercial Tool Materials Manufactured with the Pressureless Forming Method or Laser Treatment Grzegorz Matula1, a, Mirosław Bonek1,b, Leszek A.
Investigation indicate the influence of the alloying carbides on the structure and properties of the surface layer of investigated steel depending on manufacturing conditions and power implemented laser (HPDL).
The powder metallurgy and especially employment of newer and newer forming methods, as well as modernisation of those existing so far, have led to the significant lowering of the manufacturing costs maintain very high mechanical properties of the sintered materials.
This phenomenon is the reason for the super-fast phase transformations affecting the structural mechanism of forming the surface layers subjected to laser treatment.
The best mechanical properties, including hardness and microhardness, were obtained for specimen alloyed with the 1,7 kW laser.

The results indicated that polyurethane foam modified by tung oil and starch has good thermal stability, good mechanical properties and good biodegradability.
Effect of different proportion of tung oil and starch on the properties of polyurethane foam was observed.
The mechanical properties of the samples were measured by a XWW-20CE universal material testing machine.
Effect of soil buried time on weight loss rate of PUF samples Conclusions PUF modified by an appropriate amount of starch and tung oil have better mechanical properties, thermal stability and biodegradability that pure PUF.
So the ratio of starch and tung oil is one of the key factors in preparation of biodegradable PUF, the most optimized ratio is starch/ tung oil= 3: 2.

It has been seen that electrode type is significant factor for all output parameters.
EDM electrode material must have basic properties such as electrical and thermal conductivity, a high melting temperature, low wear rate, and resistance to deformation during machining.
Electrodes used in EDM are generally fabricated by traditional mechanical machining process.
When attempting to obtain good surfaces of die with specific properties, using a special alloy as die material, such mechanical machining is difficult.
An L18 orthogonal array of Taguchi methodology was used to identify the effect of process input factors (current, duty cycle and flushing pressure) on the output factors {material removal rate (MRR) and surface roughness (SR)}.

It is well known that the air, moisture and heat transfer through the garment are the most important factors in clothing comfort [7].
Future studies will examine the properties of the socks after repeated washing and drying cycles to better understand the impact of domestic care and the change in measured properties on the end user.

Introduction The surface layer determines the functional properties of many machine parts and device elements.
A few percents of the volume of the material significantly affects the functional properties, such as abrasion, corrosion and fatigue resistance.
The technology of laser processing of materials (remelting, alloying) significantly affects the structure and properties of processed materials.
Therefore one can observe an ultra-fast phase changes/transformations affecting the structural mechanism (Fig. 6,7).

The different parameters that could affect the natural frequencies are included as factors (aspect ratio, thermal load-to-shear coefficient, ply orientation) to better perform dynamic analysis to have a good understanding of dynamic behavior of composite beams.
The constitutive relations of the laminated beam can be expressed using the generalized Hook’s law as follows [1]: (3) where: (4) And K is the shear correction factor.
The shear correction factor K is taken as 5/6.
To validate the present work, a comparison is made between our results and those taken from Ref. [5] by using the same material and section properties.

Introduction The rock massif is characterized with a high level of structural and textural heterogeneities and physico-mechanical nonstatic properties.
The initial state of rock massif stress largely depends on the stratification depth and mechanical properties of rocks.
Сhange of physico-mechanical rocks and coal properties, gases redistribution, variation of stress are observed in the faulting zones under the influence of tectonic processes.
The stress changes, which are accompanied in accordance with the properties of entire media deformation, depend on the level of initial pressure, the parameters of the voids and the deformation properties of the rock massif.
It is quite difficult to take into account changes in time over a large number of factors that affect the stress field.

After extender chain, the mechanical properties and thermal stability of PBT could be significantly improved.
After adding 20%-40% glass fiber, PBT not only can keep its original advantage, but also can greatly improve mechanical properties.
The results show that the content of LCI could affect the miscibility, crystallization and mechanical properties of PBT/PP blend.
The factors which affecting elastomer toughening are mainly related to the structure, particle size and the interface bonding strength of PBT, etc.
Generally speaking, physics, the better the mechanical performance of ABS is, the better mechanical properties of the alloy are [23].

In addition to the external factors during hot extrusion, the cracks are mainly caused by the primary MC carbides or large dimension of C particles formed due to a relatively short smelting time and large dimension of C particles during smelting with the decreasing plasticity of the grain boundary.
Hot extrusion process to produce high-grade superalloy tubes becomes one of the leading processing methods [6], mainly due to the high productivity of hot extrusion process and high mechanical properties of extruded products.
The quality of extruded tube was affect by many factors, including the high resistance of the material during hot deformation, the parameters of extrusion process, lubrication conditions and so on[7-11].
In addition to these factors above external factors during hot extrusion, the cracks are mainly generated from the grain boundaries or surfaces between the MC carbides and matrix of Inconel 625 superalloy.
