Fig. 6: Surface transversal residual stresses across the welds of sheets There are some other factors which may affect the fatigue resistance characteristics like e.g. different notch toughness, but the most important probably are residual stresses, evaluated by X-ray diffraction at the Czech Technical University in Prague – Fig. 6.
Conclusions Very different and self- contradictory results of the investigation of fatigue resistance of laser welded sheets of 6 mm and 10 mm thickness, respectively were found and some possible affecting factors like local microstructure, chemical composition, local hardness and residual stresses were addressed.

The room temperature and 600°C tensile properties were tested on ENST-1196 test machine, and the properties data were the mean value of two tested samples.
So the forging temperature and heat treatment are the central factors which affect the volume fraction of primary α phase.
Tensile Properties.
The samples isothermally forged at different temperature have different tensile properties, as shown in Fig. 5.
Fig. 5 Tensile properties of TG6 isothermal forgings: (a) at RT, (b) at 600℃ The majority of phases in TG6 alloy are α phase after the heat treatment (1015°C, 2h, AC + 700°C, 2h, AC) because of the low content of the β stabilisers, so the tensile properties are affected mainly by the morphology and distribution of α phase.

In general, the mechanical material properties are strongly temperature-dependent [15][16].
In the next section, mechanical material properties are presented for the dual-phase steel grade DP600.
The elastic and thermal properties have been taken from [10].

Simulations have been performed to give some indications about which factors affect the accuracy of the model.

Introduction Laser cladding is a rapid solidification process, by using high-energy density laser beam and rapid melting the different materials on the substrate surface, forming the metallurgical bond layer with completely different composition and properties.
There are cracks and other defects on the cladding layer which using a single ceramic powder, while a single Ni-based powder coatings has been difficult to achieve high wear resistance, high hardness and other properties.
The quality of laser cladding layer depends largely on the cladding layer microstructure and mechanical properties, so it is particularly important to explore the influence of the laser process parameters (laser power, scanning speed, etc.) microstructure and micro-hardness of layers, and then control them [3].
Powder Preparation: 5% ZrO2 and 95% Ni60A powder were mechanical mixed, and baking.

The elastic property of the film is one of the key factors influencing performance of the coating.
With the change of the static force and the specimen elasticity, contact stiffness will change, and the results show that the atomic force acoustic microscopy techniques can effectively measure the elastic properties of the sample.

It is well-known that the mechanical properties of tool steel are strongly correlated with the carbides.
According to Boccalini and Goldenstein [1] the type, morphology and volume fraction of eutectic carbides were the important factors in contributing the mechanical properties of tool steels.
Peidao [3]studied the Fe-Mo-C alloys and the result showed that the as cast microstructure including carbide formation related to diffusivity of alloying elements and thermodynamic factors.
Peidao et.al [4] also found the alloy composition of the high speed steels affected the difference in morphology of eutectic carbides.

The selection of treatment methods for rising damp should be supported by an exhaustive evaluation and study of the conditioning factors to achieve a successful outcome of the treatment.
Defining the factors which may affect the success of the application are crucial, these include: material constitution, characteristics and thickness of affected building elements, the initial water content, the interior conditions of the building and its surroundings as well as the respective location.
Due to the difficulty and variability of factors, some unpredictability exists in the results.
Fields like description and characteristics, installation process, representation, properties, application and limitations were selected to best characterize the treatment.
The differences are mainly the lack of field properties in the systems, not the size.
