In conclusion, the distribution, the chemical composition and the amount of the carbides, as well as the matrix microstructure are all factors to influence the crack resistance, hardness and wear resistance of the hardfacing alloys.
Additions of these different alloying elements were to gain good mechanical and wear resistance properties.
All these have further influence on the properties of matrix.

These disadvantageous properties caused diffusion wear and shorter tool lives.
For these factors, the machining of GH4169 should been carried out at low cutting speeds with coolant recommended for cooling the tool and work-piece.
The function of the cooling air is to flush away the chips from the cutting zone (flushing effect) and reduce the cutting temperature, which are two very important and correlated factors affecting slot milling of GH4169 [6].
It is well known that the surface finish can significantly affect the mechanical strength of components when they are subjected to fatigue cycles.
Moreover, when machining of GH4169, the temperature is very high because of its unfavorable machining properties as mentioned above, and it may cause adhesion of the residual chip (or tool) particles to the machined surfaces.

In view of possible scaling up to particular industrial applications, a detailed characterization of the microstructure, morphology, physical, chemical and mechanical properties of the coatings was performed.
Ceramic materials are particularly interesting because they show excellent mechanical and heat resistance properties and tend to be chemically inert.
A detailed characterization of the microstructure, morphology, physical, chemical and mechanical properties of the coating was performed to compare the different technologies.
Anyway, the selection of the right enameling process depends on many factors and cannot be generalized.

High-strength steel is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel.
Strip shape is an important factor affecting the strip quality significantly for the rolled products.
Because of the complex influence factors of plate shape and profile, shape detection and control technology have not been solved, especially for high strength steel rolling.
Most mechanical and physical properties and boundary conditions are temperature related.

Until now, many strategies have been reported for the synthesis of silver nanowires.[3,4] The most widely used method is polyol reduction method, because it can not only avoid the post-treatment necessary for template assisted method, [5] but also omit the use of hash chemicals applied in other synthesis methods.[6] Several experimental parameters like temperature, reaction time, concentration of the reactant the exotic agents of salts as inhibitors in polyol reduction process are important factors that affect the affect the final products.

Temperature is one of the major factors affected the interface strength and formability on warm forming of multilayered sheet metal.
In this study, the mechanical properties and formability of a Mg-Al-SUS clad sheet are investigated.
Among these processes, roll bonding is the effective method due to manufacturing cost, however, it is difficult to simultaneously achieve all of the required properties and conditions such as bond strength, formability, thermal profiles in the dies, etc.
Formability is the important factor needed to deform a clad sheet into a final shape.

Creep crack initiation and growth properties are also affected by multi-axial stress and it is important to evaluate these effects when laboratory data are applied to structural components.
In order to investigate the effects of multi-axial stress on creep crack growth properties, the tests were conducted for various notch depths at 650°C.
Creep crack growth properties could be predicted by allowing for the decrease of creep ductility under multi-axial conditions.
