The size and distribution of g¢ have important effect on the mechanical properties, especially secondary g¢.
One of their core areas of research and development is building constitutive relationships between the microstructure and mechanical properties, which provides data and foundation for optimization design and simulation of material processing [10,11].
In this paper, the effect of various g¢ microstructures on the mechanical properties will be investigated based on micropillar compression coupled with EBSD technology in a polycrystalline nickel-base superalloy, and the CRSS was also obtained.
Effect of cooling medium on g' precipitates and properties in FGH4096 alloy.
Characterization and modelling of the mechanical properties of the isolated phases in g/g' microstructure.

Another factor affecting hardness is density.
Improves casting properties or characteristics, reduces shrinkage in castings, and increases corrosion resistance.
Summary In conclusion, various duct geometries affect the product characteristics, such as the triangular duct affecting the material shrinkage of 3.68%.
The micro-photographs show that Al-Si is the dominant material in casting, so these characteristics facilitate the casting process, improve the properties or attributes of casting, reduce shrinkage in casting, and increase corrosion resistance.

Tendency of recycling industry Today, under the pressure of environmental legislation, economic and technological reasons are no longer the only factors that drive the automobile manufacturing industry and recycling industry, they are shifting toward sustainable waste management of ELV.
They also studied extrusion and molding technologies in order to make the modified recycled material meet requirements for mechanical properties, moldability, paintability and surface quality, and reduced the number of process steps and processing time.
In their observation, the recycled material showed a strong degradation in the mechanical and impact properties due to the occurrence of thermo-oxidative and thermo-mechanical degradation phenomena taking place during processing and reprocessing.
By this procedure materials with properties suitable to be reused for the same or for similar applications within the car have been obtained. 3.3.
They reached a conclusion that up to 25% foam by weight could be replaced by laminate without affecting adversely compression or fatigue properties, thereby providing a potentially useful route to recycle automotive laminates.

Introduction SCC is one of the important factors leading to the damage of pipeline steel.
The VB program is a joint form based on visual component arrangement, and add code to specify the properties and methods of assembly.
Because the default properties and methods have been part of the definition of the components, so programmers do not write much code to complete a simple program.
Results and analysis Table 1 shows the mechanical performance index gained after the test of X70 pipeline steel specimen.
Fracture is flat, and it is because the specimen is affected by the tension of principal stress direction, as shown in Fig.2 (a).

The mechanical behavior of the shock absorber shows geometry nonlinearities, material nonlinearities , load nonlinearities and contact nonlinearities[1-2]. 1.2 FEM Model 1.2.1 Material Properties Compared with a tire, the shock absorber makes a very big difference.
Fig.1 Increment of diameter with respect to a cord angle Fig.2 Increment of radius with respect to a cord modulus (2) Effects of Young’s Modulus of the fabric-reinforced rubber on the outer radius The Young’s Modulus of the fabric-reinforced rubber is also quite an important factor except that the cord angle strongly affects the performance of the shock absorber.
The analysis results demonstrate that the cord angle and the fabric elastic modulus have a great effect on the deformation, and consequently those factors will also influence the static characteristics of the shock absorber.

It also allows an analysis of the impact of various factors on the course of processes in the engine.
The properties of the end product, i.e. petrol, depend on the content of hydrocarbon groups and the applied additives.
For dozens of years, spark ignition combustion engines have been adjusted to fit the properties of different petrol types derived from crude oil, which affected the design of those engines.
Due to its properties [8, 9, 10], natural gas can be increasingly more frequently applied to fuel piston engines in cars.
Such an approach did not make it possible to fully utilise the properties of gaseous fuels, i.e.

This versatility allows us to produce components with specific material properties tailored to the intended application.[10] 2.
The layering technique may lead to the presence of micro-pores in components, potentially affecting their mechanical characteristics and structural reliability, especially in situations demanding robust strength and density.
Mechanical properties of tool steels with high wear resistance via directed energy deposition. 
Some factors affecting porosity in directed energy deposition of AlMgScZr-alloys. 

The simulation includes the calculations of temperature distribution and the mechanical behavior of the wall in fire, and the temperature calculation is the base of the latter.
In the modeling, the thermal properties for the steel and concrete such as conductivity, specific heat and thermal expansion, and the stress-strain models provided by Lie and Denham [8] are adopted herein.
It is evident that steel reinforcement yield strength does not significantly affect the fire resistance, and the fire resistance drops slightly as the steel reinforcement yield strength increases.
In fire, the temperature of steel reinforcement at the base increases dramatically and the material property degrades rapidly.

Engineering properties of Mengzi expansive soil Mengzi Town is located at latitude 23°20′, longitude 103°23′, with height 1309 meters.
The physical and mechanical indices of Mengzi expansive soil are listed in Table 1.
Comparing to expansive soil in other areas, Mengzi expansive soil has some bad engineering properties, such as higher moisture content, higher void ratio, lower density, higher plasticity and stronger shrinkage.
Also the water content which affects expansion deformation is more sensitive than the dry density.
The first three factors are the intrinsic factors of water immersion expansion deformation.

Device performance results Given the materials improved properties highlighted in the previous section, we will show in the following section how this enhanced substrate conductivity impacts the SiC power device performances.
Bipolar degradation in 4H-SiC PN diodes and SiC MOSFETs (through the bipolar body diode) has become a significant concern affecting device ruggedness.
Power module reliability of SiC engineered substrate based dies Now looking at the power module integration, the thermo mechanical properties of this new material are driving the reliability of the complete stack.
Polycrystalline SiC used as a receiver for SiC engineered substrates is driving the thermo mechanical properties of the final SiC MOSFET die and will play a crucial role on the die assembly reliability.
Our main hypothesis is that elastics and/or thermoplastics properties of the polycrystalline SiC material are modifying the lifetime model (modification of the Young modulus and/or Morrow model parameters [18]).
