Hand-welded and automatically uniform welds of Sanicro 25 are evaluated in material studies, and the structure and basic mechanical properties of welded joints are examined.
Microstructure and hardness properties.
These factors had a significant impact on the relatively low strength and ductility of the joint.
The hardness of the weld joint did not exceed 210 HV, and showed good mechanical properties.

The key factor affecting the penetration increase is the interaction between the assisted gas jet and the plasma.
The microhardness of welded joints can indirectly reflect their mechanical properties, and microhardness is mainly determined by the microstucture and grain size.
Another factor affecting the penetration increase of gas-jet-assisted keyhole laser welding is the shape and spatial distribution of the keyhole.
Many factors affect the spatial distribution of the keyhole, including the laser wavelength, focal spot size, laser power, welding speed, defocusing distance, and material parameters.

Researchers are attempting to improve the properties further with the addition of another fiber in the same matrix (hybridization).
The cutting tool material and the geometry also play a vital role in affecting the thrust force and delamination as reported in [3].
Reference [4] shows that there is an enhancement in the flexural and tensile properties because of the addition of nanotubes.
Though all interactions between the factors significantly affecting the delamination, maximum contribution of 17.30% was observed with the interaction between cutting speed and feed rate.
From Table 5, the mean grades of various factors at chosen levels can be observed.

Federici et al.[3]demonstrated that the thermal properties of reactor materials play a vital role in the overall thermal stability of micro-reactors.
To extend the operation range and to study the interplay of methane/moist air reactions in microchannel-reactors, this paper simulated the methane/moist air catalytic combustion with fluent software in mirochannels with different wall shapes and analyzed the impact of different surface shape factors on the methane/moist air catalytic combustion .
Numerical Model and Chemical Mechanical Physical Model.
This is because the groove in the microchannel increased wall roughness, thereby affecting the residence time of the combustion gas.
A single groove on the overall average mass fraction of each component is not affected.
