These waves interact with the microstructure
, and this allows us to "see" it.
Developed jointly with the Fraunhofer Institute for Microstructure
of Materials and Systems IMWS, the MicroPrep 2.0 complements existing approaches to sample preparation such as focused ion beam (FIB) micromachining, offering up to 10,000 times higher ablation rates and therefore an order of magnitude lower cost of ownership compared to FIB.
They transmit the laser light to the tissue site and detect the fluorescence signal that is emitted back, which is turned into real-time images of the internal microstructure
1 shows microstructure
of investigated material 14MoV6-3 at transversal cross section of steamline pipe with same magnifications.
Many articles were published to study microstructure
change in directional solidification.
Refinement and the modifying effects of the Fe-rich phases were assessed by microstructure
The proposed method can potentially measure the surface of more types of microstructures
, and the measurement uncertainty can be evaluated by standard samples of the microstructure
with highly geometrical accuracy; these can constitute future work.
However, fatigue resistance frequently decreases at the weld joint of the pipes because of the strong stress concentration caused by the variation in chemical composition and microstructure
between the weld metal and base metal, as well as the remaining weld reinforcement .
The results demonstrated that microstructure
of granular bainite mixed with ferrite was with the highest charge transfer resistance and the most positive current density value.
1).They are: casting design, process selection and optimization, casting defect and microstructure
prediction, and structural performance evaluation.
The thermal history of casting process is used to predict the resultant microstructure
features (microporosity, eulectic phases, and precipitate phase); the microstructure
information is used in the prediction of mechanical property (yield strength, fatigue, etc.); the material properties are finally input into the analysis of the cast aluminum cylinder heads ami blocks to predict the residual stresses and durability.
The polymer microstructure
has important effects on the viscoelasticity of the fracturing fluid, but the relationship between the drag reduction mechanism and the microstructure
of the polymer drag reducer has not yet been directly established .
