The advantage of this method is the elimination of weak grain boundaries and the option to align the crystal within the component, maximizing its strength characteristics along the important directions of the casting," said Lynn.
There are several microscopic methods (Forejt 2006) to obtain degree of strain in material structure, but measurement of grain boundaries deformation by means of grain boundaries orientation measurement was not used to recent time.
The alpha grain boundaries were quite regular which suggested that the material may have been cold rolled and annealed in the alpha region.
Significantly, the high-energy grain boundaries of UNCD make it possible to manufacture metallic diamond and also gives it a fracture toughness exceeding that of natural diamond.
Impurities are preferentially held at crystal grain boundaries.
The researchers then looked for other, nontoxic elements that could also collect at these grain boundaries and produce a machinable steel.
This is because the conduction in the poly-silicon channel material is ruled by grain size distribution and hampered by scattering at the grain boundaries and charged defects.
Several studies have shown that the properties (corrosion resistance, creep resistance, and fatigue crack propagation resistance) improved as the percent of special grain boundaries (3<[SIGMA]<29) increased.
The focus returns to the original physical metallurgy, and the material has been rearranged so that separate chapter deal with solidification, point defect behavior, interfaces and grain boundaries, precipitation hardening, and other matters.
Superior conductor metals with smoother surfaces minimize distortion by having fewer grain boundaries and impurities (such as oxides) at those boundaries.
On the other hand, given the experimental setting, one has comprehensive information about the orientations in grains and disorientations in grain boundaries which can be further analysed with various methods.
