Impurities tend to segregate at grain boundaries.
Two area defects are twins and grain boundaries.
This roughness occurs on a small scale, involving grain boundaries and failure surfaces.
The results indicated that the effect of with or without grain boundary is significant to specific resistance, but the effect of quantity of grain boundaries is much smaller.
It has been demonstrated that the boron segregation at austenite grain boundaries in quenched steel is a non-equilibrium grain boundary segregation phenomena occurred during cooling.
All interfaces will reflect or scatter waves to some degree. This includes cracks, inclusions, grain boundaries and other discontinuities.
F-passivation decreased the scattering centers of the carriers and the height of the potential barriers at the grain boundaries, thus, increased the Hall mobility of the carriers.
As a result, the researchers discovered that both the physical arrangement and grain boundaries play a vital role in determining the extent of susceptibility of the metal to embrittlement.
It was revealed that the fracture of the bolt came from its poor quality including coarse grains and network-like distribution of ferrite along the grain boundaries of original austenite.
The slip in the dislocation plane produces blocking at an early stage and the uneasiness of slip at grain boundaries leads to high brittleness of the material after hot rolling.
