On kinetics and thermodynamics of high angle grain boundaries in aluminium : experimental study on grain boundary properties in bi- and tricrystals
In this work, experimental study on grain boundary migration and grain boundary structure has been performed. The dependence of grain boundary (GB) and triple junction (TJ) migration on grain boundary character (disorientation between the grains and inclination of the boundary plane), temperature, …

Nanoscale Study of Perovskite Solar Cells for Efficient Charge Transport
… effect of temperature, humidity and water on the grain boundary potential and charge transport within the grains of pervoskite films prepared by sequential deposition technique. Grain boundary potential of perovskite films exhibited variation in electrical properties with humidity level, …

Stability of nanostructured : amorphous aluminum-manganese alloys
… incorporation level. The manganese exhibits grain boundary segregation in the Al-Mn solid solution in the as-deposited condition, which contributes to enhanced stability of the nanostructure. The grain boundary properties of the nanostructured alloys were studied via three dimensional atom …

Grain boundary studies in ordered intermetallic compound Ni3 Al
Theoretical and experimental studies of grain boundary structures were carried out to understand the grain boundary properties of Ni₃Al. Using various techniques of transmission electron microscopy, the geometry of grain boundaries was determined from a number of grain boundaries to obtain a …

Crack path selection in microstructurally tailored inhomogeneous polymers
In this work, the wide range of properties of a photodegradable polymer are exploited to generate a host of different inhomogeneous arrangements that can help us experimentally study crack path selection problems. The model material which we are using is a polyethylene co-polymer, ECO, whose …

The effects of dopants and complexions on grain boundary diffusion and fracture toughness in α-Al2O3
Grain boundaries often play a dominant role in determining material properties and processing, which originates from their distinct local structures, chemistry, and properties. Understanding and controlling grain boundary structure-property relationships has been an ongoing challenge that is …

Magnetic Detection of Microstructural Change in Power Plant Steels
… changes, which eventually degrade the creep properties, occur during the long service life. Conservative design lives are used in power plant, and it is often found that components can be used safely beyond the original design life. However, to benefit from this requires reliable monitoring …
