Summary
Grain Boundary Diffusion
is the process by which atoms move along the boundaries between grains in a
Polycrystalline Material
, often occurring at a faster rate than through the grains themselves due to the higher energy and
Less ordered structure
at the boundaries. This phenomenon is crucial for understanding
Material Properties
such as creep, sintering, and the overall
Mechanical Strength
of
Polycrystalline Material
