Physical Review Letters, 2003 We report the in situ investigation of grain growth and grain boundary migration, performed with a variable-temperature scanning tunneling microscope (STM) on a polycrystalline gold film. Atomic step resolution allowed us to identify the individual grains and, thus, also the grain boundaries.

On the Grain Growth Kinetics of a Low Density Steel
Metals, 2019 The grain growth kinetics of an age-hardenable Fe-Mn-Al-C steel were investigated. Kinetics of grain growth were determined between 1173 and 1348 K (900−1075 °C) to obtain a range of grain sizes from 30 to 475 μm.
