Kinetics of Austenite Recrystallization during the Annealing of Cold-rolled Fe-Mn-Al-C Steel

In the current study, the recrystallization behavior of 75% cold-rolled Fe-22Mn-10Al-1.4C steel during annealing at 750, 770, 790, 810, and 830°C was studied. X-ray diffraction patterns and optical microscopy were used to characterize microstructures. The Vickers Micro-hardness test was used to characterize recrystallization kinetics during annealing. Johnson-Mehl-Avrami-Kolmogorov (JMAK) model...

Five-parameter grain boundary distribution in grain boundary engineered brass

We report the first application of a five-parameter determination of grain boundary types to grain boundary engineered alpha-brass. The most important findings were that the distribution of planes showed a prevalence of <110> tilt boundaries, especially asymmetric tilt types, and the presence of <111> twist boundaries. This distribution resulted from the low energy of these boundary types.

Formation of annealing twins during recrystallization and grain growth in 304L austenitic stainless steel

Understanding of the mechanisms of annealing twin formation is fundamental for grain boundary engineering. In this work, the formation of annealing twins in a 304L austenitic stainless steel is examined in relation to the thermo-mechanical history. The behavior of annealing twins of various morphologies is analyzed using an in-situ annealing device and EBSD. The results confirm that there is a ...

Observation of annealing twin nucleation at triple lines in nickel during grain growth

Three-dimensional near-field high-energy X-ray diffraction microscopy has been used to observe the formation of new twinned grains in high purity Ni during annealing at 800 !C. In the fully recrystallized microstructure annealed at 800 !C, twinned grains form along triple lines. Both the grain boundary character and the grain boundary dihedral angles were measured before and after the twin form...
