Among these, however, twinning if the only one to have been effectively applied in the thermomechanical treatment of metals and alloys to achieve grain boundary engineering.
A modified thermally controlled solidification using melt superheating treatment has been designed to an IN718C superalloy to achieve grain refinement and further improve mechanical properties.
Samples of dilute Al Mg and Al Zn alloys, containing a minor Sc addition, were processed by equal-channel angular pressing (ECAP) to achieve grain refinement and different distributions of the grain boundary misorientations.
Determining a definitive 'grain size corrosion resistance' relationship, if one exists, is inherently complex as the processing needed to achieve grain refinement also imparts other changes to the microstructure (such as texture, internal stress, and impurity segregation).
This study is carried out with the aim of achieving higher grain support for the abrasive wheel.
Processing by quasi-constrained high-pressure torsion (HPT) is important for achieving substantial grain refinement in bulk solids, but very little information is available at present on the rise in temperature that occurs in the HPT specimens during the processing operation.
A Network-on-Chip architecture partitioned into several Voltage/Frequency Islands (VFIs) is considered as a promising approach for achieving fine-grain system-level power management.
The dynamic recrystallization (DRX) rules are the significant foundation for the effective control of DRX behavior, consequently achieving fine grains and qualified microstructure in the needle piercing extrusion for AISI304 stainless steel pipe.
These suggest that large grain weigh is not a general trait in hybrid rice cultivars, but developing rice cultivars with high grain weight may be a feasible approach to achieve high grain yield.
Based on the results achieved, the grain size relative density relationship, the densification rate and the grain-growth rate were determined.
