If prior austenite undergoes abnormal
grain growth, the fatigue strength of steel has been reported to deteriorate compared to the case of no abnormal
grain growth 7).
Modelling of austenite
grain growth kinetics in a microalloyed steel (30MSV6) in the presence of carbonitride precipitates, Philos.
2007) and is also related with the
grain growth inhibition caused by the presence of secondary phase precipitates in the grain boundaries.
2]-Y-TZP sample could be attributed to the resistance of the material to crack propagation and also the
grain growth [27].
Heat treatment at 800 [degrees]C for different times: 4, 6 and 8 h enhanced the atomic mobility and caused the
grain growth to result in a better crystallinity.
Recrystallization and
grain growth are mechanisms that alter the microsctructure of a material without necessarily altering the phase.
Hence, the pattern of
grain growth was studied in all the three varieties by sampling grains from individual spikelets from mother shoot in three different segments of spike (proximal, middle and distal) and all the bold and small grains from spikelet were grouped separately.
Grain growth during liquid phase sintering of the WC-Co alloys can be described as an Ostwald ripening process [24].
The typical [metalcaster] doesn't have the knowledge of the solidification and
grain growth.
According to Jiang Gaoming, a leading researcher at the Chinese Academy of Sciences,
grain growth will not last long if the government fails to take timely and effective measures, as the soil is already too poor to support high-yield crops.
Therefore, for the SMAT sample, the volume fraction of GBs decreases with
grain growth along the depth.
Apparently we're seeing early
grain growth where new stars and solar systems are forming, or are about to form.
