In order to evaluate the suppression ability of the developed steel for abnormal grain growth
of austenite, gear cold forging and quasi-carburizing were carried out.
To do so, microstructural crystals are placed in the mold in the direction of grain growth
desired for the entire casting.
Besides, this temperature is still lower than the onset temperature for severe grain growth
, (27) so the Al diffusion is also enhanced with the increasing temperature.
Since the nucleation of the twin-oriented domains takes place at the growth front of the crystal, the formation of the twin substructure is possible only if the grain growth
takes place in the <111>crystallographic direction.
No difference was noted between control and source:sink manipulated plants for allocation of dry matter to straw of spike at the beginning of rapid grain filling stage, but maximum straw of spike dry matter after anthesis significantly decreased after source:sink manipulation (Tables 1 and 2), indicating that glumes and awns can be effective on grain growth
during first half of seed filling period, but after this period, demand of kernel needs a stronger dry matter supporter, i.
Grain filling is also dependent on the metabolic competence of vegetative tissues, particularly of the flag leaf, in order to provide photo-assimilates to sustain grain growth
According to ESL, use of a porous alumina weight or cover plate during the manufacturing process promotes creep flattening during the initial sintering process, without the grain growth
experienced in a second firing.
Ear growth rate (EGR) and grain growth
rate (GGR) were calculated for each treatment using a construct suggested for grain growth
by Johnson and Tanner (1972).
Sugar beets and grain growth
has stopped, but warmth and sun could yet save the plants.
Figure 5 shows that during annealing at 375 K some grain growth
While nitrogen can be extracted from the soil, studies have shown that under drought conditions, nitrogen remobilisation from vegetative tissues is particularly important for grain growth
By carefully controlling temperature and timing of the heating phase, the Johns Hopkins engineers allowed about 20-25 percent of the copper's crystals to grow to a larger size in a process called "abnormal grain growth
Examples would be phase transformations, precipitation, recrystallization, and grain growth
However, heating too high will cause grain growth
in the overheated austenite, making the finished tool brittle.
Too much vegetative growth during the fall may result in excessive use of water and N, leaving insufficient resources in early summer to support grain growth
(Winter and Musick 1993).
