Kinetics of Initial Sintering with Grain Growth
Journal of the American Ceramic Society, 1970Kinetic equations for initial sintering were obtained by combining the conventional kinetic equation with an empirical expression for grain growth in the initial stage. The equations describe the isothermal shrinkage of ZnO in O 2 at 80 torr and 800° to 950°C.

Effect of initial grain size on the secondary grain growth in molybdenum sheet
Materials Science and Engineering, 1984Abstract In order to understand in more detail the secondary recrystallization behaviour of rolled molybdenum sheet doped with CaO and MgO, the effect of initial grain size on the secondary grain growth behaviour was investigated using optical microscopy and X-ray diffraction.

Effect of the initial grain size on the final grain size of materials of bellows
Metal Science and Heat Treatment, 1985The final grain size of the material of measuring bellows is determined by the conditions of mechanical and heat treatment, and it depends little on the initial grain size; this makes it possible to eliminate acceptance control of the grain size of material for bellows in the state as supplied.

Grain size ratio may be crucial for the fluid initiation of martian sand grains
Icarus, 2021Abstract The active Aeolian sand movement on the Martian surface has been puzzling scientists for several decades because the existing theories do not support the initiation of sand grains under the current Martian environment. In this study, I theoretically calculated the fluid threshold (u⁎ft) for the initiation of sand grain movement by ...

Initiation of motion of quartz sand grains
1991Direct observation at a limited range of wind speeds of grain behaviour near the upwind edge of a sand deposit (by means of high-speed film) shows that disturbed grains usually, but not always, roll before taking off into reptation or saltation. Time-averaged description of the population of initial motions is deficient because of the importance of ...
