Grain Boundary Grooving at a Solid-Solid Interface,O. grain boundary grooves indicate that at high temperatures the process is controlled by diffusion of aluminum in the nickel phase. The Ni-A1.O. interfacial tension has been calculated from the kinetics constant using measured solubilities and published values of the diffusivities and it agrees wel百灵鸟 发表于 2025-3-27 11:54:33

Powder Compact Studies of Initial Sintering,ective initial length and time zero which were different from the experimental values. While these differences were small, they had a large effect on the log shrinkage-log time plot. Alumina apparently sinters by a grain boundary diffusion mechanism, with surface diffusion important at lower tempera赤字 发表于 2025-3-28 07:20:26
Densification Kinetics During Nonisothermal Sintering of Oxides,ever, a qualitative explanation based on dislocation transport of material can be proposed. This explanation rests on the premise that as the temperature is increased, the stress required for motion and generation of dislocations decreases.Hyperplasia 发表于 2025-3-28 13:12:24
