Contributions of Grain Boundary and Volume Diffusion to Shrinkage Rates during Sinteringd volume diffusion and grain boundary diffusion separately. In the present model the uniform shrinkage condition at the grain boundary is applied to the sum of the volume and grain boundary fluxes rather than to each flux separately. The assumption of the earlier models that each flux provided unifoParley 发表于 2025-3-25 12:37:48
A Kinetic Model for the Reduction in Surface Area during Initial Stage Sinteringse calculations have provided the first precise relationship between neck size and the specific surface area based on a minimum surface energy consideration in a sphere-to-sphere configuration. Also, shrinkage in particle size or interparticle distance has been directly related to the neck size for先兆 发表于 2025-3-25 17:11:49
The Identification of the Initial-Stage Sintering Mechanism: A New Approache initial stage sintering of monosized spheres. It was shown that such a relation is dependent on both mechanism and particle coordination (powder packing fraction) in the following manner:.Here ΔS/S. is the normalized specific surface area reduction; t is the isothermal sintering time; B is a constVenules 发表于 2025-3-25 21:25:10

Transmission Electron Microscopy — Some Techniques Useful in Sintering Studiesications to standard technique. It is the purpose of this communication to describe these modifications, to illustrate application with several examples, and to outline an approximation which can be useful in interpretation.称赞 发表于 2025-3-26 06:06:28

Sintering Retardation in Catalyststed alternatively as an equilibrium fine particle size due to strain energy (1) and maintenance of particle size through a reduction in sintering kinetics (7). A third possibility, intermediate between these two, has been proposed recently (8) and will be discussed below.强所 发表于 2025-3-26 20:05:46
