Grain growth, defined as the increase in volume of the average grain, is found, in its steadystate, to be directly proportional to the time of isothermal annealing. During steady-state grain growth the grain corners are found all to be quadruple points, the grain edges all triple lines and the ratio of corners to faces to edges to be 6:7:12. The rate constant for steady-state grain growth is shown to be calculable from first principles and from properties that can be measured independently of… Expand
Grain growth in zone-refined iron
Abstract The results of a detailed study of isothermal grain growth in zone-refined iron in the temperature range 550 to 850°C are presented. The empirical growth law, D = Ktn, is obeyed and the timeExpand
Effect of the Degree of Prior Cold Work on the Grain Volume Distribution and the Rate of Grain Growth of Recrystallized Aluminum
The grain volume distribution of recrystallized aluminum, determined by separating and weighing the individual grains, has been found to be log normal, its spread in size being expressed by theExpand
Microstructure and normal grain growth in metals and ceramics. Part I. Theory
By extending the theory of Feltham and combining it with the work of Rhines and Craig, a detailed statistical theory of normal grain growth has been constructed. The theory exhibits all fourExpand
Grain growth in three dimensions: a lattice model
Grain growth is the term used to describe the increase in average grain size R which occurs upon annealing a polycrystalline aggregate after primary recrystallization is complete. In the long timeExpand
A topological rationale for the dependence of grain growth on strain during superplastic deformation
Abstract A model which relates the grain growth which occurs during superplastic deformation to the amount of strain has been developed. This model relies on three-dimensional grain topology, and isExpand
Growth of silicon particles in an aluminum matrix
The growth of silicon particles in cast aluminum-silicon alloys, during isothermal heat treatment, has been studied three-dimensionally with the aid of the global parameters of quantitativeExpand
On a stochastic theory of grain growth
Abstract A theory of isothermal grain growth in polycrystalline solids, which treats grain growth as a statistical or stochastic process, is presented. In this treatment deterministic equation forExpand
Discussion of grain growth in aluminum
The data of Rhines and Craig (RC) (Met Trans., 1974, vol. 5, pp. 413-25) are partially reinterpreted. For the first regime of grain growth, average grain volume is proportional to time, in accordanceExpand
Computer simulation of grain growth—II. Grain size distribution, topology, and local dynamics
Abstract The microstructures produced by the grain growth simulation technique described in the previous paper are analyzed. The grain size distribution function is found to be time invariant whenExpand
Computer simulation of normal grain growth in three dimensions
Abstract Computer modelling has been carried out to study normal grain growth in three dimensions. The approach consists of digitizing the microstructure by dividing the polycrystalline material intoExpand


Surface tension and the sintering force in copper
The sintering force, defined as the uniaxial tensile force necessary to just stop the sintering contraction in the direction of the applied force, has been measured over the entire course of theExpand
Some fundamental ideas in topology and their application to problems in metallography
Abstract The topological ideas and results that have been used by metallurgists, together with several results not previously presented in the metallurgical literature, are developed in a systematicExpand
Measurement of Topological Parameters
The most rudimentary aspects of geometric form are those which are expressed by the topological parameters. Two of these will be discussed in the present paper, namely: (1) number of separate partsExpand
Elementary solutions of the transport equation and their applications
Abstract A new method of treating problems involving the transport equation is discussed. Starting from Van Kampen's observation that it is sufficient that “solutions” be distributions, theExpand
