Grain Size Effect on the Hot Deformation Processing Map of AISI 304 Austenitic Stainless Steel
In this study, the hot deformation processing map of AISI 304 austenitic stainless steel in two initial grain sizes of 15 and 40 μm was investigated. For this purpose, cylindrical samples were used in the hot compression test at the temperature range of 950-1100 °C and the strain rate of 0.005-0.5% s-1. At first, the relationship between the peak stress and Zener-Hollomon parameter w...
متن کاملEvaluation of the Austenitic Grain Growth by Thermoelectric Power Measurements
The influence of the deformation grade on the recrystallised grain size has been studied in the AISI 304 stainless steel. Therefore, cold rolled samples of this material with reductions varying between 30% and 80% were annealed at different temperatures and subsequently quenched. The mean austenitic grain sizes were measured and compared. Moreover, the correlation between the variation of the t...
متن کاملInfluence of Annealing Treatment on the Formation of Nano/Submicron Grain Size AISI 301 Austenitic Stainless Steels
Nano/submicron austenitic stainless steels have attracted increasing attention over the past few years due to fine structural control for tailoring engineering properties. At the nano/submicron grain scales, grain boundary strengthening can be significant, while ductility remains attractive. To achieve a nano/ submicron grain size, metastable austenitic stainless steels are heavily cold-worked,...
متن کاملGrain size, size-distribution and dislocation structure
Diffraction peak profile analysis (or Line Profile Analysis, LPA) has recently been developed to such an extent that it can be applied as a powerful method for the characterization of microstructures of crystalline materials in terms of crystallite size-distribution and dislocation structures. Physically based theoretical functions and their Fourier coefficients are available for both, the size...
متن کاملOptimal Grain Size Computation for
In this paper, we present a method for overlapping communications on parallel computers for pipelined algorithms. We rst introduce a general theoretical model which leads to a generic computation scheme for the optimal packet size. Then, we use the OPIUM 3 library, which provides an easy-to-use and eecient way to compute, in the general case, this optimal packet size, on the column LU factoriza...
