Austenite grain growth kinetics and the grain size distribution Giumelli, Alan
Abstract
The aims of this work are to assess the kinetics of austenite grain growth, and to estimate the three dimensional grain size distribution. Measurements are to be used for the validation of a statistical model for the estimation of the kinetics of austenite grain growth during hot strip rolling. A series of tests are performed with two industrial plain carbon steels in the temperature range from 950°C to 1150°C. Grain size is measured by standard manual procedures and by the use of image analysis equipment. Systematic errors in the measurements are identified. A correction is proposed to account for the systematic error in the measurement of the two dimensional grain size distribution by the use of image analysis. The kinetics of austenite grain growth are discussed and the influence of second phase particles is observed. Results are described well by a statistical model for grain growth. A number of methods for the estimation of the three dimensional grain size distribution are compared. It is concluded that the method proposed by Matsuura and Itoh is the most suitable.

The aims of this work are to assess the kinetics of austenite grain growth, and to
estimate the three dimensional grain size distribution. Measurements are to be used for the
validation of a statistical model for the estimation of the kinetics of austenite grain growth
during hot strip rolling. A series of tests are performed with two industrial plain carbon
steels in the temperature range from 950°C to 1150°C. Grain size is measured by standard
manual procedures and by the use of image analysis equipment. Systematic errors in the
measurements are identified. A correction is proposed to account for the systematic error
in the measurement of the two dimensional grain size distribution by the use of image
analysis. The kinetics of austenite grain growth are discussed and the influence of second
phase particles is observed. Results are described well by a statistical model for grain
growth. A number of methods for the estimation of the three dimensional grain size
distribution are compared. It is concluded that the method proposed by Matsuura and Itoh
is the most suitable.
