Abstract:

The primary objective of this project was to develop digital computer techniques for the quantitative characterization of alloy microstructures. A secondary objective was to utilize these quantities to determine the numerical correlations between processing parameters, microstructure appearance, and mechanical properties. These objectives were restricted in scope to the 6Al-2Sn-4Zr-6Mo titanium alloy. To these ends, computer programs were written to 1 Perform separation of individual connected regions from the background in a digitized micrograph 2 compute 34 quantities which describe geometric properties of the photomicrograph and 3 correlate these 34 quantities with 8 mechanical property measurements for each of 57 alloy specimens. The results of applying these programs to 139 photomicrographs of two perpendicular views of the alloy are given. Author
