Image Analysis of Alpha Phase in Titanium Alloys


Metallographic and image analysis procedures have been developed to quantify stereological parameters of alpha phase microstructures in a titanium-6 aluminum-4 vanadium alloy. Metallographic etching conditions were optimized to yield acceptable and reproducible image contrast between the alpha phase and the matrix so that automatic image analysis could be performed. The automated image processing procedure which quantifies the stereological parameters of the alpha phase is described. Data from manual and image analysis methods were compared and showed good agreement. A Macintosh-based database is outlined which Integrates binary images of titanium microstructures with the corresponding titanium grade, heat treatment, and stereological parameters.
