Static and Dynamic Interpretation of Titanium Alloy Photomicrograph Features.
Abstract
Computer and hand generated geometrical data from Ti-6Al-2Sn-4Zr-6Mo photomicrographs were statistically treated to establish family groupings of certain physical properties. These families, established by duration and freepath distribution functions, define various statistically different packets of mechanical properties which correlate to various degrees with other measured geometries. Following an Air Force Materials Laboratory (AFML) specification of an acceptable mechanical property profile, ten qualifying samples were additonally subjected to analyses sensitive to particle mass and spatial placement. Two novel methods, autocorrelation of particle mass equivalents and a stroboscopic pattern detection technique, indicated the interrelations of spatial distribution patterns and the properties of ductility, fatigue resistance, toughness, and crack propagation.
