Subtle changes in heat treatments of β stabilized titanium alloys have been reported to produce dramatic differences in tensile strength and ductility due to metastable phase transitions. Ideally, these changes in mechanical properties could be detected by means of a nondestructive testing technique. The relationship between bulk acoustic wave velocity and Young’s modulus is well known, but this relationship will be explored in the context of detecting subtleties of beta-stabilized titanium alloy 5553 wrought and additive manufacturing samples caused by heat treatment-induced metastable phase transitions. Conventional acoustic measurements indicate wave speed differences among a variety of heat treatment conditions and these measurements will be compared to spatial variations of properties as measured using grain orientation mapping collected with Spatially Resolved Acoustic Spectroscopy and subscale (i.e., micro, nano) indentation modulus measurements.
