Compression Property Determination of a Gamma Titanium Aluminide Alloy Using Microspecimens (Preprint)

摘要

The room temperature yield behaviors under compression of micro- specimens representing three lamellar orientations of a gamma titanium aluminide alloy were evaluated. The mechanical responses from specimens of each orientation and various diameters are compared to one another and to compression-loaded, conventionally-sized titanium aluminide specimens. The yield stress results from the micro-specimens are shown to be relatively independent of specimen diameter and similar to those of conventionally-sized compression specimens.
