Titanium aerospace investment casting

In this work, a Titanium aerospace investment casting was analyzed by X-ray micro Computed Tomography (X-ray microCT). The geometry cast and evaluated was supplied by Boeing, and was supplied to CSIR as a design file. This geometry is used to benchmark titanium casting processes and suppliers against aerospace standards. Key features of interest are internal …
