Ultra-high-temperature ceramics are being investigated for future use in aerospace applications due to their superior thermo-mechanical properties, as well as their oxidation resistance, at temperatures above 2000°C. However, their brittleness makes them susceptible to thermal shock failure. As graded composites, compo...

The Fused Deposition Modeling process uses hardware and software machine-level language that are very similar to that of a pen-plotter. Consequently, the·use of patterns with poly-lines as basic geometric features, instead of the current method based on filled polygons (monolithic models), can increase its efficiency. ...

Volume averaging artifacts in medical imaging result from voxel occupancy by more than one tissue type and, with anisotropic voxels, may be decreased by changing the imaging plane orientation relative to the target tissue and/or by decreasing slice thickness.1 In craniofacial CT imaging, volume averaging artifact becom...

Infiltration of powdered metal parts made by SFF processes enables densification with negligible dimensional change, but typically uses a dissimilar infiltrant material resulting in poor corrosion resistance, machinability, and a heterogeneous composition inconducive to certification for critical applications. A new ap...
