Knowledge of phase transformation kinetics is a key point in designing steel grades, particular modern high-performance highly sought-after energy and transportation applications. The design space for these grades multi-dimensional given the numerous potential alloying elements. characterization techniques that are usually relied on to assess kinetics, such as metallography or dilatometry, time...

Abstract Directed energy deposition (DED) was used to produce niobium carbide (NbC)‐reinforced Ti6Al4V (Ti64) metal–matrix‐composite (MMC) structures. The objective improve upon Ti64's wear and oxidation resistance. characterization techniques consisted of scanning electron microscopy (SEM), backscattered (BSE) imaging, energy‐dispersive X‐ray spectroscopy (EDS), diffraction analysis (XRD), the...

In laser-based direct energy deposition (DED-LB) additive manufacturing (AM), wire or powder materials are melted by a high-power laser beam. Process-specific characteristics enable robust in situ fabrication of compositionally graded materials, e.g., through an adaption mass flow from independent hoppers. Based on the high flexibility this approach, pathways toward multimaterial AM have been u...

For subduction to occur, plates must bend and slide past overriding plates along fault zones. This deformation is associated with significant energy dissipation, which changes the energy balance of mantle convection and influences the thermal history of the Earth. To parameterize these effects, a subduction zone was included in a small region of a finite element model for the mantle, which also...

This Working Note follows on from the previousWorking Note 17 [Clark and Porter, 2000], to present another example of constructing scripts compositionally. This example is from molecular biology, describing how a virus passes its contents (the capsid) to a cell. The reader is referred to the previous working note for a discussion of general approach. Again, the document shows two variant formul...
