Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Numerical Simulations of Very Low Velocity Impacts and Ignition of an Explosive Confined by a Thin Case

Propellants, Explosives, Pyrotechnics, EarlyView.
A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

Investigation of Microscopic Nonmetallic Inclusions in Powder Metallurgical High‐Speed Steels

steel research international, EarlyView.
Methods for inclusion analysis are evaluated for suitability. Various powder metallurgical steels in different processing states are characterized. SEM/EDS data are further analyzed using analytical and statistical approaches. A thermodynamic method for determining inclusion phase composition is tested.

Development of super-solidus heat treatments for the second-generation single-crystal Ni-based superalloy ERBO/1: Experiments and 1D kinetic simulations

Journal of Materials Research and Technology
Super-solidus hot isostatic pressing heat treatments are particularly beneficial for single-crystal superalloys, which exhibit highly segregated microstructures after casting, because they not only contribute to reducing chemical heterogeneities in a ...

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...
