Advanced Engineering Materials, EarlyView.Laser powder‐bed fusion (L‐PBF) can produce dense WE43 magnesium alloy parts, but their mechanical properties are limited by a nonhomogeneous microstructure. This study investigates the effects of varying direct aging (T5) and artificial age‐hardening (T6) conditions on microstructure and strength. Optimized T6 treatment significantly improves strength

Convergence of Tomlin's HOTS algorithm [PDF]
arXiv, 2012 The HOTS algorithm uses the hyperlink structure of the web to compute a vector of scores with which one can rank web pages. The HOTS vector is the vector of the exponentials of the dual variables of an optimal flow problem (the "temperature" of each page).

Advanced Engineering Materials, EarlyView.This study focuses on synthesizing equiatomic AlCuNiSi medium‐entropy alloys using mechanical alloying for advanced industrial applications. Continuous milling leads to grain refinement and the formation of stable BCC/FCC solid‐solution phases, resulting in enhanced mechanical properties. A unique Si‐rich solid‐solution phase is observed, which did not

Hot Jupiter Variability in Eclipse Depth [PDF]
, 2006 Physical conditions in the atmospheres of tidally-locked, slowly-rotating hot Jupiters correspond to dynamical circulation regimes with Rhines scales and Rossby deformation radii comparable to the planetary radii. Consequently, the large spatial scales of moving atmospheric structures could generate significant photospheric variability.

Tailoring the Deformation Behaviour of a Medium Mn Steel through Isothermal Intercritical Annealing [PDF]
arXiv, 2021 A novel concept of varying the strain hardening rate of a medium Mn steel with 8 wt\% Mn by varying the duration of the intercritical anneal after hot rolling was explored. It was found that the stability of the austenite phase showed an inverse square root relationship with intercritical annealing duration and that the maximum strain hardening rate ...

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams
Advanced Engineering Materials, EarlyView.The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.
