Powder Metallurgy Preparation of Metastable β Ti–Cr–Ge Alloys for Medical Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This study develops metastable β Ti–Cr–Ge alloys using powder metallurgy for biomedical implants. The Ti–10Cr–2Ge alloy exhibits superior mechanical performance with high yield strength (>1100 MPa), low Young's modulus (<85 GPa), and excellent strain hardening behavior.

The unidirectional Hotelling model with spatial price discrimination [PDF]

open access: yes
The unidirectional Hotelling model where consumers can buy only from firms located on their right (left) is extended to allow for price discriminating firms and a general class of transportation costs.

The Brexit Game: Uncertainty and Location Decision

open access: yesSSRN Electronic Journal, 2019
This article aims to analyze the strategic decision about firms location choice faced with the uncertainty surrounding Brexit. We combine Evolutionary Game Theory (EGT) and spatial Agent-based Simulation (ABS) approaches with input-output analysis.

Titanium‐S23: A New Alloy with Ultra‐High Tensile Toughness Directly from the Solid‐State Processing of Recycled Ti–6Al–4V and Ti–5Al–5Mo–5V–3Cr Powders using Field Assisted Sintering Technology

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores combining two existing aerospace titanium alloy powders, processing them via field‐assisted sintering technology and the subsequent discovery of a novel alloy composition, termed S23, with ultra‐high tensile toughness. Fine‐scale alpha precipitates favorably form in the alloy despite the relatively slow cooling, providing an ...

A Location Game On Disjoint Circles [PDF]

open access: yes
Two players are endowed with resources for setting up N locations on K identical circles, with N > K>= 1. The players alternately choose these locations (possibly in batches of more than one in each round) in order to secure the area closer to their ...

Me, us and them: evaluation of cooperation and competition in a location-based serious game design [PDF]

open access: yes, 2014
Introduction Parallel to the growing interest in the deployment of digital games as an instructional tool for educational and social purposes and their theoretical underpinning and viability (Egenfeldt-Nielsen, 2006), the social aspect of gaming itself ...

Investigation of Iron‐Aluminide‐Like Phase Composition in Complex Concentrated Fe32Cu12Ni11Ti16Al29 Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.

The mixed strategy equilibrium of the three-firm location game with discrete location choices [PDF]

open access: yes
In the paper, we derive a symmetric MSE for the three-firm location game on the discrete strategy space. Rather than being uniformly distributed, the MSE for the game has a multimodal distribution.

Reactive Interaction and Wetting of Fe‐ and Mn‐Containing, Secondary AlSi Alloys with Manganese Oxide Ceramic Filter Material for Fe Removal

open access: yesAdvanced Engineering Materials, EarlyView.
Fe‐ and Mn‐containing AlSi alloys undergo aluminothermic reaction with Mn oxide in sessile‐drop and crucible experiments forming poor‐wetting Al2O3 while Mn enriches in the alloy. Primary Fe‐containing particles are preferentially attached to the Mn oxide.
