Ductile B2 Intermetallics‐Driven Strength‐Ductility Synergy in Heterolaminated Multi‐Principal Element Alloys

open access: yesAdvanced Science, EarlyView.
Intrinsic phase toughening transforms a brittle B2 intermetallic into a plastically deformable, load‐bearing phase, while a heterogeneous laminated architecture suppresses strain localization and interface cracking. The synergy between ductile intermetallics and mesoscale heterogeneity establishes a general design strategy for breaking the long ...

City age and city size [PDF]

open access: possibleEuropean Economic Review, 2014
Abstract Using novel data on the foundation dates of more than 10,000 American Census places, we show that older cities in the US tend to be larger than younger ones. To take this nexus between city age and city size into account, we introduce endogenous city creation into a dynamic economic model of an urban system.

On the number and size of cities*

Journal of Economic Geography, 2005
We study the effects of a decrease in inter-city transport costs on the spatial distribution of population in a multi-regional economy, when a rise in the regional population generates higher urban costs. Holding the number of cities constant, as transport costs are reduced gradually from a very high level to a very low level, there is a first phase in
