Quality Enhancement of Laser Powder‐Bed Fusion Parts by Acoustically Assisted Additive Manufacturing by Laser Powder‐Bed Fusion and its Application to Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

From Top To Bottom (and Back To The Top Again): Federal Spending, Sub-national Coalitions, and Protests in Argentina, 2002–2006 De arriba abajo (y vuelta arriba otra vez). Gasto federal, coaliciones subnacionales y protesta en Argentina, 2002-2006

open access: yesJournal of Politics in Latin America, 2012
Can federal-state relations affect popular protests? Using an extensive dataset measuring local protests in the Argentine provinces (2002–2006), I assess the effects of the president’s and governors’ tactical allocations on the persistence of contentious

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

open access: yesAdvanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...

Mitigation of Cracks in High‐Performance Nickel‐Based Superalloys in Powder Bed Fusion Laser Beam of Metals Using a Metal Matrix Composite Approach

open access: yesAdvanced Engineering Materials, EarlyView.
High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

The Politics of Reform: Political Scandals, Elite Resistance, and Presidential Leadership in Indonesia

open access: yesJournal of Current Southeast Asian Affairs, 2010
While Indonesia’s democracy has received much acclaim for institutionalizing fair, free, and peaceful elections, many important challenges still lie ahead. The "politics of reform," which has consumed much of the government’s time and energy, are a mixed

On the Deformation Behavior of Metastable CrMnNi Steels Processed by Directed Energy Deposition in Different Temperature Regimes

open access: yesAdvanced Engineering Materials, EarlyView.
In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for
