On the influence of ϰ-carbides on the low-cycle fatigue behavior of high-Mn light-weight steels
(2021)
High-manganese light-weight steels offer a great potential for structural purposes in the mobility sector due to their reduced density combined with outstanding mechanical properties. As many of the envisaged applications of these materials will suffer from cyclic loading during their service life, the fundamentals of their fatigue behavior must be studied extensively. In the present work, the low-cycle fatigue (LCF) properties of an austenitic Fe-29.8Mn-7.65Al-1.11C light-weight steel were investigated. Two ...

On the structural integrity of Fe-36Ni Invar alloy processed by selective laser melting
(2020)
Specimens made from pre-alloyed Invar (Fe-36Ni) powder were fabricated by selective laser melting and stress-relief heat treated afterwards. A relative density of the fabricated parts of 99.6 % was determined by computed tomography. The microstructure and mechanical behavior under monotonic and particularly cyclic loading at ambient temperature were investigated. Results reveal a bimodal microstructure containing columnar and equiaxed grains with an average grain size of 75 μm and pronounced texture 〈001〉 || BD. The ...

Investigation of the adhesive strength in a combined compaction and back-injection process to produce back-injected self-reinforced composites (SRCs)
(2022-03-08)
This publication investigates the adhesion between an injection molded component and a self-reinforced composite (SRC) produced in a combined compaction and back-injection process to produce back-injected self-reinforced composites. To study the influence of the process, the parameters barrel temperature, time of injection, and tool temperature were varied. In addition, samples were taken at different positions along the flow path. In light of the orthotropic material behavior of SRCs, investigations were conducted ...

Patterns of Practice - Interdisciplinary Negotiation of Cultural Complexity through Practice-Based Methods in Informatics
(2022)
Following the principle of knowing through making, this thesis discusses development and application of a practice-based methodology for construction of digital artefacts within
cultural contexts. It addresses the epistemological diversity and complexity inhering within interdisciplinary projects, suggesting methodological devices able to navigate the variegated disciplinary landscape present within respective development projects. The conceptual pair complexity/complication acts as theoretical point of reference ...

Ordoliberalism Out of Order? The Fragile Constitutionality of Greek Austerity (Part Two)
(2020-06)
This is the second part of a two-part post. The first part, available here, considered the historical background of the concept of constitutional order and its relation to the ordoliberal project. Judicial independence was examined in parallel with central bank independence, with each understood as a means of insulating policy from social and democratic pressures and also as a means of enacting and maintaining fiscal discipline and market-conforming order. It also included some preliminary observations on the relation ...

Ordoliberalism Out of Order? The Fragile Constitutionality of Greek Austerity (Part One)
(2020-05)
The architecture of the European Monetary Union (EMU) has often been understood to be built on a fundamentally ordoliberal framework. [1] The precise characteristics of what constitutes an ordoliberal framework are often not clarified, and they have been widely debated in contemporary scholarship. But a crucial characteristic of ordoliberalism, and one that has received comparatively little attention, concerns the importance of grounding economic policy in a “constitutional order”: ordoliberal political economy insists ...
