Electrical resistivity of microstructural components in Al-Mg-Si alloys
Gautam Kumar, Amram Azulay, Omer Coriat +1
Al-Mg-Si alloys are utilized in large scale electrical conduction applications thanks to their low density, high strength, and low electrical resistivity. The alloying elements, Mg…
Fracture of the 15 CaAl Laves phase at small length-scales
James P. Best, Anwesha Kanjilal, Alireza Ghafarollahi +8
The cubic 15 CaAl Laves phase is a crucial brittle intermetallic precipitate in Mg-Al-Ca alloys. Although knowledge of the mechanical properties of coexisting phases is esse…
Microstructure of a spark-plasma-sintered Fe2VAl-type Heusler alloy for thermoelectric application
Leonie Gomell, Imants Dirba, Hanna Bishara +8
The influence of microstructure on thermoelectricity is increasingly recognized. Approaches for microstructural engineering can hence be exploited to enhance thermoelectric perform…
Universality of grain boundary phases in fcc metals: Case study on high-angle [111] symmetric tilt grain boundaries
Tobias Brink, Lena Langenohl, Hanna Bishara +1
Grain boundaries often exhibit ordered atomic structures. Increasing amounts of evidence have been provided by transmission electron microscopy and atomistic computer simulations t…
Understanding grain boundary electrical resistivity in Cu: the effect of boundary structure
Hanna Bishara, Subin Lee, Tobias Brink +2
Grain boundaries (GBs) in metals usually increase electrical resistivity due to their distinct atomic arrangement compared to the grain interior. While the GB structure has a cruci…
Microstructure manipulation by laser-surface remelting of a full-Heusler compound to enhance thermoelectric properties
Leonie Gomell, Tobias Haeger, Moritz Roscher +5
There is an increasing reckoning that the thermoelectric performance of a material is dependent on its microstructure. However, the microstructure-properties relationship often rem…
Dopant-segregation to grain boundaries controls electrical conductivity of n-type NbCo(Pt)Sn half-Heusler alloy mediating thermoelectric performance
Ting Luo, Federico Serrano-Sánchez, Hanna Bishara +12
Science-driven design of future thermoelectric materials requires a deep understanding of the fundamental relationships between microstructure and transport properties. Grain bound…
Properties and influence of microstructure and crystal defects in FeVAl modified by laser surface remelting
Leonie Gomell, Moritz Roscher, Hanna Bishara +3
Laser surface remelting can be used to manipulate the microstructure of cast material. Here, we present a detailed analysis of the microstructure of FeVAl following laser surfa…
