Plastic deformation of the CaMg C14-Laves phase from 50-250C
Martina Freund, Doreen Andre, Christoffer Zehnder +6
Intermetallic phases can significantly improve the creep resistance of magnesium alloys, extending their use to higher temperatures. However, little is known about the deformation…
Co-deformation Between the Metallic Matrix and Intermetallic Phases in a Creep-Resistant Mg-3.68Al-3.8Ca Alloy
M. Zubair, S. Sandlöbes-Haut, M. Lipińska-Chwałek +5
The microstructure of Mg-Al-Ca alloys consists of a hard intra- and intergranular eutectic Laves phase network embedded in a soft -Mg matrix. For such heterogeneous microstructu…
Deformation of micrometer and mm-sized Fe2.4wt.%Si single- and bi-crystals with a high angle grain boundary at room temperature
Martin Heller, James S. K. -L. Gibson, Risheng Pei +1
Plasticity in body-centred cubic (BCC) metals, including dislocation interactions at grain boundaries, is much less understood than in face-centred cubic (FCC) metals. At low tempe…
Low temperature deformation of MoSi and the effect of Ta, Nb and Al as alloying elements
Carolin Zenk, James S. K. -L. Gibson, Verena Maier-Kiener +3
Molybdenum disilicide (MoSi) is a very promising material for high temperature structural applications due to its high melting point (2030 °C), low density, high thermal conduc…
Investigation of the electroplastic effect using nanoindentation
D. Andre, T. Burlet, F. Koerkemeyer +3
A promising approach to deform metallic-intermetallic composite materials is the application of electric current pulses during the deformation process to achieve a lower yield stre…
On Extracting Mechanical Properties from Nanoindentation at Temperatures up to 1000C
James S. K. -L. Gibson, Sebastian Schröders, Christoffer Zehnder +1
Alloyed MCrAlY bond coats, where M is usually cobalt and/or nickel, are essential parts of modern turbine blades, imparting environmental resistance while mediating thermal expansi…
