Thermal Activation, Intermittency and Size Effects in the Plastic Deformation of Cast Aluminium Microwires

Suzanne Godelieve Alphonsine Verheyden

The microcasting process is a scaled-down investment casting process in which molten metal is pressure-infiltrated and directionally solidified in water-soluble moulds. It was previously developed to produce metallic microwires with a diameter (D) between ...

Creep and stress relaxation of a FeMnSi-based shape memory alloy at low temperatures

Cyril Cayron, Christian Leinenbach

The creep and stress relaxation behavior of a Fe-17Mn-5Si-10Cr-4Ni-1(V,C) (wt%) shape memory alloy at low homologous temperatures (-45 degrees C < T < 50 degrees C) was systematically studied in stress and strain controlled tensile tests. At constant stres ...

Embrittlement induced by the synergistic effects of radiation damage and helium in structural steels

Kun Wang

Ferritic/martensitic steels are candidate materials for fusion reactor structural components, liquid metal containers of spallation neutron sources, and accelerator driven systems, with good radiation resistance and thermo-mechanical properties. However, e ...

On the origin of cementite diffraction peak broadening during tensile deformation at ambient temperatures

Helena Van Swygenhoven, Steven Van Petegem, Michael Andreas Weisser

We report on the diffraction peak shape evolution from cementite particles in three steel microstructures, recorded during in-situ tensile deformation at room temperature. We demonstrate that in a bainitic tempered steel the observed peak broadening and as ...

Correlation between ferrite grain size, microstructure and tensile properties of 0.17wt% carbon steel with traces of microalloying elements

Shankha Nag

Five different grain sizes are produced in 0.17 wt% carbon steel using varying rates of cooling from austenitization temperatures. Controlled furnace cooling from 1100 °C and 950 °C produces coarse ferrite grains of 40 µm and 32 µm diameter, respectively, ...
