Phase Field Modelling Of Twinned Dendrite Growth

Michel Rappaz, Jean-Luc Desbiolles, Mario Alberto Salgado Ordorica

Twinned dendrite growth has been found to occur in aluminum alloys when critical thermal conditions (G approximate to 100 K/cm, nu(s) approximate to 1 mm/s) and a slight convection in the melt are present during directional solidification. Split in their t ...

Quench propagation in coated conductors for fault current limiters

Frédéric Sirois, François Roy, Bertrand Dutoit

A fundamental understanding of the quench phenomenon is crucial in the future design and operation of high temperature superconductors based fault current limiters. The key parameter that quantifies the quenching process in superconductors is the normal zo ...

Numerical studies of the quench propagation in coated conductors for Fault Current Limiters

Frédéric Sirois, François Roy, Bertrand Dutoit

A fundamental understanding of the quench phenomenon is crucial in the future design and operation of HTS based Fault Current Limiters (FCLs). The key parameter that quantifies the quenching process in superconductors is the normal zone propagation (NZP) v ...

The strength of annealed, heat-strengthened and fully tempered float glass

Pieter Christian Louter

In the last two decades architectural glass has made an enormous leap from a secondary material to a material that combines structural and cladding roles. The structural role is a new and problematic one. In contrast to most other engineering materials the ...

3D finite element and experimental study of the size requirements for measuring toughness on tempered martensitic steels

Philippe Spätig, Pablo Federico Mueller

The fracture properties of the tempered martensitic steel Eurofer97, which is among the main candidates for fusion power plant structural applications, were studied with two sizes of pre-cracked compact specimens (0.35T C(T) and 0.87T C(T)). The fracture t ...

Mechanical spectroscopy of 18-carat AuCuPd white gold alloys

Daniele Mari, Robert Schaller, Iva Tkalcec Vâju, John Hennig

The mechanical loss and dynamic modulus temperature spectra of two 18-carat white gold alloys, Au58%Cu24%Pd18% without (grade A) and with alloying additions (grade B), were measured in the 400-1000 K temperature range. A peak interpreted as a Zener relaxat ...

Fracture toughness master-curve analysis of the tempered martensitic steel Eurofer97

Philippe Spätig, Raul Alejandro Bonadé, Pablo Federico Mueller

We report fracture toughness data for the reduced activation tempered martensitic steel Eurofer97 in the lower to middle transition region. The fracture toughness was measured from tests carried out on 0.35T and 0.87T pre-cracked compact tension specimens. ...

Tempering effects on three martensitic carbon steels studied by mechanical spectroscopy

Daniele Mari, Robert Schaller

Tempering effects have been studied in three martensitic carbon steels by mechanical spectroscopy. The mechanical-loss spectra present a relaxation peak similar to the Snoek-Koster peak in ferrite. The peak amplitude decreases upon tempering, indicating a ...

On the relationship between the microstructure and the mechanical properties of an ODS ferritic/martensitic steel

Amuthan Ramar

In the quest of materials for the first wall of the future fusion reactor, it has been shown that oxide dispersion strengthened (ODS) ferritic / martensitic (F/M) steels appear to be promising candidates. The inherent good mechanical properties supported b ...

Microstructure of precipitates and magnetic domain structure in an annealed Co38Ni33Al29 shape memory alloy

Barbora Bártová

The microstructure of a Co38Ni33Al29 ferromagnetic shape memory alloy was determined by conventional transmission electron microscopy (TEM), electron diffraction studies together with advanced microscopy techniques and in situ Lorentz microscopy. Rod-like ...
