Effect of warm pre-stressing on fracture toughness of Eurofer97 steel

Philippe Spätig, Nazar Ilchuk

Experiments and finite element simulations have been carried out to assess the warm pre-stressing effects on the effective fracture toughness of the high-chromium reduced activation tempered martensitic steel Eurofer97. The experiments have been conducted ...

Processing and Consolidation of TaC/HfC Based Composites Using MoSi2 and Carbon Nanotubes

Mehdi Mazaheri

Tantalum and hafnium carbides are classified as Ultra High Temperature Ceramics (UHTC) because of their extreme melting temperatures (above 3900 degrees C). Therefore, these materials can safely operate in the range of temperature that any other materials ...

Fracture of convoluted and lamellar α2 + γ TiAl alloys

Andreas Mortensen, Frédéric Diologent

Fracture toughness tests are conducted at room temperature and 923 K (650 degrees C) on SENB (Single Edge Notched Bend) specimens of three different (alpha(2) + gamma ) TiAl-based alloys. One alloy is a conventional near fully lamellar Ti-45Al-2Mn-2Nb + 0. ...

The effect of processing conditions on the microstructure and impact behavior of melt infiltrated Al/SiCp composites

Mehdi Mazaheri

In the current research, pressureless melt infiltration (PM!) was applied to study the effect of different processing conditions on the final properties of Al/SiC composites, fabricated through the infiltration of aluminum melt into SiC particulates porous ...
