Modeling of the constitutive behavior was undertaken for Fe- Cr-C tempered martensitic alloys. Tensile tests were carried out at room temperature and constant nominal strain rate. In order to obtain a fully martensitic structure with different prior austen ...
In this study, the tensile and fracture properties and the microstructure of the reduced-activation tempered martensitic steel Eurofer97 have been investigated. This technical alloy is a 9%Cr steel developed within the European fusion material research pro ...
The feasibility of using a low temperature liquid composite molding technique to produce smart composites with embedded shape memory alloys was investigated. The epoxy system of EPON 828 resin and DETA hardener was evaluated, with embedded NiTiCu shape mem ...
Toughness measurements of a Ti-45Al-2N4u-2Nb + 0.8%vol TiB2 alloy with a. near fully lamellar microstructure and a Ti-46Al-8Nb alloy with a convoluted microstructure are performed at 650 degrees C under vacuum according to ASTM Standard E1820. Respective v ...
X-ray absorption near-edge structure (XANES) spectroscopy is applied to Zr-based alloys ((Zr, x%Nb) with x ⩽ 1 wt.%) corroded in steam at 415 °C to resolve the niobium speciation in the metal and the oxide parts of their metal/oxide interface. By combining ...
Mechanisms responsible for the embrittlement of leaded "free-machining" copper alloys at intermediate temperatures (i.e. around 400 °C) are examined using a combination of microstructural and mechanical characterization. Tensile tests are conducted on pure ...
Ductile fracture in steels is essentially due to cavity nucleation, growth and coalescence. Once voids are initiated in the metallic matrix, and the deformation continues to increase, voids grow in size and finally coalescence to fracture. This dissertatio ...
Materials design limits derived so far from the data generated in Europe for the reduced activation ferritic/martensitic (RAFM) steel type Eurofer are presented. These data address the short-term needs of the ITER Test Blanket Modules and a DEMOnstration f ...
The mechanical properties of high volume fraction SiC-particle reinforced Al-based metal matrix composites (MMCs) produced by means of pressurized liquid metal infiltration (squeeze casting) are shown to be triggered by matrix alloying and heat treatment p ...
A fracture toughness database obtained on the Eurofer97 steel (25 mm plate, heat 83697) is presented. The material has been tested in the 'as-received' condition in the lower transition region at temperatures ranging from 173 K down to 123 K. Sub-sized (0. ...
