Polycrystalline specimens of the ferritic-martensitic OPTIMAX A steel have been irradiated on the one hand with neutrons at 523 K to a dose of 2.5 dpa and with 590 MeV protons at ambient temperature and 523 K to doses of about 0.3 and 1 dpa on the other. C ...
The ball punch test technique was used to evaluate the conventional tensile and impact properties of the tempered martensitic steel EUROFER97 from room temperature down to liquid nitrogen temperature. The testing was carried out on unirradiated material on ...
The microstructure and tensile behavior of pure single crystalline Ni irradiated with 590 MeV protons are investigated. First results have been obtained for a damage level of 0.13 dpa at room temperature and 0.002 dpa at 523 K. The irradiation induced defe ...
A series of polyquasicrystalline ingots with the nominal composition Al63.6Cu24.0Fe12.4 has been prepared by conventional drop casting and subsequent annealing at 1088 K for 24 h. Compression specimens prepared from the different ingots have been deformed ...
AISI 304 and 316 stainless steels of two purity levels that have been irradiated with high energy protons up to 0.3 dpa and neutrons in a high flux reactor up to 7.5 dpa were investigated in terms of irradiation induced mechanical properties and microstruc ...
The microstructure of commercially available nanocrystalline (nc) electroplated Ni foils is studied by means of Xray diffraction and transmission electron microscopy. It is shown that the microstructure is inhomogeneous and batch-dependent. Tensile propert ...
There is an increasing interest by the flavor industry for producing natural aroma compds. through biocatalysts. L-Phenylalanine is transformed by Saccharomyces cerevisiae into 2-phenylethanol, which has a rose-like odor. Unfortunately this product inhibit ...
We have studied systems of asymmetric coupled GaAs V-groove quantum wires, in which the electrons and holes are injected into different wires. Our experimental results indicate efficient electron and hole tunneling, despite a 7 nm thick AlGaAs tunnel barri ...
The differences and similarities of behaviour between fee and bcc metals after irradiation have been investigated. For this purpose, fee Cu, Pd and 304 stainless steel and bcc Fe, Mo and Mo-5% Re were irradiated with either neutrons or 590 MeV protons at t ...
Liquid metal embrittlement (LME) is illustrated on the Cu-Bi and Cu-PbBi systems at 300 C using either constant strain-rate tests at 10(-4) s(-1) or constant load tests at 25% of yield stress. Intergranular penetration was studied in the Ni-Bi system at 70 ...
