Present activities • Collect existing data, prepare TDR
Present activities • Collect existing data, prepare TDR Severe cracking of the tungsten due to the thermal gradients. Nelson et al. IWSMT-10, JNM, in press.
Present activities • Start experiments on reference tungsten and W-alloys Tungsten alloy: IT180 in helium with 5% oxygen for 2.5 hours. S. Iyengar, E. Malm, Lund Technical University
Short term (2012-13) plan • Investigations on reference tungsten material Characterization of as-received materials Density, Metallurgy, Hardness Mechanical testing at ESS relevant temperatures Tensile, Fatigue, Bend Microstructural analyses TEM: as-received, after testing SEM: fracture behaviour Erosion experiments at KIT( tbd) Oxidation experiments at LTU (tbd)
Short term (2012-13) plan • Investigations on irradiated tungsten material Mechanical testing and Microstructural analyses of STIP-II (@JAEA) and STIP-V (@PSI) samples Tensile, Hardness, Metallurgy, TEM, SEM, gamma-measurements etc.
Overview of materials irradiated in STIP PIE has been partially done.
