GlidCop trademark DSC properties in the temperature range of 20-350 C

GlidCop trademark AL-25 LOX-80 grade plates manufactured by processes relevant to ITER first wall copper alloy requirements were tested in the temperature range of 20-350 C. Plate manufacturing methods included hot isostatic pressing (HIP), extrusion (EXT), and extrusion followed by cross-rolling (EXT+XROLL). Tests that were performed included tensile, fracture toughness, impact toughness, and creep. The EXT+XROLL plate was found to have higher total elongation, reduction of area, and fracture toughness values than the EXT and HIP plates. All three processes had similar ultimate tensile and 0.2% yield strengths. The HIP material exhibited a lower creep rate than EXT+XROLL. The EXT and the EXT+XROLL plates had similar impact toughness values, which were higher than the HIP plate. Overall, the EXT+XROLL plate had the best combination of properties of the three processes examined. (orig.)
