The organisation of COST Actions is described together with the close-knit, integrated type of research that is conducted in the materials programmes by collaborators representing industry, research institutes and universities. In COST 501, on advanced materials for power engineering components, ultrasonic and other forms of NDE are applied, for example to gas turbine blades, steam turbine castings and forgings. This type of research is illustrated by a description of the work of the coordinated group which is evaluating computer-aided methods for ultrasonic examination and assessment of naturally occurring defects in forgings weighing up to 60 t. The effect of stress cycles imposed on large samples containing identified single or cloud type defects during a simulated lifetime is determined before fracturing them to enable the actual defect size to be measured.
