EXPLORING DAMAGING MECHANISMS AND THEIR LINK TO CASTING PROCESS OF HEAVY-WALLED DCI BY MEANS OF CT

摘要

trepanned samples are collected from heavy-walled DCI components during production. These are then HCF tested, partly after CT-scanning. Fracture surface is then physically detected and compared to CT data. By crossing the info from CT, fatigue failures and process parameters new insights on the damaging mechanisms and their link to production parameters are derived.
