Participation in ICSID 2019, Dubrovnik, 4 – 7 June 2019


The paper with the title “Fracture and Failure Analysis of a Nickel Aluminium Bronze (NAB) Chain Connector of a Drawing Machine” authored by Dr. A. Vazdirvanidis and Dr. G. Pantazopoulos from ELKEME S.A. was presented in the poster session of the 3rd International Conference on Structural Integrity and Durability (ICSID 2019), 4-7 June 2019, Dubrovnik Croatia. The paper presents the investigation results of the failure analysis of a Ni-Al bronze component from a chain assembly, using fractographic and metallographic analysis, through optical and scanning electron microscopy. The investigation findings suggested fatigue failure initiated at the area of fillet due to poor machining conditions, forming stress raiser and crack propagation facilitated by the presence of interdendritic κ-phases.  Dr. George Pantazopoulos was also served as chairman of the session “Fatigue and fracture of weldments, welded components, joints and adhesives” which was held on 6th June 2019.
