Effect of plasma hardfacing and carbides presence on the occurrence of cracks and microcracks
(Society for Structural Integrity and Life, Institute for Material Testing, 2018)
Presented is the effect of plasma hardfacing (or just hardfacing) and carbides presence on the occurrence of cracks and microcracks in the welded layer. The reasons behind this phenomenon are analysed and explained. In ...
Microstructure evolution and mechanical properties degradation of HPNB alloy after an eleven-year service / Mikrostrukturni razvoj i degradacija mehaničkih svojstava legure HPNB posle jedanaest godina eksploatacije
(Society for Structural Integrity and Life (DIVK), 2022)
In this work, the heat-resistant cast steel HP40Nb alloy, produced in the form of a centrifugally cast tube, which failed after 11.4 years service is investigated. The microstructure is examined using a scanning electron ...
