Abstract:Na simulatorju Gleeble smo pripravili vzorce materiala z mikrostrukturo štirih različnih TVP ob črti taljenja. Iz njih smo izdelali preizkušance za merjenje udarne in lomne žilavosti. Lomno žilavost smo izmerili pri dveh vrstah majhnih preizkušancev z razpoko: pri okroglih nateznih in upogibnih SENB-preizkušancih. Pri prvih smo lahko določili ▫$K_{Ic}$▫, pri drugih pa ▫$theta_{c}$▫. Ko primerjamo vrednosti ▫$theta_{c}$▫ s ▫$K_{Ic}$▫, dobimo preoptimistične rezultate. Debelina SENB-preizkušancev je tudi pri zelo nizki lommni žilavosti še premajhna.

Title:Comparison of HAZ fracture toughness measured by two types of small scale specimens
Abstract:Samples of material with microstructures of four different HAZ situated at the fusion line were prepared on a Gleeble simulator. Specimens for the experimental determination of impact and fracture toughness were machined from samples. The fracture toughness was measured on two types of small pre-cracked specimens. The ▫$K_{Ic}$▫ was determined on round tensile specimens while the ▫$theta_{c}$▫ was obtained from SENB specimens. The results obtained from the SENB specimens are too optimistic in comparison with the ▫$K_{Ic}$▫. The SENB specimens are not thick enough, even at very low fracture toughness.
Keywords:weld joint, constructional steel, heat-affected zone (HAZ), fusion line, thermal influence, fracture toughness
