Lomna žilavost "over-matched" zvarnega spoja, izmerjena na velikih in majhnih preizkušancihRojko, Danilo ; Vuherer, Tomaž ; Gliha, VladimirPri tem delu smo eksperimentalno analizirali posledice trdnostne neenakosti "over-matched" zvarnega spoja in položaja konice na vedenje pri lomu. Zvarni spoj je bil izdelan z varjenjen pod praškom ... (EPP). Primerjali smo lomno žilavost CTOD, določeno pri standardnih upogibnih (SENB) in velikih (WP) preizkušancih ter ocenili vpliv "constraint"-a pri nizkih temperaturah. Pri obeh tipih preizkušancev je bila razpoka narejena z utrujanjem materiala. Konica razpoke je bila v varu in grobozrnatem toplotno vplivanem področju (GZTVP). Lomno žilavost CTOD smo določali na podlagi predpisov, ki jih podaja BS 7448. oz. smernic raziskovalnega centra GKSS.Source: Materiali in tehnologije = Materials and technology. - ISSN 1580-2949 (Letn. 35, št. 1/2, 2001, str. 65-68)Type of material - article, component partPublish date - 2001Language - slovenianCOBISS.SI-ID - 6214166
