Abstract:Namen tega dela in eksperimentalnih raziskav je ugotavljanje vpliva meje tečenja in temperature preizkušanje na odpornost materiala proti stabilnemu širjenju razpoke (krivulje odpornosti J-R) za konstrukcijsko jeklo in dva mikrolegirana jekla s povišano trdnostjo. Vsi trije materiali so bili preizkušani v treh različnih stanjih: dobavljeno (normalizirano ali poboljšano), deformirano in deformacijsko starano stanje. Preizkusi so bili opravljeni na standardnih preizkušancih CT pri sobni temperaturi in pri temperaturi neduktilnega loma. Za določitev prirastka razpoke med preizkusom je bila uporabljena metoda elastične popustljivosti. Dobljeni rezultati kažejo, da pride pri jeklih z višjo mejo plastičnosti s spremembo stanja materiala in temperature do večjega padca odpornosti materiala proti stabilnemu širjenju razpoke kot pri jeklih z nižjo trdnostjo.

Title:Influence of yield strength and temperature on J-R resistance curves of HSLA steels
Abstract:The aim of this research program was to study the influence of yield strength and temperature on the ductile crack growth resistance (J-R resistance curves) of a common construction steel and three HSLA (high strength low alloy) steels. Three different material conditions were observed: normalized condition (as-delivered), deformed state and aged state. The experiments were carried out on standard CT specimens at room temperature and at the temperature of nonductile tearing. The unloading compliance technique to determine the stable crack growth during the test was used. The results obtained show that HSLA steels with higher yield strength are more sensitive to the condition of the steel and to low temperature influence than lower-strength steels are.
