  • Small-punch testing of a weldʹs heat-affected zones = Testiranje lezenja toplotno vplivanih področij vara z uporabo majhnega bata
    Šturm, Roman, 1965- ; Li, Yingzhi
    Small-punch creep tests were performed on four different zones of a P91 welded joint: the base metal (BM), the weld metal (WM), the heat-affected zone on the base-metal side (HAZ-BM) and the ... heat-affected zone on the weld-metal side (HAZ-WM). In addition to the creep-rupture times, full creep-deflection curves were also available, from which the creep properties of different HAZ zones could be derived. In this paper an analytic approach based on Chakrebartyʹs membrane-stretch model and Kachanovʹs creep law is used to interpret the creep-deflection curves of different zones. First of all, the strains and stresses are derived from the observed deflection curves according to Chakrebartyʹs membrane-stretch model, then the Kachanov parameters are determined by attempting to minimize the sum of the squares of the residuals (the difference between the derived stains and the calculated strains at each time point). With the Kachanov parameters known, all the creep properties of the different zones of the welded joint can be obtained.
