Description
Some characteristics of fracture in creep of five Zr-Sn-Mo alloys and a Zr-Sn-Mo-Nb alloy at temperatures between 673 and 823 K, and in a broad applied stress interval are summarized and discussed. Applied stress and temperature dependences of time to fracture were obtained, as well as relations between creep strain to fracture and time to fracture, and relations between creep strain to fracture and applied stress. Further, relations between 'mean' creep rate, defined as the ratio of creep strain to fracture and time to fracture, and steady state creep were determined. The results are discussed considering temperature and applied stress dependences of steady state creep rate. It is suggested that fracture in creep is controlled by the same mechanism as the creep itself. The influence of alloy composition on time to fracture was evaluated and the strengthening effect of tin, molybdenum and niobium is discussed. (Auth.)
