Research ArticleOpen accessIn the abstractCreep-Fatigue Crack Growth Interaction in Nickel Base Supper AlloyF. DjavanroodiMost engineering components which operate at elevated temperatures are subjected to non-steady loading during service. This paper describes the current fracture mechanics concepts that are employed to predict cracking of Nickel base supper alloy materials at high temperatures under low and high frequency cyclic loading. A model for predicting creep crack growth in terms of C* and the creep uniaxial … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Heat Treatment Parameters on Distribution and Volume Fraction of Mg2Si in the Structural Al 6063 AlloyG. Al-MarahlehAluminum Profiles -Production by extrusion from aluminum billets require a certain degree of homogeneity because of the segregated second phase particles, which are available in the as cast structure of the billets. Worldwide practice suggests a long homogenizing process at elevated temperatures in order to achieve such condition. This study showed that profiles extruded from homogenized and unhomogenized billets did … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 8 May 2006 · 7,783 accessesView PDFCite
