Fractographic Study

The residual stress left on the fracture surface is one of the important parameters in X-ray fractographic study. It has been used to analyze fracture mechanisms in fracture toughness and fatigue tests especially of high strength steels.In this paper, X-ray fractography was applied to brittle fracture of alumina (Al2O3) and zirconia (ZΓO2) ceramics.

Abstract New materials in the Al-Zn-Mg-Cu-La alloy system have been proposed for improving corrosion resistance in a study by Kishi et al, because Lanthanum, La, has a storage capability for hydrogen. Hydrogen is a problem in the stress corrosion cracking (SCC) growth mechanism. Zinc, Zn, Magnesium, Mg, and Copper, Cu, in the alloy have influenced the extrusion, strength and other properties; however, in the case of putting this material to use, it is also necessary to evaluate it from the viewpoint of fracture mechanics. The stress intensity factor, K, obtained from fracture mechanics is a necessary parameter for the evaluation of various materials. The first part of this study deals with the measurement of fatigue crack growth in the Al-Zn-Mg-Cu-La alloy system. The second part evaluates the fracture surface obtained from tests of these materials by the application of x-ray fractography.

Citrate Process

Ceramics based on Y-doped BaCeO3 were prepared by citrate process. The X-ray fluorescence shows that barium stoichiometry deviation is established during calcination step. Through the SEM analysis of fracture surface of sintered samples it was possible to infer that powder highly deficient of barium shows higher diffusion coefficient during sintering than stoichiometric powder promoting grain growth and, consequently, trapping pores into the grains.
