    Tetragonal-to-monoclinic phase transformation during thermal cycling and isothermal ageing in yttria-partially stabilized zirconia (1991)

    Notes: Abstract The tetragonal-to-monoclinic (T → M) phase transformation accompanied with thermal cycling has been studied by ionic conductivity, dilatation and X-ray diffraction measurements. With repeating thermal cycling, theM s point shifts to a higher temperature, the amount of expansion due to T → M transformation increases, and the transformation proceeds from the surface in the specimen interiors. These phenomena are attributed to grain boundary cracking which occurs as a result of the transformation. The time-transformation isotherms at 353 K and at room temperature can be expressed by the Johnson-Mehl equationf=1−exp(−bt n ), and the samen value of 0.7 was obtained irrespective of grain size and of environment.

    Discontinuous and continuous coarsening of lamellar precipitates in Cu-Be alloys (1991)

    Notes: Abstract A study has been conducted of the coarsening reaction which occurs after discontinuous precipitation in Cu-Be alloys. When the discontinuous precipitation is nearly complete, a secondary cellular reaction with much coarser interlamellar spacing forms at the original grain boundaries and advances into the primary cells. The growth rate decreases and the interlamellar spacing increases with the cell growth for the secondary reaction. These phenomena are attributed to the continuous coarsening reaction which simultaneously occurs in the primary cells. Theα phase in the cells produced by the first reaction is supersaturated at the initial cell growth, but attains its equilibrium concentration prior to the appearance of the secondary cells. Cold work does not influence the cell growth of the secondary reaction. The driving force for the secondary reaction is the reduction in total interlamellar surface energy.
