    Transmission electron microscopy investigation of an ordered metastable phase in Zr-N alloys
    with S. Sharma and K. Moore
    Philosophical Magazine 83 (1): 31-51. 2003.
    Supersaturated hcp f -Zr alloys containing 22-28 at.% N were prepared by nitriding sheets of Zr in an atmosphere of high-purity N 2 , followed by homogenization under high-purity Ar gas. Quenching and isothermal ageing of the alloys for various times between 500 and 650°C resulted in precipitation of a metastable phase, rather than the equilibrium phase ZrN. This investigation focused on determining the structure, orientation relationship, habit plane, morphology, growth kinetics and atomic grow…Read more

    The eleven essays in this volume offer diverse approaches to very different landscapes. Yet they agree in viewing medieval western European landscape as artifact, as territiry constructed by medieval people on several interrelated levels. By helping to articulate how places came to be managed, created, and imagined, they offer their readers a much better apprecitaion of what might be called a "deep ecology" of the Middle Ages. --introd.
