1. Reactive Sintering of Cu-Al, Ni-Al and Ni-Ti Powder Mixtures
Sammanfattning : Intermetallic compounds are a distinct group of materials having attractive properties and wide applications. In the present work, the formation of intermetallic compounds from elemental components in Cu-Al, Ni-Al and Ni-Ti systems has been studied. Metallic powders were mixed in stoichiometric ratios corresponding to CuAl2, NiAl and NiTi. LÄS MER
2. Oxidation of Fe- and Ni-aluminides in Dry and Humid Atmospheres
Sammanfattning : Aluminides based on Ni3Al and Fe3Al offer good mechanical and corrosion properties at high temperatures and are therefore being considered in the automotive and chemical industries. The aim of this work was to study the early stages and the mechanisms of oxide growth on unalloyed Ni3Al and Fe3Al in air. LÄS MER
