1. 1. Intermetallic Compound Formation in Ni-Ti-Fe Powder Mixtures

   Master-uppsats, Lunds universitet/Materialteknik

   Författare :Tea Bertilsson; [2018]
   Nyckelord :Phase Evolution; Ni-Ti-Fe System; Intermetallics; Powder Metallurgy; Reactive Sintering; DSC; SEM; EDS; XRD; Technology and Engineering;

   Sammanfattning : The Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. LÄS MER
