The Ternary System Nickel/Silicon/Titanium Revisited [PDF]
Zeitschrift für anorganische und allgemeine Chemie, 2010 AbstractThe constitution of the ternary system Ni/Si/Ti is investigated over the entire composition range using X‐ray diffraction (XRD), energy dispersive X‐ray spectroscopy (EDS), differential thermal analysis (DTA), and metallography. The solid state phase equilibria are determined for 900 °C. Eight ternary phases are found to be stable.
