The amount of chromium and molybdenum present in the alloy has a significant effect on the corrosion properties of the metal. This study examines the influence of chromium and molybdenum on four nickel-based alloys (Table 1), including Alloy 22 (UNS N),(1) in various salt by: This paper describes the structure and properties of an innovative Fe-Al-Si alloy with a reduced amount of silicon (5 wt. %) in order to avoid excessive brittleness. The alloy was produced by a combination of mechanical alloying and spark plasma sintering. Nickel and titanium were independently tested as the alloying elements for this alloy. It was found that wear resistance, Author: Pavel Novák, Zdeněk Barták, Kateřina Nová, Filip Průša.
