Nickel titanium phase diagram. PDF Aluminium - Nickel - Titanium - MSIport phase diagram is given in [88Mur]. The binary system Ni-Al is essentially based on [Mas2], however, according to [87Hil, 88Bre, 91Ver], the γ' phase (Ni 3 Al) in the Ni-Al system is formed by a reaction L + γ(Ni)ºγ' at 1372°C and the binary eutectic γ'(Ni 3 Al) + β 1 (NiAl) solidifies at 1369°C. The Ti-Ni binary phase diagram is taken from [Mas2]. en.wikipedia.org › wiki › Alloy_steelAlloy steel - Wikipedia Manganese, silicon, nickel, and copper are added to increase strength by forming solid solutions in ferrite. Chromium, vanadium, molybdenum, and tungsten increase strength by forming second-phase carbides. Nickel and copper improve corrosion resistance in small quantities. Molybdenum helps to resist embrittlement. › applications › marineCopper-Nickel Alloys: Properties, Processing, Applications 1.3 Effect of alloying elements. Nickel has a significant effect on the physical and mechanical properties of Cu-Ni alloys (see 2.). While tensile strength, 0.2% proof strength, hot strength, solidus and liquidus temperature and corrosion resistance increase with nickel content, thermal and electrical conductivity decrease. en.wikipedia.org › wiki › A15_phasesA15 phases - Wikipedia The A15 phases (also known as β-W or Cr 3 Si structure types) are series of intermetallic compounds with the chemical formula A 3 B (where A is a transition metal and B can be any element) and a specific structure.
