Ti-6Al-4V (UNS designation R56400), also sometimes called TC4, Ti64, [1] or ASTM Grade 5, is an alpha-beta titanium alloy with a high specific strength and excellent corrosion resistance.
Titanium has outstanding corrosion resistance to seawater, and thus is used in propeller shafts, rigging and other parts of boats that are exposed to seawater. Titanium and its alloys are used in airplanes, missiles, and rockets where strength, low weight, and resistance to high temperatures are important.
Ductile. Corrosion-resistant. For brazing titanium to titanium and titanium to stainless steel. 82: 9: Ga 9: Cu 62 Au 35 Ni 3: Au–Cu 974/1029 [54] [75] – BAu-3, Premabraze 127, Nicoro. For nickel, kovar, stainless steel, molybdenum, and molybdenum-manganese metallized ceramics. Excellent wetting, low base metal erosion. 62: 35: 3: Au 35 Cu ...
Titanium's durability, light weight, and dent and corrosion resistance make it useful for watch cases. [115] Some artists work with titanium to produce sculptures, decorative objects and furniture. [123] Titanium may be anodized to vary the thickness of the surface oxide layer, causing optical interference fringes and a variety of bright colors ...
The unshaded bars indicate the location on the chart of those steels when in acidic/stagnant water ( like in the bilge ), where crevice-corrosion happens. Notice how the *same* steel has much different galvanic-series location, depending on the electrolyte it's in, making prevention of corrosion .. more difficult.
Titanium aluminide (chemical formula TiAl), commonly gamma titanium, is an intermetallic chemical compound. It is lightweight and resistant to oxidation [1] and heat, but has low ductility. The density of γ-TiAl is about 4.0 g/cm 3. It finds use in several applications including aircraft, jet engines, sporting equipment and automobiles.
Increases the toughness of steel, thus making molybdenum a very valuable alloy metal for making the cutting parts of machine tools and also the turbine blades of turbojet engines. Also used in rocket motors. Nickel: 2–5 Toughener 12–20 Increases corrosion resistance Niobium — Stabilizes microstructure Silicon: 0.2–0.7 Increases strength 2.0
Stainless steel alloys remain a research target because of lower production costs, as well as the need for an austenitic stainless steel with high-temperature corrosion resistance in environments with water vapor. Research focuses on increasing high-temperature tensile strength, toughness, and creep resistance to compete with Ni-based superalloys.
