Titanium Alloys and Their Characteristics: Part Two
All elements which are within the range 0.85-1.15 of the atomic radius of titanium alloy substitutionally and have a significant solubility in titanium. Elements with an atomic radius less than 0.59 that of Ti occupy interstitial sites and also have substantial solubility (e.g. H, N, O, C). The ease with which solutes dissolve in titanium makes it difficult to design precipitation-hardened alloys.
Titanium Aluminide Alloys: Part One
Titanium aluminide (TiAl) alloys represent a significant advancement in intermetallic materials, offering an exceptional combination of light weight, high strength, and excellent high-temperature properties. These two-phase alloys, primarily based on γ-TiAl with minority α2-Ti3Al phases, exhibit low density (3.85-4.2 g/cm³), high elastic modulus, and good oxidation resistance up to 700°C.
Titanium Aluminide Alloys: Part Two
TiAl alloy is a new alloy based on intermetallic compounds and is characterized by the properties of light weight and high strength. Two-phase TiAl alloys have been receiving considerable attention because of their attractive properties, such as the low density, excellent high-temperature strength, and good oxidation resistance.
Titanium and titanium alloys have rapidly established themselves as essential materials in aerospace, energy, and chemical industries since their commercial introduction in the early 1950s. These materials offer an exceptional combination of high strength-to-weight ratio, superior mechanical properties, and excellent corrosion resistance, making them ideal for critical applications.
