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 Its Alloys: Selection of Materials and Applications

In selecting titanium and its alloys for any particular application, the engineer must consider both the economic and technological justification for the utilization of this metal in specific components.
Even at the current premium price of titanium, many items for civilian and military uses are justifiable in titanium. In many items the initial high cost of the material is compensated for either by the advantages of weight reduction due to the low density of the metal or by the increased life of the component due to high corrosion resistance of the metal.

Titanium and Titanium Alloys

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.

Titanium Powder Metallurgy Alloys

Titanium powder metallurgy can produce high performance and low cost titanium parts. Compared with those by conventional processes, high performance P/M titanium parts have many advantages: excellent mechanical properties, near-net-shape and low cost, being easy to fabricate complex shape parts, full dense material, no inner defect, fine and uniform microstructure, no texture, no segregation, low internal stress, excellent stability of dimension and being easy to fabricate titanium based composite parts.
