Chemical Composition:Table 1 outlines the chemical composition of the Ti-6Al-4V alloy. The primary elements include
Titanium (Ti) as the balance, Aluminum (Al) ranging from 5.5% to 6.5%, and Vanadium (V) from 3.5% to 4.5%. Other elements such as Iron (Fe), Carbon (C), Nitrogen (N), Hydrogen (H), Oxygen (O), Yttrium (Y), and Silicon (Si) are present in smaller quantities, with specific maximum limits for each.
Mechanical Properties:
Table 2 presents the mechanical properties of Ti-6Al-4V based on diameter and direction. For diameters ≤50.8 mm, the tensile strength (σb) is ≥931 MPa, and yield strength (σ0.2) is ≥862 MPa, with elongation (A) and reduction of area (Z) both ≥10% and ≥25% respectively. For larger diameters, the values slightly decrease but maintain high performance standards.
Applications and Characteristics:
Ti-6Al-4V is a typical α+β titanium alloy known for its medium to high strength, excellent fracture toughness, fatigue performance, and good processing capabilities. It is widely used in the aerospace industry for aircraft structures, engine blades, and fasteners. WST offers a range of Ti-6Al-4V products in various forms and sizes, from billets to wires, adhering to industry specifications.
