The Mechanical Behaviour of Ultra Fine Grained Titanium Alloys at High Strain Rates

nm were obtained. The mechanical behaviour was studied over a wide range of strain rates from 10^(-3) - 107 s^(-1) under compressive loading using different experimental techniques. A significant increase [...] strain rate sensitivity of the material is found to be constant within a range of strain rates from 10^(-3) to 106 s^(-1) but increases at higher plastic strains. However, compressive deformability is nearly …

A Study on the Critical Thickness of the Inner Tube for Magnetic Pulse Welding Using FEM and BEM

welding dissimilar metals, Magnetic Pulse Welding (MPW) has attracted much attention. In this study, 3A21 aluminium alloy used as outer tube was welded to 20Fe tube by MPW. In order to investigate the critical [...] thickness of the inner tube (20Fe) which is subjected to huge impact pressure from the outer tube (3A21), both numerical simulations and experiments were carried out. For the purpose of investigating the …

Control of Velocity, Driving Pressure, and Planarity During Flyer Launch with Vaporizing Foil Actuat

0.508 mm thick AA2024-T3 sheets toward a photonic Doppler velocimeter (PDV) probe. Launch velocities ranging between 300 and 1000 m/s were observed over a distance of less than 3 mm, and repeated trials …
