Abstract:
The research advances in high density tungsten alloy strengthening techniques of alloying, rotaryswage, torsional deformation and hydrostatic extrusion are reviewed. The research status of the adiabatic shear mechanism and numerical simulation is also introduced. The latest research progress in special manufacturing techniques, including mechanical alloying for nanometer tungsten alloy composite powder, warm compaction and preoxided activation sintering, is introduced. Based on the analysis of some main problems existing in the development of high density tungsten alloy for armour-piercing projectile, the future research directions, tactics and measures are put forward.[著者文摘]
