| Abstract: | In this paper, the main preparation processes and heat-treatment methods for tungsten alloy, especially, W-Ni-Fe, are introduced. Some important progresses in recent decades, related to tungsten alloy under high velocity impacting, the dynamic mechanical properties, the constitutive law, the shearing band etc., are reviewed from angles of experimental technology and observations, theoretical models, microstructural analyses. Some promising research fields on the tungsten alloy and its applications on the ordnance are pinpointed. |
