摘要：
Ultra-fine grained tungsten specimens with a grain size from the submicron range to several microns were fabricated by resistance sintering under ultra-high pressure. Transient heat loads were applied on the tungsten specimens at room temperature for a pulsed duration of 5 ms at different power density of 0.22, 0.33. 0.44 and 0.55 GW m(-2), respectively, by using an electron beam facility. The crack formations and surface melting behaviors under transient heat load were investigated. (C) 2009 Elsevier B.V. All rights reserved.
