Combustion Wave Propagation during SHS of Bi-Layered System (Ti-2B-60wt%Cu)/(3Ti-2BN-x)
摘要
Abstract
The effects of Cu content and density of powder compacts on the features and velocity of the combustion wave during its propagation through the bi-layered powder compacts of (Ti-2B-60wt%Cu)/(3Ti-2BN-xCu) (x=0, 10, 20, 40wt%) were investigated. The combustion wave velocity for specimen (3Ti-2BN), (3Ti-2BN-10wt%Cu), (3Ti-2BN-20wt%Cu) and (Ti-2B-60wt%Cu) compacted with pressure p=60MPa is 4.96, 4.43, 2.17 and 18.52mm/s respectively. While, combustion wave cannot propagate through the specimen of (3Ti-2BN-40wt%Cu). In (Ti-2B-60wt%Cu)/(3Ti-2BN-x) bi-layered system, the features of the combustion wave change from bending toward the (3Ti-2BN-x) layer to cutting as wedge-shape to this layer as the x increased. Besides, the effects of green densities of specimens compacted with p=12, 24, 84, 108MPa on the feature and combustion wave velocity were investigated关键词
