Creep behaviors and stress regions of hybrid reinforced high temperature titanium matrix composite
Source abstract
Abstract
Abstract TiB, TiC and La2O3 reinforced titanium matrix composite is in situ synthesized by common casting and hot working technologies. Creep behaviors of the matrix alloy and composite are tested in the temperature range 873–973 K. Steady state creep behaviors of both the matrix alloy and composite are divided into two stress regions. The dominant creep mechanisms are grain boundary sliding and dislocation climbing in the low and high stress regions, respectively. Threshold stresses and stress transfer effects are the two origins of creep resistance enhancement in the composite, which are strongly influenced by the stress regions.
