Abstract
By inducing thermal explosion in high-gravity field to prepare the laminated composite of TiB2-based ceramic and Ti-6Al-4V alloy, spatial span-scale continuously-graded microstructure was achieved in interfacial region between the ceramic and Ti alloy, and the formation of the interfacial microstructure resulted from full-liquid ceramic-metal fusion, atomic interdiffusion and subsequent peritectic reaction of TiB2 primary phases with Ti liquid of graded concentration. By using 14.5 mm AP to conduct DOP test to evaluate ballistic performance of the laminated composite, it was considered that comparing to TiB2-based ceramic, the presence of spatial span-scale continuously-graded microstructure between the ceramic and Ti alloy brought about the enhanced ballistic performance of the laminated composite by 133.0%.
