| 摘 要： | This study proposed three types of Al—Hf reactive materials with particle size ratios(a), which were almost completely dense(porosity of <5.40%) owing to their preparation using hot-pressing technology.Microstructure characteristics and phase composition were analyzed, and the influence of particle size ratios on dynamic mechanical behavior and damage mechanism were investigated. The prepared sample with a = 0.1 exhibited continuous wrapping of the Hf phase by the Al phase. Hf—Hf contact(cont...
