摘要: Abstract The reactive spontaneous infiltration of Al-activated TiO2 (anatase) was investigated. Pure Al powder blended with for activation. They were compacted into the preform and then sealed within 6060 alloy mould. activation carried out in bath 1 h comparative sintering experiments an argon protected environment under same conditions temperature duration. X-ray diffraction analysis proved that superior to protection on activating reaction between TiO2. blending ratio found play most important role by affecting kinetics. Three main types microstructures observed after infiltration: full infiltration, partial formation cracks no infiltration. these explained basis kinetics local volume changes due reactions. Ultimately, it is obtain overall good a around 3:7 900 °C are suitable.
