| 摘 要： | 超重力熔铸技术是将自蔓延高温合成技术和超重力离心力场耦合的一种新的材料制备技术,但单纯的超重力离心力场不足以使陶瓷产物完全致密,有较大的缩松区域,整体致密度约85%。在超重力熔铸过程中加上一个压力场,可以同步实现陶瓷材料整体致密化,这一技术称为超重力熔铸快速致密化技术,利用该技术制备了整体致密度达98%的YAG陶瓷材料。宏观照片和显微形貌结果显示,所制备的YAG陶瓷材料整体致密,无疏松区,并且晶粒得以细化。

| Abstract: | The technique of combustion synthesis under ultra-high-gravity field which combines the self-propagating high-temperature synthesis and the ultra-high-gravity field is the novel preparation method for the ceramics.But the ceramics can not be dense completely by the gravity field.There are many loosen areas in the YAG ceramics with the relative density 85%.When a weight block places on the system of the combustion synthesis under ultra-high-gravity field,the whole dense production can be prepared quickly.The... |
