9409456 Nettleship This Research Initiation Proposal is to support an experimental study of concurrent creep and densification of ceramic materials. Two existing theoretical models will be evaluated by a systematic experimental study and comparison made by data obtained during pressureless sintering and a sinter-forging operation. Compacts of alumina powder will be prepared by colloidal methods and sintered in a specially designed constant load creep apparatus. Finally, the sensitivity of the adapted models to processing variables such as particle size and shape will be examined. ***

本研究启动提案旨在支持一项陶瓷材料同步蠕变和致密化的实验研究。两种现有的理论模型将通过系统的实验研究和无压烧结和烧结-锻造操作数据的比较来进行评估。氧化铝粉末将通过胶体方法制备，并在专门设计的恒载蠕变装置中烧结。最后，适应模型的敏感性处理变量，如颗粒大小和形状将被检查。＊＊＊
