V R. Palkar, D Thapa, M S. Multani, S G. Malghan

We have shown that it is possible to achieve dense nanostructured alumina, with density + 98% of the theoretical maximum at sintering temperature as low as 1300 C without any help of additives of Α-seeding. The drastic reduction in sintering temperature

H Ahn, Gerald V. Blessing, John A. Slotwinski, S Jahanmir

A pulse-echo ultrasonic technique consisting of focused normal-incident compressional waves was used for the detection and evaluation of surface and subsurface damage in micaceous glass-ceramic and silicon nitride samples. The damage was produced by
