Abstract:

Marked loss in strength of sintered material appeared at 3720 F. The density spread on sintered samples was reduced from 0.40 to 0.11 gcc. with densiies averaging about 4.90 gcc. Laboratory studies on sintering procedures have been curtailed as being nearly completed. Tests on sintered samples are well advanced. Hot pressing studies have been resumed to provide experimental daa equal in scope to that developed for sintered ware. Hot pressed densities of 5.50 gcc. seem practical. Strengths of over 36,000 psi at room temperature have been measured on hot pressed sample bars. Production of hot pressed samples has been made simpler and abundant samples are being produced. 9author
