NACA Technical Notes

Report presenting an investigation of the sintering of chromium carbide under pressure in order to study the kinetics of grain growth and densification during this process. Densification of a sintered chromium carbide compact was accompanied by grain growth and density and grain size seem to be interdependent during this stage of the sintering process

NACA Technical Notes

Report presenting an investigation of the sintering process and sintering mechanism of a zirconium carbide-columbium ceramal. Results regarding the study of the bonding specimen and study of the sintering specimens are provided

NACA Technical Notes

Report presenting an investigation to determine the properties of a boron carbide-iron ceramal. The properties were compared to the properties of hot-pressed boron carbide. The properties evaluated were room- and elevated-temperature modulus of rupture, resistance to fracture by thermal shock, density, and oxidation characteristics

NACA Technical Notes

Report presenting an investigation to study the influence of structural variations on the properties of chromium carbide sintered under pressure. The results show that the room-temperature strength and hardness are influenced by the stages of sintering, which are defined by grain size and by the number, size, location, and shape of pores
