... N 4 ) , as a sintering aid, was rapidly consolidated using P 2 C ® to inhibit grain growth and ensure high strength and ductility of the consolidated material. The consolidated specimens were 93.5% of theoretical density. The microstructure of the consolidated material was characterized using...
