发明名称 DIAMOND SINTER AND PROCESS FOR PRODUCING THE SAME
摘要 Provided are a diamond sintered body having higher strength and more excellent wear resistance than a conventional diamond sintered body, and a method for producing such a diamond sintered body. The diamond sintered body includes diamond particles, a binder, and a void. The diamond particles have a content of not less than 80 % by volume but less than 98 % by volume. The binder includes a solid solution containing at least one element selected from a group consisting of titanium, zirconium, vanadium, niobium, and chromium, carbon, and tungsten, as well as an iron group element. Neighboring ones of the diamond particles are bonded to one another. The method provides such a diamond sintered body.
