To provide a diamond aggregation that can be adapted to process all materials including iron, does not occur in phase transformation acceleration to graphitization by binder, and can be produced at the cobalt-based diamond sintered body (PCD) manufacturing condition generally at present.SOLUTION: The present invention provides a diamond-boron composite aggregation that can be used to ferrous material processing such as various steel materials by using, as binder, boron instead of a conventional ferrous metal such as cobalt having catalysis to graphitization of diamond, and boron carbide that is high melting point substance, in creating of high hardness diamond aggregation.SELECTED DRAWING: None 【課題】本発明は、鉄を含むすべての材料の加工への適用が可能であり、結合材によるグラファイト化への相転換促進も生じず、さらに現在一般的なコバルト系ダイヤモンド焼結体(ＰＣＤ)製造条件で製作が可能なダイヤモンド集合体を提供することを課題とする。【解決手段】高硬度ダイヤモンド集合体の作成において、結合材として、ダイヤモンドのグラファイト化への触媒作用を持つ従来のコバルト等の鉄系金属や、高融点物質であるボロンカーバイドに代えてホウ素を用いることにより、各種鋼材等、鉄系材料加工への利用が可能なダイヤモンド−ホウ素複合集合体を提供する。【選択図】 なし
