摘要： Thermally-stable polycrystalline diamond materials of this invention comprise a first phase including a plurality of bonded together diamond crystals, and a second phase including a reaction product formed between a binder/catalyst material and a material reactive with the binder/catalyst material. The reaction product is disposed within interstitial regions of the polycrystalline diamond material that exists between the bonded diamond crystals. The first and second phases are formed during a single high pressure/high temperature process condition. The reaction product has a coefficient of thermal expansion that is relatively closer to that of the bonded together diamond crystals than that of the binder/catalyst material, thereby providing an improved degree of thermal stability to the polycrystalline diamond material.

摘要： A braze alloy is described which includes indium and/or thallium as alloying elements. For example, between about 0.5% and about 10% by weight of indium (In) and/or thallium (Tl) can be added to a braze alloy to reduce the braze temperature without substantially effecting braze strength. Braze alloys that are alloyed to including indium (In) and/or thallium (Tl) can be use in brazing cutting elements to drilling tools. These alloying elements may also be added to braze alloys used for other applications to reduce braze temperature.
