摘要： An abrasive article configured to grind a workpiece having a fracture toughness of less than about 6 MPa-m½ includes a body comprising abrasive particles contained within a bond material comprising a metal, wherein the body comprises a ratio of V
AG /V
BM of at least about 1.3, wherein V
AG is a volume percent of abrasive particles within a total volume of the body and V
BM is a volume percent of bond material within the total volume of the body, and wherein the abrasive particles have an average particle size of 1 to 45 microns.
