Abstract:
Cutting elements for earth-boring tools comprise a substrate including at least one material selected from the group consisting of CoCr, CoCrMo, CoCrW, and Ti. A polycrystalline superabrasive material may be attached to the substrate. Earth-boring tools comprise a body. At least one cutting element is attached to the body. The at least one cutting element comprises a substrate including at least one material selected from the group consisting of CoCr, CoCrMo, CoCrW, and Ti. A polycrystalline superabrasive material may be attached to the substrate. Methods of forming cutting elements for earth-boring tools comprise disposing a substrate including at least one material selected from the group consisting of CoCr, CoCrMo, CoCrW, and Ti in a container. Particles of superabrasive material may be disposed in the container. The particles of superabrasive material may be sintered with the substrate in the container to form a polycrystalline superabrasive material attached to the substrate.
