Abstract
A drill bit may include a matrix bit body and a plurality of cutting elements coupled to an exterior portion of the matrix bit body, wherein the matrix bit body includes matrix particles and precipitated intermetallic particles dispersed in a binder, at least some of the matrix particles having a diameter of 50 microns or greater, and at least some of the precipitated intermetallic particles having at least one dimension of 1 micron to 30 microns.
Claims8
A drill bit comprising:
- a matrix bit body having matrix particles and precipitated intermetallic particles dispersed in a binder, at least some of the matrix particles having a diameter of 50 microns or greater, and at least some of the precipitated intermetallic particles having at least one dimension of 1 micron to 30 microns;
- and
- a plurality of cutting elements coupled to an exterior portion of the matrix bit body,
- wherein the matrix particles include first matrix particles having a diameter greater than or equal to five microns and second matrix particles having a diameter less than five microns, and
- the second matrix particles are less than 5% by weight of a total of the first matrix particles and the second matrix particles.
