Abstract
A device, system and method for nondestructively obtaining qualitative and/or quantitative information relating to the material properties of a region in a diamond body comprises directing x-rays onto the body. The body can comprise sintered or unsintered diamond. The body can ultimately be in the form of a cutting element used with a subterranean drill bit. The x-rays penetrate the body and cause a target element within the desired region including the same to emit x-ray fluorescence. The emitted x-ray fluorescence is received and information relating to content, location, and/or distribution of the target element in the region within the body is determined therefrom. The measured region can extend axially or radially from a surface of the body, and the target elements are nondiamond materials that can be constituents of a substrate attached to the body, or of a container used during HPHT sintering of the body.
