Abstract
Cutting elements for earth-boring tools may include a superhard, polycrystalline material and a substrate adjacent to and secured to the superhard, polycrystalline material at an interface. The substrate may include a first region exhibiting a first coefficient of thermal expansion and a second region exhibiting a second, different coefficient of thermal expansion. The first region may be spaced from the superhard, polycrystalline material. The second region may extend from laterally adjacent to at least a portion of the first region to longitudinally between the first region and the superhard, polycrystalline material.
