A method includes disposing a braze material between a first body and a second body. The braze material includes a first composition and a second composition. The second composition has a melting point higher than the first composition. The braze material may be heated to a brazing temperature between the melting points of the first and second materials and maintaining the braze material at the brazing temperature for a period of time to transform a transient liquid phase to a solid phase, forming a bond between the first body and the second body. A braze material for securing solid bodies includes a first composition and a second composition. The first composition includes at least one element selected from the group consisting of indium, tin, zinc, and magnesium. An earth-boring tool includes a first body, a second body, and a braze material bonding the second body to the first body.
