  • DIRECTIONAL RECRYSTALLIZATION PROCESSING OF ADDITIVELY MANUFACTURED METAL ALLOYS
    Publication number: 20250162036
    Abstract: A method and apparatus used in preparing a recrystallized metal alloy involve a cooling medium and a heating element to create a cold zone and a hot zone. An additively manufactured metal alloy preform is drawn in a draw direction from the cold zone towards the hot zone to form the recrystallized metal alloy. The cold zone and the hot zone create a surface temperature gradient on at least a portion of the preform of at least about 104 K m?1. The step of drawing causes an average grain size of at least a portion of the preform to increase in a direction parallel to the draw direction.

  • Additive manufactured interpenetrating phase composite
    Patent number: 11325206
    Abstract: A method for preparing metal/metal interpenetrating phase composites is provided. The method includes forming a preform using additive manufacturing. The preform defines a materially continuous three-dimensional open-cell mesh structure. The preform includes a first metal having a melting point. The method further includes pre-heating the preform to a first temperature less than the melting point of the first metal. The method includes infiltrating the preform with a second metal in liquid form. The second metal has a melting point lower than the melting point of the first metal. The method also includes allowing the second metal to cool and form a solid matrix. The solid matrix defines a continuous material network.
