An additive manufacturing process that includes providing a first layer of powdered material having a predetermined thickness; using a laser beam that follows a predetermined path to fuse a portion of the material in the first layer, wherein the predetermined path of the laser beam is a repeating circular or elliptical path which incrementally proceeds in a linear direction; providing a second layer of powdered material having a predetermined thickness; using a laser beam that follows a predetermined path to fuse a portion of the material in the second layer, wherein the predetermined path of the laser beam is a repeating circular or elliptical path which incrementally proceeds in a linear direction; repeating the previous steps until a complete part or component is created; and removing any unfused powdered material from the completed part or component.

A method for fabricating assemblies that includes providing a first component that further includes silicon carbide and that has an upper portion and a tapered lower portion; providing a second component that further includes silicon carbide and that has an upper portion that is adapted to receive the tapered lower portion of the first component; providing a predetermined amount of multiphase Al&#x2014;Si braze foil; grinding the Al&#x2014;Si braze foil into a powder; mixing a predetermined amount of braze paste binder with the Al&#x2014;Si powder to form a slurry; uniformly applying the slurry to the tapered lower portion of the first component; uniformly applying the slurry to the upper portion of the second component and inserting the tapered lower portion of the first component into the upper portion of the second component; and heating the applied slurry to a temperature of 725&#xb0; C. to 1450&#xb0; C. for a predetermined period of time.
