A Versatile Three Dimensional Printing Approach

Several design challenges have hindered use of conductive materials in commercial 3D printing. One such obstacle is the heating requirements for formation of an object to be fabricated using a 3D printing approach. Conductive materials and additives often have relatively high melting temperatures,...

Abnormal Grain Growth Suppression in Aluminum Alloys

Heat treatment of the deformed welds is desirable in order to restore the properties of the alloy negatively affected in the weld region. In these alloys, abnormal grain growth frequently occurs in friction stir welds during solution heat treatment, and is known to degrade key materials properties...
