|Metallic materials such as pure metals or alloys, are mostly polycrystalline in form. Grain boundaries are what influence the materials properties such as the strength, ductility, and electrical conductivity. Nickel is an important metal for both industrial and advanced materials for certain applications. Nickel is difficult to equip with twin boundaries because of its high stacking fault energy. There is a need for a new method to be able to fabricate a new form of nickel which means there is a need for a new method of fabrication.
Researchers at Purdue University have developed a new method of fabrication. This new method is a hybrid technique that can fabricate single-crystal-like, grain boundary-free nickel. This technique involves ultrahigh vacuum and additive-assisted electrodeposition. This allows this hybrid technique to fabricate nickel that has increased flow strength and an increased hardening ability. This new technique opens the door to many new fabrication techniques to strengthen other metals.
