Description
Thin films of aluminum mixed with molybdenum can be far harder than plain aluminum. The authors made such films with molybdenum content up to about ten percent, using a sputtering method that deposits both metals at once. They studied the films with X-ray and microscope tools and tested hardness by pressing a tiny tip into the surface. Some molybdenum atoms dissolved inside the aluminum crystals. The rest gathered at the borders between crystals, more strongly as the content rose.
No new compounds formed in any film. As molybdenum increased, the crystals grew smaller and the hardness climbed from 2.2 to 4.9 gigapascals. The team split the gain into parts: finer grains gave the largest share, over sixty percent. Dissolved atoms gave about thirty percent, and a pinning effect of atoms in tiny crystals gave the rest. The study explains why these alloy films strengthen as they do.
