• Diffusion welding — Animation of the Diffusion Welding process Diffusion welding (DFW) is a solid state welding process by which two metals (which may be dissimilar) can be bonded together. Diffusion involves the migration of atoms across the joint, due to… …   Wikipedia

• Atomic diffusion — is a process whereby the random thermally activated hopping of atoms in a solid results in the net transport of atoms. For example, helium atoms inside a balloon can diffuse through the wall of the balloon and escape, resulting in the balloon… …   Wikipedia

• Solid solution strengthening — is a type of alloying that can be used to improve the strength of a pure metal. The technique works by adding atoms of one element (the alloying element) to the crystalline lattice another element (the base metal). The alloying element diffuses… …   Wikipedia
