Abstract
The precipitation process in a Cu-2.5 pct Fe alloy was studied experimentally by means of X-ray diffraction and hardness measurements and light and electron microscopic observations. It was concluded that γ-Fe and α-Fe precipitate simultaneously, γ-Fe dominating in the early stages. During later stages, the particles of γ-Fe dissolve, providing the copper lattice with iron atoms which diffuse to the more stable α-Fe particles. The α-Fe particles continue to grow until all evidence of the γ-Fe is gone.
