The Kirkendall effect is the motion of the interface between two metals that occurs as a consequence of the difference in diffusion rates of the metal atoms. The effect can be observed for example by placing insoluble markers at the interface between a pure metal and an alloy containing that metal, and heating … Meer weergeven The Kirkendall effect was discovered by Ernest Kirkendall and Alice Smigelskas in 1947, in the course of Kirkendall's ongoing research into diffusion in brass. The paper in which he discovered the famous effect was the … Meer weergeven Early diffusion models postulated that atomic motion in substitutional alloys occurs via a direct exchange mechanism, in which … Meer weergeven The Catalan Institute of Nanotechnology in Bellaterra, Spain has developed a chemical process creating hollows in nano … Meer weergeven One important consideration deriving from Kirkendall's work is the presence of pores formed during diffusion.
