Concurrent Growth of Kirkendall Pores and VaporSolid

Abstract. During vapor-phase deposition at 1273 K (1000 °C), by pack cementation, of Mo onto 127-m-diameter Ni wires, two phenomena are observed to occur concurrently, leading to strong surface roughening:(i) the inward radial growth of Kirkendall pores below the wire surface and (ii) the outward growth from the wire surface of protuberances with sizes as large as 15 m.
