Peritectic transformation
Journal Article

· Acta Metall.; (United States)
Some experimental observations on the Al-Al/sub 3/Ti and Cd-Cd/sub 3/Ag peritectic systems are discussed in relation to transformation rates. In steady-stage unidirectional solidification equilibrium between the solid and liquid phases is closely approached at all points of the solid-liquid interface. An approximate diffusion analysis permits prediction of the rate of growth of the peritectic envelope by diffusion through the envelope. In the Al-Al/sub 3/Ti system the peritectic product is formed principally by direct transformation from the liquid phase, and attack on the properitectic phase is minimal. In the Cd-Cd/sub 3/Ag system the peritectic transformation goes almost to completion, and direct transformation from the liquid plays a minor part.
