Rare Earth Additions

The effect of rare earth additions on diffusion and porosity deformation of Al-11Si-Cu alloy was investigated. The microstructure was characterized by optical microscope. By adding small amount of La and Ce, the porosity can be reduced. As the amount of La and Ce were increased, the porosity defects were diffused and increased in microstructure. RE intermetallic indicates Al-Cu phase interrupted the quality of Al-Si-Cu casting alloy.

The Rare Earth

A method of analysis is proposed which utilizes thecharacteristic melting points of the hydrated salts andthe liquidus curves of the binary salt mixtures for theestimation of the composition of rare earth mixtures.Several binary salt systems were investigated, employingvery pure simple and double rare earth nitrates toprovide basic information concerning the possibilitiesof the method.
