Abstract
A gradient material is manufactured in which the alloy composition varies continuously with the cross-section. A first metal liquid is introduced from a first tundish into the outer portion of a water-cooled mould. A second metal liquid is introduced into the inner portion of the water-cooled mould through a refractory entry nozzle immersed in the first metal liquid to form a metal liquid pool. The metal liquid pool is solidified into an ingot where the composition of alloys varies continuously from the inside to the outside of the ingot.
