The Incremental Melting and Solidification Process (IMSP) is a relatively new field formaterial processing for the production of functionally graded materials. In this process a controlledliquid bath is maintained at the top of the component where new materials are added changing thecomponents composition. Thus, a functionally graded material is obtained with a varyingcomposition along one direction of the component. This paper deals with the influence of one of theprocess parameters, namely displacement rates between heating coil and mould, in order to evaluateits influence on both metallurgical and mechanical properties of different Al-Si alloys. Hardness andphase distribution, along the main castings axis, were measured. To better assess and characterizethe process, two different Al-Si alloys with and without variation of chemical composition along thespecimen were analysed. Results demonstrate that a gradual variation of metallurgical andmechanical properties along the component is obtained. It is also shown that Al-Si functionallygraded materials can be produced by the incremental melting and solidification process. Resultsshow that the displacement rate is very important on metallurgical and mechanical properties of theobtained alloy
