✦ Synopsis

Combinatorial methods initially applied in pharmacological research are being increasingly used in the development of inorganic materials and polymers. These methods require the creation of large libraries of materials with compositions varying in wide ranges, which are scanned for the desired properties using fast micro or ultramicro characterisation techniques. This approach is particularly adequate for the systematic scrutiny of complex systems, aiming to find unsuspected materials with outstanding properties for particular applications, but its application to metallic and composite materials for mechanical applications has been restrained by the difficulty in preparing suitable libraries, because the presently available preparation methods do not allow a dependable assessment of microstructure-dependent properties. Previous work showed that laser cladding with computer controlled variable powder feed rate is an extremely powerful technique for rapid alloy composition scanning (rapid alloy prototyping). In the present paper, this technique will be briefly described and its application to combinatorial materials science illustrated. 31.1 Recently, combinatorial methods, initially employed in the pharmacological research [1], have been applied to new materials discovery with considerable success. Combinatorial methods require the creation of large libraries of materials with com-290
