Resumo

Experimental determination of Young's moduli of sintered metal–powder mixtures was carried out with results comparison through the use of a resonant frequency technique (dynamic excitation methodology) and an evaluation of the elastic stress–strain ratio in monotonic tensile loading regime. The materials used in this study consist of sintered bodies obtained from several metallic powders employed in the production of powder metallurgy metal composites used in diamond impregnated tools for cutting hard materials (such as stone cutting). The values of Young's modulus determined experimentally are also analysed and compared with a theoretical estimation carried out considering the chemical composition of each material and applying a simple rule of mixtures. The dynamic excitation is assumed to be the simplest experimental procedure, enabling accurate and reproducible measurements. On the other hand, the microstructure of the sintered bodies seems to influence the values of Young's modulus measured experimentally.
