Ciência & Tecnologia dos Materiais is the official journal of SPM, the Portuguese Society of Materials (Sociedade Portuguesa de Materiais), providing a forum for publishing peer-reviewed papers related to both fundamentals of materials science and technological application of engineering materials. The scope of the journal covers a wide range of topics in materials science that are of interest to the SPM, encompassing electrochemistry, corrosion and protection of materials, extractive metallurgy and recycling, electronic and optoelectronic materials, biomaterials, forest materials, polymeric and composite materials, foundry, heat treatment and surface engineering, tribology, and fracture. Science and Technology of Materials welcomes contributions in the form of original research papers, review articles and technical notes reporting advances on those fields, emphasizing new materials, new products and devices, and new technologies.

Proper waste handling and sustainable recycling approaches are emerging topics for environmental safety and ecomanufacturing technologies. Steel chips resulting from new machining procedures are good candidates as new raw material for innovative recycling approaches due to their unique characteristics. The objective of this study was to characterize as-quenched H13 (AISI- SAE) tool steel chips produced by a machining procedure. Microhardness tests, SEM/EBSD and TEM techniques were used for hardness evaluation and microstructural characterization. Chips display a highly strained submicron-nanocrystalline grain structure with hardness up to 6.2GPa. Such characteristics suggest the chips are suitable for powder manufacturing processes such as ball milling instead of atomization process.
