Abstract
It is not economically advantageous to recycle iron and steel products via siderurgy or foundry for the manufacture of small parts. An alternative process for this is the reuse of ferrous metals through the Powder Metallurgy technique. Among the various stages of the processing of materials from particulate materials, the compaction is fundamental for a previous structural consolidation of the bulk. In the present work compact SAE 1050 steel chips from dry turning were produced under pressure up to 3000MPa. The high densification presented in them showed that it is possible to obtain microstructures typical of the final stage of sintering without the use of temperature and consequently the reduction of costs for the manufacture of small parts in industrial scale and of interest for the automotive, electronics and aerospace industry.
