In a previous work a M3:2 high speed steel was vacuum sintered from irregular water atomized powder and had its sintering temperature determined. In this work the same powder was uniaxially cold compacted and vaccum sintered by adding some small quantity of carbon (0.3% in weight) to prevent porosity and loss of carbon which result from the sintering cycle. The sintered samples from all these experimental procedures had their density evaluated. The microstructure was evaluated using optical-electronic techniques in order to investigate the best range of sintering temperature. At least five parallel samples were tested to each condition of sintering.Resumo IPEN-doc 11069 Carbide size and bend strength of M3-2 high speed tool steels2005 - ARAUJO FILHO, O.O.; RIBEIRO, O.C.S.; NOGUEIRA, R.A.; LIBERATI, J.F.; MUNIZ, L.F.; AMBROZIO FILHO, F.
