1. Efeito da adição de carboneto de silício em pó na geração de microtrincas e na topografia da superfície na usinada por descargas elétricas do aço-rápido ABNT M2 / Effect of the addition of silicon carbide powder on the microcrack generation and on the surface topography in electrical discharge machining of ABNT M2 high speed steel,
This work investigates surface topography and microcrack generated by electrical discharge machining in workpieces of high speed steel (ABNT M2). Three different commercial dielectric fluids are used with and without addition of silicon carbide powder. Electrodes of electrolytic copper are used in roughing operations. The microcracks are evaluated using SEM

2. Estudo da laminação a quente do aço rapido ABNT M2
In this work, the behaviour of M2 high speed steel during hot rolling, was studied. Both qualitative and quantitative characterization was undertaken of the carbides present before and immediatelyafter true strains sufferedby the material due to hot rolling. For this characterization the techniques of optical and scanning electron microscopy, X-ray diffracti
