1. EFFECT OF HEAT TREATMENT ON MICROSTRUCTURE AND MECHANICAL PROPERTIES OF TOOL STEELS FOR COLD WORK APPLICATION / "Efeito do tratamento térmico na microestrutura e nas propriedades mecânicas de aços-ferramenta para trabalho a frio"
Tool steels have important participation in the worldwide market of steels. They are used by metal-mechanical industry as cutting tools, molds, punches, dies etc.Due to the use of great responsibility, it is important to discuss the relationship between microstructure and mechanical properties because it is a common practice in industry to specify heat treat

2. Obtenção de revestimentos dúplex por nitretação a plasma e PVD-TiN em aços ferramenta AISI D2 e AISI H13. / Duplex coatings on AISI H13 and AISI D2 tool steels by using plasma nitriding and TiN-PVD.
In this work, the influence of both the microstructure and the load-bearing capacity of nitrided layers, formed on top of AISI D2 and AISI H13 tool steels, on adhesion and wear resistance of PVD-TiN coatings was studied. The threshold nitriding potential curves for the above mentioned steels and the optimum conditions of the pre-treatments which increased th
