1. The flow behavior modeling of as-extruded 3Cr20Ni10W2 austenitic heat-resistant alloy at elevated temperatures considering the effect of strain
In order to investigate the compressive deformation behavior of 3Cr20Ni10W2 alloy, a series of isothermal upsetting experiments were carried out in the temperature range of 1203-1403 K and strain rate range of 0.01-10 s-1 on a Gleeble-1500 thermo-mechanical simulator. The results indicate that the flow stress initially increases to a peak value and then decr

2. Transient solidification of alloys of the monotectic AI-Bi, AI-Pb and AI-In systems / Solidificação transitória de ligas dos sistemas monotéticos AI-Bi, AI-Pb e AI-In
Aluminum alloys dispersed with bismuth, lead and indium show promising applications in wearresistant automotive components. Such dispersions of low melting temperature elements decrease hardness and flow easily under sliding conditions, resulting in favorable tribological behavior. Much research has been devoted in order to better comprehend the distinct m

3. Caracterização microestrutural da decomposição de carbonetos eutéticos M2C em ferro fundido multicomponente do tipo Fe-2C-5V-5Cr-5Mo-5W tratados isotermicamente à 950ºC e 1.050ºC. / Microstructural characterization of M2C eutectic carbides decomposition in multicomponent cast iron of type Fe-2C-5V-5Cr-5Mo-5W isothermically heat treated at 950°C e 1.050°C.
Multicomponent White Cast Iron are high temperature wear resistant ferrous alloys, presenting eutectic MC and M2C carbides in their as cast structure. In the present work the decomposition microstructures of the metastable M2C carbide after heat treatments was characterized in a model multicomponent white cast iron with composition (in weight): 2 wt% C and 5

4. Solidification microstructures and mechanical and corrosion resistances of dilute Pb-Sn alloys / Microestrutura de solidificação e resistencias mecanicas e a corrosão de ligas Pb-Sn diluidas
Lead-acid batteries manufacturers have modified the manufacturing processes and the chemical composition of alloys used in battery grids in order to decrease their weight as well as to reduce the production costs, and to increase the battery life-time cycle and the corrosion-resistance. The morphological microstructures characterized by cellular and dendriti

5. Caracterização do envelhecimento da liga 20Cr32Ni+Nb fundida por centrifugação e de seu efeito sobre o comportamento mecânico a frio. / Characterization of aging in centrifugally cast alloy 20Cr32Ni+Nb and its effects on mechanical behavior.
Fornos petroquímicos constituem a parte mais importante da indústria de derivados de petróleo. São nesses fornos que se processam as reações químicas imprescindíveis ao processamento dos produtos que constituem nosso cotidiano, como os fertilizantes, polímeros, produtos farmacêuticos e alimentícios. Devido ao caráter fortemente endotérmico dos p
