14. Desenvolvimento de acabamento rolled-on em aço inoxidável
Different kinds of finishes exist for steels, a new one known Rolled-On (RO) could show with different surfaces patterns, with different roughness and gloss. This work presents the development of the RO finishes in 439 stainless steel with 1,5mm thick. This new finishes will be produced to substitute the grindings finishes. A RO finishes is obtained using a

18. The Influence of the Austenitizing Temperatures for Quenching and Tempering on the Toughness and Fatigue Life of SAE 5160 Steel with Different P Contents / Influência da temperatura de austenitização para têmpera e de revenimento na tenacidade e na vida em fadiga do aço SAE 5160 para diferentes teores de fósforo
The aim of this work was to analyze the influence of austenitizing and tempering temperatures on the impact and fatigue life of the SAE 5160 spring steel, considering two different P amount. Bars (70 x 10 mm) were heat treated using three different austenitizing temperatures, 850ºC, 900ºC and 1000ºC, with a 15 min furnace soaking time. The quenching tempe

19. Definição da metodologia da caracterização da temperabilidade de vidros planos finos
The tempering of glass can substantially increase its resistance to mechanical shock. Tempered thin glass, compared to tempered thick glass, is more susceptible to spontaneous fracturing. During the tempering process, the glass is heated above the transition temperature (Tg) and below its melting point (melting temperature for silica vitrea is 1750 C). The s

22. Desgaste e fadiga térmica de ligas aço matriz + NbC. / Wear and thermal fatigue of matrix steel + NbCalloys.
The concept of ?matrix steel + NbC? was used to cast alloys with the M2 steel matrix (0,5%C ? 2%W ? 3%Mo ? 4,6%Cr ? 1%V) and different volume fractions of niobium carbides. Niobium (2,5 e 5%) and stoichiometric carbon were added to produce NbC carbides and titanium (0,1%) to modify de NbC carbides morphology. NbC presented three basic morphologies: Chinese s

24. CORRELAÇÃO ENTRE MICROESTRUTURA E PROPRIEDADES MECÂNICAS EM METAL DE SOLDA COM DIFERENTESTEORES DE MN, SUBMETIDO A TRATAMENTOS TÉRMICOS / MICROSTRUCTURE AND MECHANICAL PROPERTIES CORRELATIONS FOR HEATTREATED STEEL WELD METALS WITH DIFFERENT MN CONTENT
Traditionally, both Cr-Mo class steels and the weld metals produced in joining such materials have been considered to be susceptible to the phenomenon of temper embrittlement. The current study evaluates 2,25%Cr-1,0%Mo type weld metals with varying Mn levels (0,4%- 1,1%), produced using coated electrodes with an SMAW process. The welded joints were subjected
