1. Furação de ferros fundidos austemperados e nodular perlítico / Machinability of Austempered Ductile Irons and Pearlitic Ductile Iron in Drilling Process
Many materials have mechanical proprieties improved by heat treatments, but this can cause changes in the structure of the material, worsening its machinability, as in the case of austempered ductile iron (ADI) that despite of presenting better mechanical proprieties it has lower machinability when compared with the conventional ductile iron and steel of sim

2. Residual analysis applied to S-N data of a surface rolled cast iron
Surface rolling is a process extensively employed in the manufacture of ductile cast iron crankshafts, specifically in regions containing stress concentrators with the main aim to enhance fatigue strength. Such process hardens and introduces compressive residual stresses to the surface as a result of controlled strains, reducing cyclic tensile stresses near

3. The effect of surface rolling on fatigue behavior in a pearlitic ductile cast iron / "Influência do roleteamento no comportamento em fadiga de um ferro fundido nodular perlítico"
Surface rolling is a mechanical treatment commonly used in parts fabricated with steel and ductile cast iron, specifically in stress concentration regions, to improve fatigue properties. This process hardens and introduces compressive residual stresses to the surface of the material through the application of controlled strains, thus provoking a reduction of
