Autor: Samuel Filgueiras Rodrigues, Eden Santos Silva, Gedeon Silva Reis, Regina Célia de Sousa, Oscar Balancin

Publikováno v: Materials Research, Vol 17, Iss 2, Pp 436-444 (2014)

An austenitic stainless steel ISO 5832-9 used as a biomaterial was torsion-deformed over the temperature range of 1000-1200 °C and strain rates of 0.05, 0.1, 1.0 and 5.0 s- 1. The flow stress curves obtained showed two regions where firstly there is

Surface integrity analysis when milling ultrafine-grained steels

Autor: Alessandro Roger Rodrigues, Oscar Balancin, Juno Gallego, Cleiton Lazaro Fazolo de Assis, Hidekasu Matsumoto, Fernando Brandão de Oliveira, Suzana Regina da Silva Moreira, Otavio Villar da Silva Neto

Publikováno v: Materials Research, Vol 15, Iss 1, Pp 125-130 (2012)

This paper quantifies the effects of milling conditions on surface integrity of ultrafine-grained steels. Cutting speed, feed rate and depth of cut were related to microhardness and microstructure of the workpiece beneath machined surface. Low-carbon

Prediction of steel flow stresses under hot working conditions

Autor: Alberto Moreira Jorge Junior, Oscar Balancin

Publikováno v: Materials Research, Vol 8, Iss 3, Pp 309-315 (2005)

An austenitic stainless steel was deformed in torsion over a temperature range of 900-1200 °C using strain rates of 1, 5 and 10 s-1. The stress vs. strain curves determined were corrected for deformation heating and the flow stress was found to rise

Influence of deformation on the kinetics of phase transformation in a forging steel during warm working

Autor: Mauro Aparecido Ferreira de Oliveira, Alberto Moreira Jorge Jr, Oscar Balancin

Publikováno v: Materials Research, Vol 7, Iss 2, Pp 247-253 (2004)

Dilatometric techniques were used to determine the start and finish transformation heating temperatures for a carbon steel (0.30% C - 1.5% Mn). The mechanical behavior of the steel was measured by torsion testing in the temperature range of 700 to 82
