Materials and methods: In this cross-sectional study, 55 patients with idiopathic PD by mean age of 59.85 ± 11.89 years, and mean Hoehn and Yahr stage ...
The grain size refinement of AISI 422 martensitic stainless steel in the temperature range of 950-1150 ºC was investigated by hot deformation tests. The deformed specimens were held at deformation temperature with delay times of 5 to 300s after achieving a strain of 0.3. The austenite grains exhibit a considerable growth at temperature higher than 1050˚C, while the grain coarsening is negligibl...
