The present project proposal aims the application of the study of the TWIP and TRIP phenomena (FAPESP 19/07178-6) to develop heterogeneous structures in face-centered cubic materials. Two configurations are proposed: 1) Study and modeling of structural gradients induced by deep burnishing on austenitic stainless steels; 2) Study of lamellar structures obtained by accumulative roll bondin…
The project focuses on the development of advanced ultrafine-grained magnesium alloys for biodegradable load-bearing applications in Medicine. Two techniques of severe plastic deformation, namely high-pressure torsion and equal channel angular pressing will beemployed to produce the ultrafine-grained structure. Mg-Zn-Ca and Mg-Li-Y systems containing biocompatible elements are selected as…
The occurrence of strain-induced martensitic transformation (TRIP effect) and mechanical twinning (TWIP effect) increases the strain hardening and the total elongation of CFC alloys with medium and low stacking fault energy (SFE) thus providing higher strength and tenacity to these materials. The technological advantages of these effects are: (i) the higher ductility allows the conformati…
Microdrawing and micromachining are two advanced fabrication processes of a component in which at least two dimensions are below the millimetre. With such a reduced scale, the plastic and elastic anisotropies of coarse grained materials are very important, since they cause enhancement of crystallographic texture and deformation heterogeneity much larger than when the material has a small …
Severe plastic deformation methods applied on metals and alloys activate grain reduction mechanisms, which on their turn result in intense increase of mechanical strength. Moreover, those methods promote change in the original crystallographic texture. We intend to initiate a research line on this topic using two severe plastic techniques, viz, equal channel angular extrusion, and asymmet…

Samples of a roll cast AA1050 alloy will be asymmetrically rolled using a modified roll mill, where the upper and lower roll has a diameter rate of 1,4. The same material will be extruded by an equal channel angular pressing (ECAP) matrix with an internal angle of 120o and inner dimensions of 7 x 40 mm. The deformation heterogeneity will be evaluated by micro hardness measurements. After …
