Additive manufacturing (AM) constitutes the new paradigm in materials processing and its use on metals alloys opens unforeseen possibilities, but is facing several challenges regarding design of microstructure, which particularly awkward case functional materials, like shape memory (SMA), as they require a robust microstructure to withstand constraints appearing during their change. In present work, attention focused AM important Fe-Mn-Si-based SMA family, attracting great technological...
This work has focused on the study of hot working behavior Ti-Nb microalloyed steels with high Ti contents (> 0.05%). The role Nb during deformation low carbon is well known: it mainly retards austenite recrystallization, leading to pancaked microstructures before phase transformation and refined room temperature microstructures. However, design rolling schedules that result in properly conditioned microstructures, necessary develop models take into account effect concentrations...
Reducing hot cracking is essential for ensuring seamless production of nickel superalloys, which are extensively used in welded structures aircraft engines. The prevalence precipitation-strengthened alloy 718 primarily governed by two factors: firstly, the chemical composition and coarse microstructure formed during solidification, secondly, activation mechanisms, particularly critical mushroom-shaped welding morphologies. In this study, different nickel-based superalloys using laser beam...
In recent years, steels microalloyed with high Ti levels have received increasing attention due to the interesting combination of strength and formability because dispersion nanometric sized titanium carbides that can be formed within matrix. However, one problems related these compositions is their performance highly sensitive variations in processing route. To study this, this work coiling simulations were performed by dilatometry tests a reference Nb steel (0.03%Nb) high-Ti...
