Summary: The study investigated the influence of Si addition on the microstructure and mechanical behavior of cast silicon stainless steel alloys, revealing significant changes in microstructure and mechanical properties with varying Si content. Si incorporation improved strength and ductility in primarily austenitic microstructure, but higher Si content led to a duplex structure and reduced ductility. Nanoindentation characterization suggested significant improvements in hardness and modulus of the austenite phase after Si incorporation. Further analysis indicated a correlation between mechanical properties and crystallographic orientation of grains, showing highly anisotropic behavior. Lastly, nanomechanical properties were used to predict bulk mechanical properties with ECM model, highlighting the need for refined models for materials with duplex microstructure.

Summary: The crystal orientation of Ni50Mn25In25 and Ni50Mn34In16 melt-spun ribbons, which exhibit parent phase at room temperature, was investigated in this study. The grains were found to grow perpendicular to the ribbon's surface, showing distinct columnar crystals. X-ray diffraction and electron backscattered diffraction techniques were used to identify the orientation information. The results indicate a well-developed preferred orientation parallel to the direction, in accordance with the Eucken-Hirsch texture observed in other shape memory ribbons. This texture is predicted to be beneficial for magnetic field-induced strain compared to common polycrystals. The findings of this study provide a reference for the preparation of Ni-Mn-In melt-spun ribbons.

Summary: This study investigated the role of slip and twinning in strain hardening of titanium. The microstructure and texture evolution were studied using electron backscattered diffraction. The strain hardening was categorized into multiple stages, controlled by twin-induced geometrical hardening and softening, latent hardening, and grain boundary strengthening. Crystal plasticity was used to simulate flow curve and texture evolution, observing slip and twin activities. Compression favored prismatic < a > slip and extension twin (ET) evolution. ET nucleated at e = 0.10 and expanded to almost the entire microstructure at e = 0.22. ET reoriented the microstructure to a geometrically hard orientation, increasing the Taylor factor (M). ET led to sigmoidal flow behavior and increased strain hardening rate (SHR) in stage II. The dominant deformation mechanisms in ET domains were pyramidal < c + a > and basal slips, producing a fiber texture. Contraction twins (CT) also evolved inside ET domains beyond e = 0.11, reorienting the texture to a softer orientation with a low M. The geometrically soft CT domains, latent hardening, and grain fragmentation contributed to the flattening of the strain hardening curve and decreasing SHR in stage III after e = 0.17.

Summary: Slow strain rate tests on hydrogen-containing specimens of PH13-8Mo maraging stainless steel revealed H-assisted subcritical quasi-cleavage cracking, which accelerated material failure. Fractographic analysis showed that quasi-cleavage consisted of flat brittle areas and rougher areas. Electron backscatter diffraction (EBSD) testing on a secondary subcritically grown crack revealed significant crystal lattice rotation and consequential plastic deformation concentrated between the main crack tip and the cracks located ahead of it. Quasi-cleavage consisted of {100} cleavage cracks connected by ductile ridges, suggesting a discontinuous mechanism involving the re-initiation of new cleavage cracks ahead of the main crack tip.

Summary: This study systematically investigated the effects of quenching temperatures on the microstructure and mechanical properties of high-strength micro-alloyed steel during a novel designed austenitising bending process. The results showed that satisfactory parts with desired shapes could be bent without spring-back and cracks at bending temperatures of 850-1000 degrees C. The decrease in strength with increasing bending temperature was attributed to the integrated influences of high temperature dynamic recovery and dynamic recrystallisation. The distribution of hardness was determined by dislocation pile-ups and the position of stress neutral layer in the plate.

Summary: Extensive research has been conducted on high entropy alloy composite coatings reinforced with micro-sized ceramic particles at room temperature. However, studies on their properties at high temperatures are limited. This study investigated the oxidation and tribological properties of CrMnFeCoNi/xTiC composite coatings produced by laser cladding at a temperature of 600 degrees C. The addition of TiC promoted the oxidation process and the formation of a wear-resistant intermediate layer. The coatings exhibited low hardness, low wear rate, and high coefficient of friction due to the formation of a composite oxide film on the worn surface with good adhesion to the matrix.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.
