Summary: This study investigated the glass-forming range, microstructural features, and soft magnetic properties of (Fe(1-x-)yCo(x)Ni(y))(86)B-14 alloys. It was found that Fe-rich compositions have the largest glass-forming range and exhibit nano-scale grains with bcc and fcc structures after ultra-rapid annealing. The coercivity and saturation magnetic polarization of the nanocrystalline alloys are affected by Co and Ni content, with Co addition generally increasing coercivity and saturation magnetic polarization, while Ni addition has the opposite effect.

Summary: Ultrafine grained metals and metal matrix nanocomposites with enhanced strength and good tensile ductility can be successfully fabricated through processing and consolidation techniques. The synergistic effects of grain boundary strengthening and intragranular nanoparticles play a crucial role in improving the material's performance, while heterogeneous microstructures introduce additional boundaries between hard and soft regions to enhance strength without sacrificing ductility.

Summary: This study focuses on the Al0.8CrFe2Ni2 high entropy alloy fabricated using laser powder bed fusion with pre-alloyed powder. Heat treatment of the as-built material resulted in a dual-phase microstructure composed of face-centered-cubic grains and Al-, Ni-rich body-centered-cubic B2 precipitates. The effects of heat treatment on the alloy's properties were explored through microstructure characterization, mechanical, and corrosion testing. The results demonstrate that mechanical properties can be tailored by controlling the size of precipitates through heat treatment. Refining the precipitates improves strength without significant loss of ductility. Corrosion tests show that the as-built samples display better overall corrosion resistance compared to heat-treated samples, attributed to the influence of precipitates on micro-galvanic cell formation.

Summary: Metallic glasses have short-range order but lack long-range order. The short-range order is mostly found in dominant clusters with higher local order metrics, while medium-range order is mainly represented by Bergman-type order centered on icosahedral clusters. With increasing length scale, the correlation between neighboring atoms decreases, including the icosahedral cluster network.

Summary: The present study investigates the oxidation behavior of nanocrystalline (NC) and microcrystalline (MC) Fe-20Cr-5Al alloys at 900 degrees C. The results show that nanocrystallization reduces the Al requirement for the formation of a protective Al2O3 layer, leading to a significantly lower oxidation rate compared to microcrystalline alloy. Additionally, the microcrystalline alloy exhibits a higher weight gain than the nanocrystalline alloy.

Summary: The relationship between microstructure and mechanical properties in Ni-free high N transformation induced plasticity steels at room temperature was studied in this work. Tensile properties were influenced by the Mn content and transformation routes, affecting strain hardening rate and ductility. The formation of martensite before plastic deformation reduced strain partitioning and load transition, while higher strain compatibility between austenite and ferrite resulted in improved uniform elongation and moderate strain hardening rate in the alloy with higher Mn content.

Summary: Tailoring the microstructure of additively manufactured metal parts by adjusting process parameters reduces the need for post-treatments and leads to cost and production steps reduction. This study investigates the effects of scanning patterns on microstructures and hot tensile behavior of a laser powder-bed-processed Hastelloy X Ni-based superalloy. The results show that the island scanning pattern produces superior tensile properties at high temperatures due to its larger grain and cell sizes compared to the meander pattern.

Summary: The effect of N addition on solidification behavior and microstructural features of the cast and HIPed Ti-48Al-2Cr-2Nb alloy was studied. The results showed that N addition changed the morphology of the primary phase dendrites and improved the uniformity of the microstructures. Furthermore, N addition led to the formation of primary Ti2AlN precipitates within lamellar colonies and increased microstructure stability during HIPing. N addition also decreased the formation of a duplex structure and promoted the formation of secondary Ti2AlN precipitates at lamella interfaces.
