Summary: The beta-type and sintered Ti-3.6Fe-5Zr-0.2B alloy was consolidated using spark plasma sintering and followed by a beta solution treatment. Modification of sintering conditions improved the tensile ductility by achieving 100% relative density. Water quenching resulted in the formation of alpha martensite phases, while air cooling suppressed their formation and instead precipitated bimodal alpha lath phases, resulting in higher strength and better ductility.

Summary: The barium aluminosilicate compound (BaAl2Si2O8 or BAS) was synthesized using powder reactive sintering in a Spark Plasma Sintering (SPS) device. The reaction pathways between the precursors (alumina, silica, and barium carbonate powders) were investigated at different temperatures from 900 to 1550 degrees Celsius to obtain the desired hexacelcian crystallographic form of BAS without any unwanted compounds. A three-step thermal treatment was proposed to achieve a fully dense and nearly pure (98 wt%) BAS.

Summary: This investigation examines the microstructure and mechanical properties of TiB2-SiC-graphene ceramics. The results show that the system is unreactive, preventing the in-situ nucleation of B4C and TiC phases. While the presence of TiO2 and B2O3 impurities is reduced with the addition of graphene nano-platelets (GNPs), SiO2 is confirmed to be present in the final microstructure. The TiB2 phase exhibits significantly higher hardness and Young modulus compared to the SiC phase.

Summary: The evolution of microstructure and mechanical properties of AISI 4340 steel during high-energy ball milling, spark plasma sintering (SPS), and post heat treatments was investigated. The study found that high-energy ball milling resulted in the formation of a nanocrystalline (-10 nm) bcc Fe matrix with segregation of alloying elements and oxide particles. The as-sintered alloy consisted of martensite-austenite (MA) constituent and fine pearlite, while the quenching after austenitization formed a microstructure composed of martensite and MA constituent. Tempering induced the decomposition of retained austenite and precipitation of cementite particles. The compressive yield strength of the as-sintered alloy was primarily strengthened by dislocations and grain boundaries/cementite lamellae, as well as secondary strengthening by oxide particles.

Summary: The paper analyzes two compaction methods for obtaining W/Cu Functional Graded Materials (FGMs) consisting of three layers with different compositions. The compaction methods used were Spark Plasma Sintering (SPS) and Conventional Sintering (CS). The samples obtained through SPS showed higher densities compared to the samples obtained through CS. The research recommends using SPS for W/Cu-FGMs due to its superior morphology and fine-graded powders.

Summary: This study utilized the spark plasma sintering (SPS) technique to prepare a Mg-4wt.%Y-3wt.%Nd material (WN43) with outstanding mechanical properties and excellent plastic elongation. By suppressing the detrimental effect of oxide shells on the powder particles, the strong interconnection of the particles was achieved. The material retained the fine powder microstructure and exhibited ductility and strength comparable to conventionally-prepared Mg-RE alloys.

Summary: The study investigated the effect of TiCN on the microstructure development of fully dense ZrB2-based ceramics sintered using spark plasma sintering. The formation of (Zr,Ti)B-2 and ZrCN phases was observed in the final microstructures, indicating a chemical reaction between TiCN and ZrB2. The (Zr,Ti)B-2 matrix in the ternary system exhibited a Vickers hardness of 29.3 GPa and an elastic modulus of 450.8 GPa, with a roughly uniform composition facilitated by SiC.

Summary: In this study, bulk nanocrystalline Cu-Zr-Nb alloys were synthesized and annealed to investigate the reasons for maintaining nanosized grains. The results showed that the grain size remained in the nanoscale range due to solute atoms segregation along grain boundaries and Zenner pinning by intermetallic precipitates.

Summary: This study provides detailed insights into the atomic structures of heterogeneous interfaces in LSMO film grown on c-Al2O3 substrate, revealing the nucleation of periodic misfit dislocations and confirming theoretical predictions. Experimentally observed strain relaxation following misfit dislocation formation reduces residual strain, and interfacial interdiffusion within two monolayers at both interfaces was confirmed through electron energy-loss spectroscopy analysis.

Summary: In this study, we investigated the structural transformations and atomic rearrangements in strontium titanate (SrTiO3) induced by nanosecond pulsed laser irradiation. Our results show that the laser-irradiated surface of SrTiO3 transforms into an amorphous phase with a disordered crystalline region between the amorphous and ordered phases. We also observed the transformation of Ti+4 to Ti+3 due to oxygen vacancy formation caused by laser irradiation.
