Summary: Nickel-based hardfacing alloys are commonly used to prevent corrosion and wear in industrial applications. The properties of these alloys depend on the process parameters used in their preparation. In this study, the ERNiCr-B hardfacing alloy was deposited on AISI 304 stainless steel substrate using gas tungsten arc welding (GTAW) with optimized processing parameters. The results showed that the current had the most significant effect on the properties of the hardfaced deposit, including bead width, reinforcement height, hardness, and corrosion resistance.

Summary: This paper presents a systematic study on the effect of composition on microstructure, wear resistance, and corrosion resistance of iron-based hardfacings. It is found that alloy composition determines the constituent phases and extent of microstructural refinement during the hardfacing process. Addition of secondary carbide-forming elements like Nb and Mo improves both wear and corrosion resistance. The iron-based hardfacing with a composition of 36 Cr-4.3 Nb-1.5 Mo-0.3 N-4.1 C exhibits the best combination of hardness, wear, and corrosion resistance.

Summary: In order to improve the abrasion resistance of cast chromium-nickel steel, primary niobium carbides were produced in the metallurgical process by increasing the carbon content and adding Fe-Nb. The hardness of the samples after heat treatment ranged from 215 to 240 HV, which was higher than the reference cast GX10CrNi18-9 steel. The addition of 9.2 wt% Nb reduced the abrasive wear by almost 2.5 times compared to ordinary cast GX10CrNi18-9 steel.

Summary: This study investigated the quantitative precipitation process in stainless steels subjected to constant load at high temperature. The evolution of microstructure was evaluated and the presence of precipitates was analyzed using various techniques. The results showed that Cr23C6 precipitates were nucleated after a short period of time, and both Cr23C6 and sigma phase were found after a longer creep test. The volume of sigma phase increased with decreasing temperature, and the presence of precipitates led to an increase in microhardness.

Summary: This study provides detailed experimental characterization of a laser-clad metal matrix composite (MMC) consisting of hard tungsten carbide particles embedded in a comparatively soft nickel-based matrix. The relationship between the microstructure of the as-deposited reinforcing particles and their hardness is investigated. The dissolution of carbides caused by the high process temperature of laser metal deposition (LMD) is observed, leading to the formation of secondary phases at the matrix/particle interfaces and a gradual decrease in local hardness.

Summary: Dissimilar joints in the oil and gas industry, particularly between forged flanges and piping, are commonly used in subsea operations. In this study, the influence of post-weld heat treatment on the mechanical and microstructural behavior of a buttered dissimilar interface of AISI 4130 steel with nickel alloys was investigated. Gas metal arc welding processes with different filler metals were employed, and post-weld heat treatment was performed. The results showed that the welding process with pulsed current mode and Inconel 625 as filler metal exhibited lower dilution levels and better control of the partially diluted zones, making it more suitable for this type of application. However, it was also found that post-weld heat treatment made the interface more brittle regardless of the welding procedure.

Summary: The aim of this study was to analyze the crystallization kinetics of the Mg72Zn28 metallic glass alloy. The crystallization kinetics of Mg72Zn28 metallic glass were investigated using differential scanning calorimetry and X-ray diffraction. The phases formed during the crystallization process were identified as a-Mg and complex Mg12Zn13 phases. Activation energies for the glass transition temperature, crystallization onset, and peak were calculated based on the Kissinger model. The activation energies calculated from the Kissinger model were E-g = 176.91, E-x = 124.26, E-p1 = 117.49, and E-p2 = 114.48 kJ mol(-1), respectively.

Summary: In this study, a new filtering bioaerogel based on linear polyvinyl alcohol (PVA) and the cationic derivative of chitosan (HTCC) was developed for potential antiviral application. The introduction of linear PVA chains formed a strong intermolecular network architecture that efficiently interpenetrated the glutaraldehyde-crosslinked HTCC chains. The modified aerogels showed enhanced micro- and mesopore space as well as BET-specific surface area compared to the starting sample chitosan aerogel crosslinked by glutaraldehyde (Chit/GA). XPS analysis confirmed the presence of cationic groups on the aerogel surface, which can interact with viral capsid proteins. The HTCC/GA/PVA aerogel demonstrated efficient trapping of mouse hepatitis virus (MHV) from suspension without cytotoxic effects on fibroblast cells.

Summary: CuZr-based bulk metallic glass matrix composites have unique mechanical properties compared to bulk glassy samples. The cooling rate during solidification determines whether a bulk metallic glass or a bulk metallic glass matrix composite can be formed. For the Cu45Zr48Al7 alloy, a minimum cooling rate lower than 40 K/s is required to allow partial crystallization of the B2 phase and observe the strain hardening effect.

Summary: To visualize the tetragonal distortions in high carbon martensitic steels, two different techniques, RA and PM, were used to analyze BKD patterns. RA distinguishes between hypothetical phases of different fixed c/a, while PM determines a best fitting continuous c/a by projective transformation of a master pattern. The application of RA and PM on martensitic microstructure delivered similar qualitative maps of c/a, with RA being faster and more precise for initial surveys and PM providing higher precision results.
