the research aims to develop a novel and safer milling route to produce Hard Metals. Considering the risks associated with milling fine particles under organic solvents, especially the increased fire and explosion risks, we propose milling under aqueous milling media to diminish the risks associated with fire hazards, while maintaining the oxidation level at a minimum. the samples were sintered in an industrial sintering oven under vacuum at 1380°C subsequent to milling and drying. the characterisation of the materials has been done by X-ray diffraction, scanning electron microscopy, particle size analysis, optical microscopy, and a mag-netometer. the obtained results indicate that appropriate properties of the powders after milling and drying as well as the desired biphasic (Co-WC) phases were obtained after sintering, thus proving the feasibility of such a route and diminishing specific fire hazards.

Magnetic microstructure in the as suction cast Fe 69 B 20 Nb 2 Hf 2 Si 2 Y 5 alloy was revealed by combined Lorentz-TEM and LM-STEM DPC analysis. The thin foil of the alloy was found to be composed primarily of the amorphous phase with few dendritic structures. Magnetic domains were found large in the µm range with an average domain wall width of 52 nm. The magnetic domain boundaries are easily mobile, what was confirmed by in situ applied magnetic field. The LM-STEM DPC complements the Lorentz-TEM analysis by providing details on the intensity and spatial distribution of the magnetization vector within the domains.

To fabricate a lead-free solder with better properties, a surface-modified precipitate calcium carbonate (PCC) was added as a reinforcement phase to tin-zinc (sn-9Zn) solder. The surface modification of PCC was done by using electroless plating to deposit nickel (ni) layer on the PCC. Based on microstructure analysis, a thin layer of ni was detected on the reinforcement particle, indicating the ni-coated PCC was successfully formed. next, composite solder of sn-9Zn-xni-coated PCC (x = 0, 0.25, 0.50, 1.00 wt.%) was prepared. The morphology and phase changes of the composite solder were evaluated by using optical microscope and X-ray diffraction (Xrd). significant refinement on the grain size of Zn was seen with the additions of ni-coated PCC, with a new phase of ni 3 sn 4 was detected along with the phases of sn and Zn. The wettability of sn-9Zn was also improved with the presence of ni-coated PCC, where the wetting angle decreased from 28.3° to 19.4-23.2°. Brinell hardness test revealed up to 27.9% increase in hardness for the composite solder than the pristine sn-9Zn solder. This phenomenon contributed by the increased in dislocation resistance through Zener pinning effect and Zn grain refinement within the composite solder which enhanced the overall properties of the composite solder.

Carbon steel is one of the most widely used alloys in many industries, however, its use is limited by its low corrosion resistance. Depositing a layer of phosphate on its surface improves the corrosion resistance as well as other properties, such as wear resistance, adhesion etc. accordingly, preliminary studies demonstrated that carbon steel coated with phosphate layers can be used in the manufacture of carabiners for various fields: civil engineering, oil industry etc. Whereas, to demonstrate their capacity to operate in severe conditions related to fire rescue and extinguishing operations, it is necessary to evaluate the thermal behaviour of these materials. Thus, the main goal of this paper is to study the behaviour at high temperatures of three different types of phosphate layers deposited on carbon steel surface, by sTa analysis. also, the paper aims to study the formation of different phosphate layers by determining the types of compounds formed after the completion of the phosphating process, by XrD analysis.
