“…The manufacturing method directly determines the structure and properties of the produced materials. Methods such as powder metallurgy or mechanical alloying could contribute to obtaining materials, for example, with controlled grains sizes (TiTaZr gradient porosity materials) or refined grain structures to improve mechanical properties of alloys (NiCoMnIn magnetic shape memory alloys) [ 1 , 2 , 3 ]. It has been revealed that novel materials containing more than two alloying elements, such as ternary, quaternary, etc., alloys, also exhibit single-phase structures and better properties, i.e., mechanical properties, compared to conventional binary materials [ 4 ].…”

The presented work aimed to investigate the influence of the hafnium/(zirconium and molybdenum) ratio on the microstructure, microhardness and corrosion resistance of Ti20Ta20Nb20(ZrMo)20−xHfx (where x = 0, 5, 10, 15 and 20 at.%) high entropy alloys in an as-cast state produced from elemental powder and obtained via the vacuum arc melting technique. All studied alloys contained only biocompatible elements and were chosen based on the thermodynamical calculations of phase formation predictions after solidification. Thermodynamical calculations predicted the presence of multi-phase, body-centered cubic phases, which were confirmed using X-ray diffraction and scanning electron microscopy. Segregation of alloying elements was recorded using elemental distribution maps. A decrease in microhardness with an increase in hafnium content in the studied alloys was revealed (512–482 HV1). The electrochemical measurements showed that the studied alloys exhibited a high corrosion resistance in a simulated body fluid environment (breakdown potential 4.60–5.50 V vs. SCE).

“…Additionally, a minor fraction of pure Ni and Mn was identified in the as-milled powders. The Ni 45.5 Co 4.5 Mn 36.6 In 13.4 solid solution formation during MA as a function of milling time (2.5–70 h) was discussed in detail in [ 24 ]. The similar values of FWHM (full width half maximum) of (110) bcc peak and Ni and Mn peaks intensities indicate that prolonging milling time from 70 h to 100 h does not significantly influence the structure and phase composition of the received alloy.…”

The crystallization kinetics and structure evolution during annealing of the Ni45.5Co4.5Mn36.6In13.4 (at. %) powders produced by mechanical alloying (MA) was investigated. After 70 h and 100 h of MA, the powder consisted of a mixture of amorphous and nanocrystalline body-centered cubic (bcc) phases. We observed the relaxation in the as-received powder. The relaxation temperature (Tre) increases logarithmically with the annealing time. Annealing above 440 °C results in (1) ordering of L21, (2) dissolution of the residual Ni and Mn, (3) tetragonal MnNi phase formation and (4) γ phases precipitation. The activation energies of the B2 → L21 and Mn (α-Mn) → MnNi (P4/mmm) transformations were calculated.

“…before the casting process of composite material. The microstructures and grain structure of hybrid composite materials are not uniform and consistent [1]. The main reason for losing the mechanical properties of hybrid composite material is the mismatch densities of reinforcement particles which results in the non-uniform microstructure.…”

Chrome buffing dust and chrome-containing leather waste (CCLW) are produced from leather industries. In this study, extraction of chromium has been carried out from CCLW. Extracted collagen powder and alumina particles were ball-milled for 100 h. The average density of alumina content and ball-milled collagen was reduced from 3.725 g/cm 3 to 3.68 g/cm 3 . The mixture of collagen and alumina content was obtained in a single entity after ballmilling. Agglomeration of collagen powder was found when the mixture of alumina contents and without ballmilled collagen powder was encapsulated in the aluminum (Al) alloy. The microstructure of the ball-milled-reinforced composite had uniform dispersal of the reinforcements. After heat treatment, the grain structure of the aluminum/collagen/alumina composite material was refined. X-ray diffraction of ball-milled collagen powder and alumina-reinforced composite after heat treatment showed the presence of aluminum, alumina, chromium and chromic oxide phases. Comparative mechanical behavior study of aluminum/collagen powder, aluminum/alumina, Al/collagen powder/alumina with and without ball-milled and aluminum/collagen powder/alumina after heat treatment was performed to investigate the collagen and alumina addition effect in aluminum alloy.
