“…Accordingly, the Li species in the Ni/Fe 2+ cathode materials at various cutoff potentials was recognized in the ex situ XRD spectra. It is interesting that the detected Li species in these samples was elemental Li, [32][33][34][35][36] as it allowed us to peruse the electrochemical mechanism of the Ni/Fe 2+ PBA in the Li-ion storage process. When Li + ions from the electrolyte were inserted into the interlayers of Ni/Fe 2+ , they could be reduced in situ by the incoming electrons instead of forming compounds with the host material.…”

“…The hardness curve confirms that increased hardness occurred due to high aluminium content from the alloy micrographs. The high content initiates formation of large quantity of -precipitates and interactions of lattice strain fields between the -precipitates themselves [13,40].…”

“…It is also possible because of effective grain strengthening effect for the formed -phase owing to the crystallography matching relationship. The applied crystallography matching relationship is identified using the edge-to-edge matching model in different phases of Mg-Li alloys and composites [27,[40][41][42][43]. Al-3Ti-1C and Al-5Ti-1B master alloys are considered strong grain refiners for alloys with full BCC structure and HCP structures, respectively.…”

Mg-Li based alloys are widely applied in various engineering applications. The strength of these alloys is modified and enhanced by different strengthening mechanisms. The strengthening mechanisms of these alloys and their composites have been extensively studied during the past decades. Important mechanisms applied to strengthening the alloys include precipitation strengthening, solution strengthening, grain and subgrain strengthening, and dislocation density strengthening. Precipitation and solution strengthening mechanisms are strongly dependent on composition of the alloys and thermal treatment processes, whereas grain and subgrain and dislocation density strengthening mechanisms majorly depend on thermomechanical processing. In this paper, recent studies on conventional processes for the strengthening of Mg-Li based alloys are summarized as they are critical during the alloys design and processing. Main strengthening mechanisms are objectively reviewed, focusing on their advantages and drawbacks. These can contribute to enhancing, initiating, and improving future researches for alloys design and suitable processing selection.

“…EDS results of analysed intermetallic compounds revealed a high concentration of Al, Sr and Mg though Mg may come from the matrix. The observed intermetallic compounds have most probably resulted from the grain refinements addition in the form of Mg 17 Sr 2 , Mg 2 Sr or Al 4 Sr phase as suggested in [23][24][25], however, it must be noted that melting temperatures of proposed phases are 606°C, 680°C and 1040°C, respectively. Moreover, according to the Mg-Sr binary system [22] and suggestions in [23], the Mg 2 Sr phase is observed Mg alloys with a higher concentration of Sr (more than 1.5%).…”

The paper presents the results of the influence of commercial TiBor and AlSr10 master alloys on the refine the grains size, hardness and crystallisation process based on the thermal-derivation analysis of light cast magnesium-lithium-aluminium alloys. The effects of TiBor and AlSr10 content on the characteristic parameters of the crystallisation process of Mg-Li-Al alloys were investigated by thermal-derivative analysis (TDA). Microstructural evaluations were identified by light microscope, X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray spectroscopy.The results showed that the addition of TiBor master alloy reduced the grain size of Mg-9Li-1.5Al cast alloy from 900 μm to 500 μm, while the addition of AlSr10 master alloy reduced the grain size of investigated cast alloy from 900 μm to 480 μm. Moreover, an addition of TiBor and AlSr10 simultaneously reduced the grain size from 900 μm to 430 μm.Results from the thermal-derivative analysis showed that the addition of grain refinement causes a decrease in nucleation temperature and solidus temperature.
