“…One of the most effective and well-established methods to obtain the metal matrix composite powders is the mechanical milling process [38]. Indeed, this process has been widely exploited for the preparation of MCrAlY-based micro and nanocomposite powders [104]. Typically, the mechanical milling process starts with a powder charge comprised of a blend of a matrix and one or more of the reinforcement materials together with the grinding media.…”

The application of metal-matrix composite coatings for protecting and improving the service life of sliding components has demonstrated to have the potential of meeting the requirements of a diverse range of engineering industries. Recently, a significant body of research has been devoted to studying the mechanical and tribological performance of dispersion-strengthened MCrAlY coatings. These coatings belong to a class of emerging wear-resistant materials, offering improved properties and being considered as promising candidates for the protection of engineering structural materials exposed to tribological damage, especially at elevated temperature regimes. This paper attempts to comprehensively review the different reinforcements used in the processing of MCrAlY-based alloys and how they influence the mechanical and tribological properties of the corresponding coatings. Furthermore, the major fabrication techniques together with their benefits and challenges are also reviewed. Discussion on the failure mechanisms of these coatings as well as the main determining factors are also included. In addition, a comprehensive survey of studies and investigations in recent times are summarized and elaborated to further substantiate the review.

“…Further, mechanical milling can be done in wet as well as dry modes. Wet ball milling procedure adopts antifriction bearing system which leads to 30% lesser power consumption and finer grain size [14,15]. Keeping in view these beneficial factors, the wet ball milling technique has been employed presently to achieve reduction in particle size and uniform blend of particles in nano phase.…”

The alloys with composition:Pb60Sn20CdxZn20-x, where x=0, 5, 10, 15 and 20 mol.% were fabricated at nano-scale as well as bulk scale using the convention melt quench technique. Different characterizations techniques such as Transmission Electron Microscopy (TEM), Field Emission-Scanning Electron Microscopy (FE-SEM) and Energy Dispersive Spectroscopy (EDS) analysis were performed to verify the particle size reduction to nano-scale, surface morphology and elemental composition of Pb60Sn20ZnxCd(20-x) alloy systems. These nano-structured and bulk alloy systems were experimentally investigated and compared for their potential use in the radiation shielding applications. Further, radiation shielding effectiveness against electron beam, proton beam, alpha and heavy carbon ion beams has also been investigated for fabricated bulk alloys using Geant4 simulations. Present theoretical and experimental analysis affirmed that the radiation shielding efficacy gets enhanced for ball-milled PbSnCdZn nano alloy specimens as compared to bulk counterparts.
