    A state-of-the-art review on mechanical characteristics of different fiber metal laminates for aerospace and structural applications
    (Springer London Ltd, 2022) El Etri, Hamza; Korkmaz, Mehmet Erdi; Gupta, Munish Kumar; Gunay, Mustafa; Xu, Jinyang
    The reduction of weight elements is considered as a major objective of several manufacturing companies. This objective will help in growing application sections of the used fiber composites for important structural elements. Modern fiber metal laminate (FML) having lightweight properties is established to be used instead of other substances in different applications including those related to the aerospace industrial sector. Fiber metal laminate is being deemed as an alternative significant substance that is being extensively explored due to its operation, unlike other current materials. There are different profitable FML such as GLARE (glass-reinforced aluminum laminate), established on elevated intensity ARALL glass fibers (aramid-reinforced aluminum laminate), built on fibers of aramid, in addition to CARALL (carbon-reinforced aluminum laminate), centered on fibers of carbon. This paper analyzes important information that contributes to the mechanical characteristics of FMLs under tensile, flexure, impact, etc. conditions.

    TRIBOLOGICAL AND SURFACE MORPHOLOGICAL CHARACTERISTICS OF TITANIUM ALLOY AGAINST COATED CARBIDE PIN
    (2022-08) El Etri, Hamza
    Considering the wide awareness regarding titanium alloys, this research emphasizes the Ti–6Al–4V titanium alloy tribological performance against WC cemented carbide balls at numerous cooling conditions. The tribological tests were performed on Ti–6Al–4V flat specimens utilizing a ball-on-flat tribometer at dry, hybrid graphene/boron nitride mixture nanoparticles-MQL (nano-3), in addition to nanographene with MQL (nano-1) and boron nitride with MQL (nano-2) circumstances. Test parameters include a sliding distance of 100 m, sliding velocities equal to 50 mm/s and 75 mm/s, on the other hand, the loads were 10 and 20 N. Afterward, the maximum serious tribological properties like volume loss, friction forces, wear depth, along with SEM micrographs were examined. The consequences have shown that the smallest value of volume loss took place in the nano-3 circumstance. Moreover, the greatest value of wear depth was found to be equal to 105 ?m under the dry environment at 75 mm/s sliding speed and 20 N load. In addition, the minimum friction force value (2.3 N) was accomplished at a sliding speed of 50 mm/s and load of 10 N under the nano-3 circumstance.

    Tribological and surface morphological characteristics of titanium alloys: a review
    (Springernature, 2022) Gupta, Munish Kumar; El Etri, Hamza; Korkmaz, Mehmet Erdi; Ross, Nimel Sworna; Krolczyk, Grzegorz M.; Gawlik, Jozef; Yasar, Nafiz
    Being easily fabricated, welded, biocompatible, having a high strength-to-weight ratio, withstanding comparatively high temperatures up to 800 degrees C and low modulus of elasticity make grade titanium and its alloys an important choice for automotive, biomedical and aerospace industries. In contempt of the different pleasant assets of Ti-6Al-4V alloy, the operation of this alloy is restricted especially when it comes to tribological and surface morphological characteristics. Enhancing these properties is important, for this purpose, a diversity of attempts and studies have been conducted. This paper mounts a review of morphological and tribological behaviors of titanium alloys including Ti-6Al-4V against different materials counting with carbide tools and other types of materials under dry and lubricated sliding conditions. The surface morphological, wear, and other properties have been discussed in this review article.
