Abstract
The holy Quran, from more than 1400 years, told us that Zul-karnain had made a metallic composite material between iron and copper [1,2] as follows:
“Bring me sheets of iron” — until, when he had leveled [them] between the two mountain walls, he said, “Blow [with bellows],” until when he had made it [like] fire, he said, “Bring me, that I may pour over it molten copper * So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration.”: Translation of verses 96 and 97 in Surah Al-Kahf (18), The holy Quran [3].
According to the above story, the matrix is copper, while reinforcement is iron of this metal matrix composite. The present paper is going to investigate the Metal-Matrix Composite Material (MMC) suggested by Zul-karnain at different manufacturing conditions by using the experimental method. The effect of reinforcement temperature on the integrity of such MMC is one of the main goals of the present work. The mechanical behavior of the present QMMC is also examined in the present research as preliminary study. Furthermore, the finite element method is used to predicate the debonding force of MMC based on Virtual-Crack-Closing-Technique (VCCT).
