<http://eprints.untirta.ac.id/id/eprint/52152> <http://purl.org/ontology/bibo/abstract> "Magnesium merupakan salah satu material yang dapat digunakan sebagai\r\nimplan bagi tubuh karena tubuh manusia memerlukan magnesium sebanyak 240-\r\n420 mg/hari. Selain itu magnesium memiliki modulus elastisitas (41 ˗ 45 GPa) dan\r\ndensitas (1,74 g/cm3\r\n) yang mendekati tulang manusia. Namun magnesium\r\nmemiliki laju korosi yang tinggi sebesar 2,89 mmpy (dalam larutan NaCl 0,9%).\r\nOleh karena itu, dilakukan proses Accumulative Roll Bonding (ARB) untuk\r\nmengendalikan laju korosinya. ARB merupakan salah satu metode severe plastic\r\ndeformation (SPD) dengan cara memberikan regangan besar ke dalam material\r\ntanpa mengubah bentuk geometrisnya selama siklus penumpukan, pemasanan dan\r\npengerolan material. Magnesium dipanaskan (annealing) pada temperatur\r\n250°C dan 350°C dengan waktu tahan 25 menit, kemudian dilakukan proses\r\nARB dengan variasi 1,2,3, dan 4 siklus. Komposisi diuji menggunakan SEMEDS, menunjukan kadar pelat pure Magnesium as annealed sebesar 99,77%.\r\nUkuran butir diamati menggunakan mikroskop optik dan diukur dengan\r\nsoftware ImageJ, menghasilkan ukuran butir rata-rata terkecil sebesar 7,204 ±\r\n1,185 µm. Pengujian imersi dan elektrokimia dilakukan untuk mengetahui laju\r\nkorosi pelat magnesium dan mendapatkan laju korosi terendah sebesar 0,0012\r\nmmpy."^^<http://www.w3.org/2001/XMLSchema#string> .
