STUDI PERUBAHAN STRUKTUR KRISTAL MATERIAL HASIL PERLAKUAN EQUAL
CHANNEL ANGULAR PRESSING RUTE Bc DENGAN VARIASI JUMLAH PASS: STUDI KASUS
SAMPELALUMINIUM PADUAN 5052. Proses Equal-Channel Angular Pressing (ECAP) merupakan salah
satu metode yang digunakan untuk memodifikasi ukuran butir pada logam pejal. Studi ini menganalisis pengaruh
jumlah pass pada logam hasil perlakuan ECAP rute Bc, yang dititikberatkan pada perubahan struktur kristal
yang terjadi. Studi ini bertujuan untuk mengetahui struktur kristal yang diinginkan, dengan diprediksi berdasarkan
jumlah pass yang ditentukan. Untuk memudahkan studi ini, digunakan data sekunder hasil uji X-Ray
Diffractometer (XRD) pada sampel aluminium yang diberi perlakuan ECAP rute Bc dengan variasi jumlah pass
yang berbeda. Ada empat sampel yang digunakan. Satu sampel tidak diberikan perlakuan ECAP sebagai sampel
pembanding, tiga sampel lainnya diberikan perlakuan ECAP rute Bc dengan variasi jumlah pass 2, 4, dan 8.
Analisis kualitatif dan kuantitatif hasil uji XRD dilakukan menggunakan perangkat lunak Rigaku PDXL. Hasil
analisis menunjukkan bahwa perlakuan ECAP rute Bc pada sampel uji menyebabkan perubahan struktur
kristal, regangan kisi, dan ukuran kristalit pada sampel uji. Perlakuan ECAP rute Bc dengan jumlah pass yang
tepat dapat menyeragamkan struktur kristal menjadi lebih homogen dan rapi. Struktur kristal yang diinginkan
dapat diprediksi berdasarkan jumlah pass yang ditentukan. Namun, regangan kisi dan ukuran kristalit tidak
dapat diprediksi berdasarkan jumlah pass yang ditentukan.
