Ibrahim; Astawa, I Nyoman Gede Putrayasa; Mabruri, Efendi, 2018, "Studi Perubahan Struktur Kristal Material Hasil Perlakuan Equal Channel Angular Pressing Rute Bc dengan Variasi Jumlah Pass: Studi Kasus Sampel Aluminium Paduan 5052", https://hdl.handle.net/20.500.12690/RIN/656FDD, RIN Dataverse, V2
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... |
Mabruri, Efendi; Morinaga, Masahiko; Koyama, Toshiyuki; Sakurai, Shingo; Murata, Yoshinori, 2018, "Diffusion of Re and Ru in the γ′ Phase of Ni based Alloys", https://hdl.handle.net/20.500.12690/RIN/RMQE9D, RIN Dataverse, V2
The diffusion of Re and Ru in the γ`-Ni3Al phase has been investigated at a range of temperatures 1423-1523 K by using the pseudo-binary diffusion couples. It was found that the concentration gradient of Re appeared to promote the uphill diffusion of Al, whereas that of Ru did no... |
Mabruri, Efendi; Morinaga, Masahiko; Murata, Yoshinori; Hattori, Masataka; Kunieda, Tomonori; Hasuike, Kouichi, 2018, "Al and Re Interdiffusion in the γ-Phase of Ni-Al-Re System", https://hdl.handle.net/20.500.12690/RIN/BHT3AN, RIN Dataverse, V2
The activation enthalpies and frequency factors for interdiffussion of Al and Re in the γ-phase of Ni-Al-Re ternary system were estimated by a series of experiments using diffusion couples in the temperature range from 1200 to 1300°C. The method developed by Whittle and Green was... |
