| dc.description.abstract | Penelitian ini bertujuan untuk mengetahui pengaruh penambahan Cr dan
Cu terhadap kekuatan lelah siklus rendah (low cycle fatigue/LCF) besi cor
kelabu. Besi cor kelabu FC 20 dan tiga besi cor kelabu FC20 yang
ditambah Cr (0,23%, 0,32% & 0,47% wt) dan Cu (0,67%-0,7%) diuji lelah
pada mesin servo pulser MTS810. Dimensi spesimen uji dibuat dengan
mesin CNC sesuai dengan standarASTM E466. Hasil pengujian
menunjukkan bahwa terdapat peningkatan kekuatan lelah yang signifikan.
Analisis data menggunakan metode Downing (1983) dan Fash (1982)
menghasilkan strength coefficient (A) antara 2,336 – 2,896 dan fatigue
strength exponent antara –0,251s/d –0,266 | en_US |
