dc.description.abstractPenelitian untuk mengembangkan fabrikasi aluminum berpori dengan teknik metalurgi serbuk dengan space holder paduan Pb-Sn telah dilakukan. Serbuk aluminum berbentuk flake dicampur dengan tiga variasi fraksi massa paduan Pb-Sn sebagai space holder. Campuran tersebut kemudian dikompaksi dengan tekanan 300 kg/cm2 sehingga membentuk green body. Spesimen diperoleh setelah sintrering dua tahap dilakukan atas green body yaitu sintering suhu rendah (200oC), dan dilanjutkan dengan sintering pada suhu (550oC). Spesimen diuji struktur mikro dengan mikroskop optik dan ditentukan porositasnya dengan penimbangan dan pengukuran dimensinya. Sedangkan kekuatan tarik dan modulus elastisitas diperoleh dari uji tekan menggunakan universal testing machine. Hasil penelitian menunjukkan bahwa aluminum berpori dapat diproduksi, dengan porositas mencapai 31,2% pada fraksi massa space holder sebesar 0.34. Kurva tegangan-regangan yang dihasilkan dari pengujian kuat tekan berbentuk plateau dan menunjukkan bahwa nilai kekuatan menurun seiring dengan peningkatan porositas material.en_US
