Abstract

Penguatan tembaga murni dengan metode Equal Angular Channel Pressing telah dilakukan terhadap tembaga murni. Hasil pengerjaan ECAP dengan jalur ekstrusi ECAP rute Bc, dimana benda kerja diputar 90 ° setiap pass, menghasilkan pembelahan grain menjadi sub-grain yang memiliki ukuran yang menurun drastis dengan sudut butir yang lebih kecil.  Seiring dengan penurunan besar butir, kekerasan tembaga tersebut meningkat drastis. AbstractThe hardness of high purity copper has been increased through Equal Angular Channel Pressing method. The application of ECAP method with extrution rute Bc , in which the sample was rotated 90° for each pass, result in the generation of sub-grain within the grain. The size of new grain (sub –grain) is drastically smaller than initial grain and also has low angle. With the decreasing of grain size, the hardness drastically increases.
