Porosity is a major concern in the production of light metal parts. This work aims to identify some of the mechanisms of microporosity formation in magnesium alloy AZ91. Microstructure analysis was performed on several samples obtained from gravity-poured ingots in graphite plate molds. Temperature data during cooling was acquired with type K thermocouples at 60 Hz at three locations of each ca...

AbstrakKomposit Matriks Logam (KML) merupakan salah satu material yang banyak digunakan di industri manufaktur terutama berbasis alumunium, karena logam ini mempunyai berat jenis rendah. Pada saat pembuatan KML bermatriks alumunium dengan penguat Al2O3 sudah dibuat dan industri. Proses Indonesia hal baru-baru ramai diminati, meskipun penelitian awal dilakukan jauh sebelumnya. Faktor penting pad...
