THE EFFECT OF VARIATIONS MECHANICAL MILLING TIME AND SINTERING TEMPERATURE ON MICROSTRUCTURE CHARACTERIZATION OF MMC Mg-Al-TiO2

Author :
Pratomo, Yogar Adi ( 2705100002 )




ABSTRAK

The necessary with the ability of structural components light and strong experience a significant improvement. This has encouraged the development of new materials based Metal Matrix Composites MMCs. Composite Mg-Al-TiO2 with Mg as the matrix and the Al-TiO2 produced Al3Ti as reinforced already developed. This research is based on the reaction 3TiO2 13Al 8594 3Al3Ti 2Al2O3. Powder mixed with the milling methods on speed 800 rpm. Variations using mechanical milling time within 24 hours 48 and 60 hours. The process of using assessment compaction 500 MPa. The process of sintering temperature variations using the 800 900 1000 oC. Material characterization specimens using MO XRD SEM EDS and DTATGA. Intermetallic Al3Ti compound in temperatures ranging form 800 OC with the long mechanical grinding to 48 hours with the highest peak at 2952 39.54. The length of time the structure of the mechanical grinding MMC akan increasingly homogeneous. From this research note that the MMC specimens Mg-Al-TiO2 with the long mill 48 hours and sintering temperature 900 OC intermetallic Al3Ti compound produced the most optimal.
