Abstract
In this paper, the production of Al2O3-Mo nano-composites via mechanical milling was investigated. Molybdenum and alumina powders with certain ratios were grounded in a planetary ball mill at different times. XRD technique was used to determine the crystallite size of the milled powders. The microstructure of milled powders was studied using optical and electron microscopes. The crystallite sizes of milled powders were in nano-meter scale and increasing the milling time led to decreasing of crystallite size. Microstructural investigations showed uniform distribution of ultrafine second phase in matrix.
