| Abstract Scope |
In the present investigation, nanocrystalline (NC) materials, such as pure Al and Mg-doped Al were manufactured using cryo-milling followed by the spark plasma sintering process. The changes in crystallite size were determined using X-ray diffraction. Hardness measurements were performed using a Vickers micro-hardness tester. The friction and wear performance of NC materials were studied using a tribometer. Results showed that the crystallite size decreased with increasing cryo-milling time. The decrease in crystallite size increased the hardness of NC materials. The increase in hardness resulted in a decrease in the coefficient of friction and wear rate. The Mg-doped Al material showed superior hardness, friction, and wear performance compared to pure Al. The underlying mechanisms for the reduction in crystallite size and its effect on hardness, friction, and wear performance will be discussed. |
