Increased milling time seems to limit the grain growth of the NiMo matrix by producing well-dispersed Mo2C particles during sintering. The amount of grain boundaries greatly increases the Hall–Petch strengthening, resulting in significantly higher strength in the case of 48-h-milled NiMo-SiC DPS alloys compared with the 8-h-milled alloys.

The effect of milling time on the morphology, microstructure, physical and mechanical properties of pure Al-5 wt % Al2O3 (Al-5Al2O3) has been investigated. Al-5Al2O3 nanocomposites were fabricated using ball milling in a powder metallurgy route. The increase in the milling time resulted in the homogenous dispersion of 5 wt % Al2O3 nanoparticles, the reduction of particle

Effect Of Milling Time On Matterials. Sand casting is able to make use of almost any alloy.An advantage of sand casting is the ability to cast materials with high melting temperatures, including steel, nickel, and titanium.The four most common materials that are used in sand casting are shown below, along with their melting temperatures.

Dec 01, 2012· Fig. 2 shows the morphologies of milled mixture powders under different ball-milling times. It can be seen that more mixture powders became flattened as the ball-milling time increased from 2 to 8 h, which was caused by the shearing effect of the balls.The largest surface areas were achieved in the 8 h ball-milled mixture powders, and the thickness of

The increase in the milling time resulted in the homogenous dispersion of 5 wt % Al2O3nanoparticles, the reduction of particle clustering, and the reduction of distances between the composite particles. The significant grain refining during milling was revealed which showed as a reduction of particle size resulting from longer milling time.
