Surfactant-decorated graphite nanoplatelets(GNPs) reinforced aluminum nanocomposites: sintering effects on hardness and wearZeeshan Baig1,Othman Mamat1,Mazli Mustapha1,Asad Mumtaz2,Sadaqat... nanocomposite sample. Noticeably, EC-based 0.5 wt% GNPs/Al samples showed the highest increment of 31% increase in hardness with reduced wear rate of 98.25% at 620°C, while a 22% increase in hardness......
Effects of high pressure on the microstructure and hardness of a Cu-Zn alloyZHAO Jun a, LIU Lin b, YANG Jingru c, PENG Guirong a, LIU Jianhua a, ZHANG Ruijun a, and XING Guangzhong a a State Key... diffraction (XRD), and the hardness of the Cu-Zn alloy was also measured. The results show that the α phase with a smaller grain size, different shapes, and random distribution appears in the Cu-Zn alloy......
The combined influence of grain size distribution and dislocation density on hardness of interstitial free steelWei Li1,2,Martina Vittorietti3,2,Geurt Jongbloed3,Jilt Sietsma11. Department... distribution. The dislocation density is determined through XRD measurements. The hardness is analyzed on its relation with the mean grain size, as well as with the grain size distribution......
