Four composites, MoSi2+ZrO2, MoSi2+ZrO2(Y2O3), MoSi2+ZrO2+SiC and MoSi2+ZrO2(Y2O3) +SiC are fabricated by mechanical alloying. It is clear that cracks produced
Two kinds of Al-Zn-Mg based alloys with and without Sc, Zr addition were prepared by ingot metallurgy.The tensile mechanical properties and microstructures of t
A needle coke was graphitized at different heat treatment temperature (2000℃ to 3000℃). The electrochemical intercalation mechanism of Li into the graphitized
