Abstract

In this work, B₄C, B₄C + 5 at.% Al, B₄C + B, and B₄C + B + 5 at.% Al were arc melted, and the resultant solid products were characterized. Results from x-ray diffraction and scanning electron microscopy showed that adding Al alone in B₄C did not result in Al doping; adding Al and B in B₄C led to Al doping. Al-doping also changed the surface energy of boron carbide in the liquid state, thus altered the wettability. Transmission electron microscopy revealed that stacking faults are more likely to form in the Al-doped sample, especially in the regions where the Al concentration is high.
