“…In specific, the Ta/N [94], Ti/N [95][96][97][98], Nb/N [98,99], and Zr/N [8] systems have been studies. However, the technique has also be used to study carbides, including the Ti/C [100], Zr/C [100], W/C [101], Nb/C [102], along with other systems, including Mo/ Si [103][104][105][106], W/Si [107,108], Ni/Al [109], and Ni/Ti [109]. Figure 4 shows the values of the activation energies obtained by this method in gas-solid systems.…”
