To clarify this issue, deposition was made with targets of Cr, Al and C alone, without the involvement of V.
Cr and C targets were mounted on the DC power and the Al was mounted on the RF power.
More detailed investigation is required to further clarify the atomic movements in the gas transport process in the Cr-Al-C, or in the Cr-V-Al-C cases.
Evaporation of Al in MAX phases during sputtering was reported to occur at 973 K [8, 9] , or higher [10].

Fig.1 obtained from Pb-B shielding alloys reveals that the microstructure of Pb-B alloys consists of Pb matrix, Al phase in the form of both fine needle-like phase and some relatively coarse Al-rich phase dispersed in the Pb matrix.
One can find from Fig.1 that the shape of Pb matrix gradually degenerate from skeleton to lath, and the sizes of coarse Al-rich and needle-like Al phases increase up to 1-2μm firstly, then decrease down to less than 0.5μm with increasing B content.
In contrast, there is clear difference in volume fraction that Al phase increase while Pb matrix decrease.
Hence, it is feasible to suggest that B plays an important role to control the growth of Pb matrix and Al phase due to the appearance of a large number of ultrafine needle-like Al phases.
