Average crystallite size estimated by WH plot by fitting with a gaussian, lorentzian and pseudo voigt profile gives much different values ?

I estimated the average crystallite size of BiSn binary alloy using scherrers formula and since anisotropic microstrain is observed, I did Williamson hall analysis by fitting with a gaussian,...

The vickers hardness for Bi is almost double than that for tin. Should the hardness of the BiSn alloys therefore increase Bi concentration?

We had used the zone melting method for preparation of BiSn alloys having varying proportions of each component.
