Besides, so-called bulk metallic glasses often devitrify with a very high nucleation rate, yielding a dispersion of nanocrystals in the amorphous matrix at the first crystallization stage [100-102]. It means that precipitation develops in nanometric volumes, which can be realized in nanometric spherical regions (of radius R) around nucleation sites. One should expect a similar hysteresis behavior in bulk metallic glasses as a result of the depletion and size effects shown in the present paper. The corresponding analysis will be made elsewhere. 

As already remarked in Sect. 4.5.1 (Introduction), LA was primarily designed as a technique for direct sampling in the bulk analysis of solid samples. The main advantages of LA are the possibility of ablating all types of solid material (metals, isolators, glasses, crystals, minerals ceramics, etc.), no special requirements on the...
