“…It has been reported that T M of Pb increases in the confinement of the Al matrix and this increase is particle size dependent [7]. The melting of Pb nanoparticles was studied by means of dynamic mechanical analyzer / internal friction measurements [8] and transmission electron microscopy (TEM) [6]. Structural, thermodynamic and diffusion properties of crystalline particles completely embedded in a metallic matrix have been investigated in detail in a variety of homogenous systems of immiscible elements for the past two decades.…”

Al-Pb binary system is a suitable model system for testing liquid phase dispersion strengthening in bulk materials for structural applications. Liquid Pb islands can be finely dispersed in still solid Al matrix due to the substantial difference of melting points. The Al-Pb system prepared by means of Equal Channel Angular Pressing (ECAP) process was investigated by Small-Angle Neutron Scattering technique (SANS) which enables in-situ measurement of size and morphology parameters of Pb inclusions at elevated temperatures. It was observed that the lead particles were elongated roughly in the direction of ECAP. During the subsequent in-situ thermal cycle RT-400°C-RT, the elongated Pb particles transformed to nearly spherical shape. The change of scattering contrast during melting of Pb mapped the transform of the confined lead particles to the liquid phase. The center of the transition region is around 342°C (615K) for both the as-cast and the ECAP deformed samples, which is a significant shift with respect to the free Pb melting point 327°C (600K). For the ECAP sample, the transition is not sharp, indicating a broad size distribution of lead particles.
