A typical eutectic microstructure of both unmodified and Sr-modified (200 ppm) Al–10 wt.% Si–0.1 wt.% Fe alloy is shown in Fig. 1 for two different magnifications. The unmodified alloy in Fig. 1a and b reveals primary Al dendrites (bright in Fig. 1a) and a eutectic Si phase that appears as needles just in two dimensions but as coarse interconnected plates if viewed in three dimensions.

Purpose: Dual-energy X-ray absorptiometry (DXA) is the gold standard technique to measure areal bone mineral density (aBMD) for the diagnosis of osteoporosis. Because DXA relies on the attenuation of photon to estimate aBMD, deposition of bone-seeking metallic elements such as strontium, lead, and aluminum that differ in atomic numbers from calcium can cause inaccurate estimation of aBMD.
