Al-90 wt% Cu (bronze)
This is a copper-aluminium bronze containing 10 wt% aluminium. A small amount of iron is often added to act as a grain refiner to improve the mechanical properties. Alloys with more than 8 wt% aluminium solidify as the β phase. Below about 930°C, Widmanstätten α phase precipitates. At the eutectoid temperature (565°C) the remaining β decomposes to a lamellar eutectoid of α and β. Rapid cooling from the high temperature β phase can form martensite instead of Widmanstätten α.

From the Heart
This video segment describes how the chambers of the heart contract and relax in synchrony to push blood through the pulmonary and systemic loops of the circulatory system. You'll see how the heart pumps oxygen-depleted blood to the lungs, where red blood cells acquire oxygen before travelling back to the heart and then on to the rest of the body. The video is nice illustration of how the circulatory and respiratory systems work together to carry in oxygen and remove waste.  Closed captioning i
