Sonnet 2: By William Shakespeare
Read by: Bertram Selwyn (Bernard Shakespeare) "When forty winters shall besiege thy brow, And dig deep trenches in thy beauty's field, Thy youth's proud livery, so gazed on now, Will be a tatter'd weed, of small worth held: Then being ask'd where all thy beauty lies, Where all the treasure of thy lusty days, To say, within thine own deep-sunken eyes, Were an all-eating shame and thriftless praise. How much more praise deserved thy beauty's use, If thou couldst answer 'This fair child of mine Sha

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.
