When the precipitate is not yet coarsened as shorter in rupture life, the precipitation hardening effect may be intensified by the increasing of precipitate, so that the high temperature strength may be raised by the increase of W content, while the precipitate may coarsen markedly and the precipitation hardening effect may reduce on heating for sufficient long time.

The intermetallic compounds are coarsened into nubbly Cu6 Sn5 phase by adding excessive Cu into Sn-Cu solder alloy. For Sn-9Zn-xCu solder alloys, the long needle-like Zn rich phase which is the mainly existing form of Zn in Sn-Zn solders is transformed into Cu5 Zn8 phase and fine Zn rich phase by the addition of 2% Cu, while CuZn phase and Cu6 Sn5 phase are formed in Sn-9Zn-10Cu bulk alloy. When soldering within short time under 260℃, the ripening and growth of IMC at Sn-xCu/Cu interface are accelerated with increasing Cu content in Sn-Cu solders.

Firstly, the specific surface area of nano-coated particle is much larger than that of ordinary wollastonite, and the edges formed in comminuting is passivated, which made the slippy crystal surface coarsened. At the same time, the color of nano-coated particle became whiter, which fit for light ware. Secondly, if the coated wollastonite hasn't been modified by coupling agent, the toughness of PP/ wollastonite composite couldn't be improved.
