Master alloy that constitutes the inoculant, preferably for zinc alloys and the hypereutectic lanthanum-modified Zn-Al-Cu alloy

摘要

the object of the application is run, which is characterized by the fact that contains 9 - 11% by weight and the rest is la, al and improves the mechanical property and utility modified alloys by changing the microstructure and crystallization temperature.the declaration also includes obtaining alloy zn - al - cu modified la and is that is inserted in the base alloy sufficient mortar alla resulting in an alloy containing 8 - 11% al by weight, 0.5 - 3% cu, 0.1 to 1% by weight and the rest is la, zn.the resulting alloy has a stable two-phase microstructure of elevated mechanical properties and performance, and increased corrosion resistance.
