It is shown that melting and molding of aluminum bronze are difficult physical and chemical processes. In them the major role is played by the centers of crystallization of dendrites of a a-phase. the a-phase nanocrystals dissolved and the adsorbed oxygen and hydrogen. The role of the modifying crystals of an intermetallid of ZrAl3 is reduced to reduction of concentration of the disso... https://www.tamalpies.com/product-category/custom-arrow/
