Modyfikacja brązu cynowego CuSn10

Investigations on the modification of tin bronze CuSn10 with Zr additive as well as the complex additives consisting of P-Fe-Zr and Mg-P-Fe-Zr revealed the advantageous influence of these reagents on a structure and properties of the alloy. The modification processes caused the apparent grain refinement and as the consequence the increase of tension strenght of about 20% was achieved. Electron microscopy examinations allowed to identificate heterogeneous crystallization nuclea and to determinate the elements which formed the nuclea.
