The influence of alloying elements in aluminium on the grain refinement with ALTI5B1
aluminium casting solidification
2009/10/23
This work deals with the influence of alloying elements in aluminium on the grain refinement with various additions of AlTi5B1. Grain-refinement tests were made at a cooling rate of 15 °C/s. The resul...
Comparison of Sb and Sr on modification and refinement of Mg2Si phase in AZ61-0.7Si magnesium alloy
magnesium alloy AZ61-0.7Si alloy Mg2Si phase modification
2008/6/20
The effects of Sb and Sr on the modification and refinement of Mg2Si phase in an AZ61-0.7Si magnesium alloy were investigated and compared. The results indicate that the difference of Sb and Sr in the...
