It is well-known that strontium addition into molten metal as a eutectic modifier increases the elongation and toughness values of cast parts by refining phases. However, when over-modification occurs, porosity due to some unwanted physical chemical reactions develop within structure. On other hand, it has been seen high cooling rates tend reduce alloy, decrease grain size secondary dendrite ar...

Abstract Obtaining a strong bond between aluminum and steel is challenging due to poor wettability melt brittle intermetallic phases forming in the interface. In this research, novel coating method, namely hot dipping of Sn, has been developed treat insert surfaces. Results show that without preheating mold or Sn-coated insert, thin, crack-free, continuous metallurgical bonding layer was achiev...
