Deformation behavior of spray-formed hypereutectic Al–Si alloys

Modification of Eutectic Si in Al-Si-(Ba) Alloy by Inducing a Novel 9R Structure in Twins

“…It has been confirmed that the refinement and passivation of eutectic Si is an effective way to improve the mechanical properties of Al-Si alloys [ 10 , 11 , 12 ]. The normal methods to modify eutectic Si are as follows: adding modifying elements [ 10 ], rapid solidification [ 13 , 14 ], mechanical or electromagnetic stirring [ 15 , 16 ], ultrasonic treatment [ 17 , 18 ], etc. Adding a modifying element (Na, Sr, etc.)…”

Effect of Zr, V and Ti on hot compression behavior of the Al–Si cast alloy for powertrain applications

“…They also reported that the combinations exceeding 0.2%Zr and 0.2%Ni in the Al-Si-Cu-Mg base decreased the alloy performance. The previous studies have been focused mainly on determining various material constants in the constitutive equations describing the hot deformation behavior [10,11,[23][24][25][26][27][28][29]. However, according to the authors' knowledge, there is no study on the impact of addition of transition metals, especially Ti, V and Zr in Al-Si-Cu-Mg alloys on the hot deformation behavior.…”

Preparation and properties of Sip/Al composites by spark plasma sintering

“…Several processes have been developed to prepare Si p /Al composites, including melt infiltration [3], squeeze casting [4], spray deposition [5,6] and powder metallurgy [7], etc. In the infiltration or casting process, the molten Al liquid is filled into a silicon particle preform with connected pores inside, which can obtain Si p /Al composites with high Si fraction (>60 vol.%).…”
