The microstructure, hardness and tensile properties of Al–15%Mg2Si in situ composite with yttrium addition

Formulation of the Effect of Different Alloying Elements on the Tensile Strength of the in situ Al-Mg2Si Composites

“…Therefore, an extensive literature survey has been performed for available experimental results [22][23][24][25][26][27][28][29][30][31]. The experimental datasets are divided into three sets as training, validation and test dataset to avoid the over fitting problems.…”

Effects of Single Doping and Composite Doping of Yttrium and Antimony on the Structural, Thermodynamic, Mechanical, and Electronic Properties of Mg2Si by First Principles

“…The 6xxx series aluminum alloy is widely used in automobile manufacturing because of its excellent qualities, such as reduced weight and good corrosion resistance [1,2]. Mg 2 Si is the main strengthening phase [3] of the 6xxx series Al alloy, and it possesses a low density and high melting point and impedes grain boundary sliding [4][5][6][7][8][9]. However, the application of the 6xxx series Al alloy is limited due to its brittleness.…”

Evaluation of cutting force and surface roughness in the dry turning of Al–Mg2Si in-situ metal matrix composite inoculated with bismuth using DOE approach

“…Mg 2 Si compounds are prone to the formation of undesirable coarse Chinese script and brittle dendritic morphologies, which would deteriorate the mechanical properties of the materials. Thus, several researches have been done to modify the deleterious morphology of Mg 2 Si particles with addition of strontium (Sr) [11][12][13], phosphorous (P) [14], yttrium (Y) [15], antimony (Sb) [13,16], manganese (Mn) [17], lithium (Li) [18], mischmetal [19], and cerium (Ce) [20]. Moreover, bismuth (Bi) is used as an alloying element in wrought aluminium alloys to promote chip breaking and helping tool lubrication [21].…”
