Si₃N₄ Nanoparticle Addition to Concentrated Magnesium Alloy AZ81: Enhanced Tensile Ductility and Compressive Strength

Table 4

Results of tensile testing of monolithic AZ81 and derived nanocomposite. Linked with Figure 3.

Material	0.2% TYS; (MPa)	UTS; (MPa)	Failure strain; (%)	Energy absorbed, EA; (MJ/m^3)^a
AZ81	227 ± 3	321 ± 2	8.7 ± 0.9	26 ± 3
AZ81/1.5 vol% Si3N4	229 ± 9 (+1)	328 ± 7 (+2)	10.7 ± 0.9 (+23)	33 ± 3 (+27)

^aEnergy absorbed until fracture that is, area under the engineering stress-strain curve until the point of fracture (obtained using EXCEL software).
( ) Brackets indicate % change with respect to corresponding result of monolithic alloy.
