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

Table 5

Results of compressive testing of monolithic AZ81 and derived nanocomposite. Linked with Figure 4.

Material	0.2% CYS; (MPa)	UCS; (MPa)	Failure strain; (%)	Energy absorbed, EA; (MJ/m^3)^a
AZ81	93 ± 7	510 ± 19	19.9 ± 2.7	74 ± 9
AZ81/1.5 vol% Si3N4	112 ± 19 (+20)	543 ± 5 (+6)	20.5 ± 1.3 (+3)	92 ± 9 (+24)

^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.
