The mechanical and structural properties, residual stress state and wear performance of the specimens were investigated. The results show that precipitation has a crucial influence on the mechanical properties and wear performance of a Heusler alloy. The hardness and wear resistance of the specimens improve with an increase of precipitation density. These precipitates are associated with Cu-rich and Al-Cu lamellar structures. The density of these precipitates reveal two certain Al2Cu peaks at an aging time of 90 minutes, and 150 minutes for the annealed specimens.eninfo:eu-repo/semantics/closedAccessResidual stresswear performanceagingHeusler alloyArticle10.3139/120.1112812-s2.0-85060027755601Q25661WOS:000455084300008Q4
