The wear mechanism maps were constructed by correlating the microstructures of worn surfaces with different test parameters. The severe and catastrophic wear mechanisms like delamination and melt wear were wider in base and composite, while in the case of engineered composite, these zones are significantly narrow down. Due to the presence of thermally stable in-situ TiB<inf>2</inf> particles and bimodal precipitates in engineered composite, the material showed sufficient resistance against wear induced deformation. Furthermore, the study established scientific knowhow on high-temperature wear induced deformation behavior by analyzing microstructural evolution in wear subsurface zone. © 2024High temperature engineeringMagnesium alloysMetallic matrix compositesMicrostructural evolutionParticle reinforced compositesReinforced plasticsThermal EngineeringTitanium alloysWear of materialsWear resistanceZone meltingHighest temperatureIn-situ compositeMechanism mapsMg in-situ composite, tribological behaviorSubsurface analyzeTiB 2Tribological behaviourTribological wearsWear mechanism mapWear mechanismsTribology
