All these blades were manufactured using a 718 nickel base alloy. The performed study consisted in a fractographic analysis by scanning electron microscopy and a microstructural study using both scanning and optical microscopy. Phases which were present in the fracture surfaces were identified by means of X-ray energy dispersive spectrometry. As a result of this labour the failure was attributed to the impact of sand and stones; that is the so-called foreign object damage mechanism.9enginfo:eu-repo/semantics/restrictedAccessjournal article10.1016/j.engfailanal.2007.10.002Compressor bladesForeign object damageNickel base alloysGeneral Materials ScienceGeneral Engineeringhttp://www.scopus.com/inward/record.url?scp=40949163117&partnerID=8YFLogxK
