tailieunhanh - The effects of adding silicon carbide SiCp on aluminum alloy and analyzing the fatigue parameters and mechanical properties for metal matrix composites

The low cycle fatigue (LCF) resistance of two different metal matrix composite (MMC) of AA6063 with 2% and 8% by volume silicon carbide (SiCp) particles having particulate size of 37 micron (400 mesh) at room temperature condition has been evaluated under fully reversed strain control testing. | Nội dung Text The effects of adding silicon carbide SiCp on aluminum alloy and analyzing the fatigue parameters and mechanical properties for metal matrix composites Engineering Solid Mechanics 7 2019 367-381 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm The effects of adding silicon carbide SiCp on aluminum alloy and analyzing the fatigue parameters and mechanical properties for metal matrix composites Dr Mazin Mahmood Yahyaa a Aeronautical Techniques Engineering Department Head of Department Bilad Alrafidain University College Iraq ARTICLE INFO ABSTRACT Article history The low cycle fatigue LCF resistance of two different metal matrix composite MMC of Received 2 June 2018 AA6063 with 2 and 8 by volume silicon carbide SiCp particles having particulate size of 37 Accepted 7 July 2019 micron 400 mesh at room temperature condition has been evaluated under fully reversed strain Available online control testing. The influence of volume fraction 2 and 8 vol and strain ratio R -1 are 7 July 2019 Keywords examined. Increasing the content of SiCp results in the degradation of strain control fatigue Low Cycle Fatigue Parameters properties while the transition fatigue life increases. Fatigued samples are examined using scanning Metal Matrix Materials electron microscopy in order to understand the failure mechanism SEM . Microstructural features Cyclic stress-Cyclic Strain Life and failure mechanisms studied through scanning electron microscopy SEM confirmed low cycle SEM of MMCs fatigue failure nature.
