en Investigating the Fracture Toughness and Mechanical Properties of the Two-Layer Al 1050/Mg AZ31B Sheets Fabricated by the Roll Bonding, Considering the Annealing Temperature Effect Research Paper Research Paper This study presents the manufacturing of Al 1050/Mg AZ31B bimetallic sheets using the cool roll bonding process, followed by an investigation of the effect of annealing temperature on mechanical properties and microstructural features. Annealing treatment was performed at 200, 300, and 400 degrees Celsius. Mechanical testing includes tension, micro-hardness, three-point bending, and fracture toughness. Scanning electron microscopy equipped with energy-dispersive X-Ray spectroscopy (SEM-EDX) and X-ray diffraction (XRD) were used to investigate the microstructure in the infiltration zone. Mechanical testing shows that increasing the annealing temperature decreases the tensile strength of the two-layer specimens. Micro-hardness, XRD, and SEM-EDX investigations confirm the presence of intermetallic particles in the penetration zone. The Micro- hardness test showed that with the increase of the annealing temperature, the hardness in the penetration zone of Al 1050/Mg AZ31B increases. This increase in micro-hardness result confirms the presence of harder intermetallic phases with increasing annealing temperature in the penetration zone.   Fracture toughness,Mechanical properties,Al 1050/Mg AZ31B sheets,Roll bonding process,Annealing 11 26 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-1582-3&slc_lang=en&sid=1 Payam Tayebi payamtayebi@ymail.com 1800319475328460020078 1800319475328460020078 No Iran University of Science & Technology ramin hashemi rhashemi@iust.ac.ir 1800319475328460020079 1800319475328460020079 Yes Iran University of Science & Technology
