Al-based metal matrix composites reinforced with Fe_(49.9)Co_(35.1)Nb_(7.7)B_(4.5)Si_(2.8) glassy powder: Mechanical behavior under tensile loading

摘要

The mechanical properties of Al-based composites reinforced with different volume fractions of Fe_(49.9)Co_(35.1)Nb_(7.7)B_(4.5)Si_(2.8) glassy particles are investigated under tensile loading. The results reveal a significant strengthening of the composites with respect to the unreinforced Al-based matrix. The comparison of the mechanical data with those regarding other Al-based composites reinforced with glassy particles indicates that metallic glasses are not only effective reinforcements under compression but also under tensile loading.
