The Effect of Fiber Orientation and Morphology on the Tensile Behavior of Al Ni Whisker Reinforced Aluminum


The tensile strength of Al-Al3Ni was found to decrease rapidly with increasing angle between the whisker alignment and the tensile axis; however, the lowest value was more than twice that of the matrix alone. Except for specimens having whiskers aligned nearly parallel to the test axis, the predominant failure mode was by shear of the matrix. Blade-like whiskers were found to provide more transverse reinforcement (10 per cent) than needle-like whiskers. The results were compared with the analyses of Stowell and Liu, Kelly and Davies, and Azzi and Tsai.
