Abstract:

High strength Al2O3 fibers whiskers have been used to reinforce 80-20 Ni-Cr alloy and Fe on a laboratory scale. The tensile strength of the Ni-Cr alloy was increased 28 by the incorporation of 3.8 wt- Al2O3 whiskers, with corresponding lower levels of reinforcement at lower fiber loadings. The tensile strength of H-reduced Fe was increased both at room temperature and at 900 F at room temperature the average increase, with 8 fiber loading was 34 at 900 F the average increase with the same amount of fiber was 30. The fibers were randomly oriented in the matrix. Some insight into the role of oxides in forming this bond has been gained by melting the metal on Al2O3 tablets and observing the resulting interactions. Author
