ANALYTICAL AND EXPERIMENTAL INVESTIGATIONS OF THE FRACTURE -- MECHANISMS OF CONTROLLED POLYPHASE ALLOYS.
Abstract
The results of continued investigations of the unidirectionally solidified eutectic alloys Cu-Cr, Al-CuAl2, and Al-Al3Ni are presented. Microbend tests were made on Al-CuAl2 eutectic specimens for the 30, 45, and 60 deg plate orientations to complete the plate orientationstress axis study. The results indicate a nonlinear decrease in strength from a maximum of 49,800 psi for the parallel case (zero degrees orientation) to a minimum of 16,700 psi for the normal case (90 deg orientation). The composite elastic modulus has been determined graphically to be about 14.5 x 10 to the 6th power psi (depending upon phase-stress axis orientation). (Author)
