Johnson, D E; Patterson, D A

At elevated temperatures, the tensile strength of the M257 alloy was one and one-half to two times that of 1100 aluminum alloy. At these same temperatures the tensile strength of the M-257 aluminum alloy was approximately the same as the 6063 alloy. Some tendency for notch sensitivity was observed in the elevated temperature tensile tests. Inconsistent failure of notched and indented M-257 tensile specimens was encountered in each of the three series of tests. It was concluded that additional tests must be conducted on the M-257 aluminum alloy to more accurately define the deformation behavior of the material. (auth)
