MECHANICAL PROPERTIES AND ELECTRICAL RESISTIVITY OF THE HEXAGONAL AG-AL INTERMETALLIC PHASE.
Abstract
The mechanical properties and electrical resistivity of a number of alloys within the composition range of the Ag-Al hexagonal intermediate phase were determined. All the alloys were extruded to rod, swaged, and finally annealed at either 850, 600, or 400F and quenched. The results show that the binary alloys annealed at 400F are strongest; tensile strengths of about 100,000 psi and yield strengths of about 85,000 psi were obtained. The elongation and reduction in area of the binary alloys remained fairly constant at 12 to 18 percent in all the alloys containing less than about 35 a/o Al. With greater amounts of Al the alloys became less ductile. The Ag-Al zeta-phase alloys were shown to be hardened and strengthened slightly, without loss of ductility, by the addition of small amounts of Zr. (Author)
