Initial heat-treatment studies are reported in which the effects of quenching rate upon room temperature ductility of iron-aluminum alloys were investigated. Quenching media included bciling water, oil at room temperature, and oil at 100 deg C. Experimental results are tabulated. No definite trends in tensile properties were observed with differences in quenching rate. Electropolishing techniques for use in preparation of specimens are discussed in relation to determination of microcrack effects on tensile tests. (For preceding period see AECU-4528.) (J.R.D.
