Fracture behavior of the Fe-8Al alloy FAP-Y
The tensile and impact properties of two heats of the reduced aluminum alloy FAP-Y have been measured and compared to the Fe{sub 3}Al alloy FA-129. The FAP-Y material has similar yield strengths up to 400{degrees}C, and much better ductility and impact properties, as compared to the FA-129. Despite excellent room-temperature ductility, the ductile-to-brittle transition temperature is still quite high, around 150{degrees}C. The material is found to be strain-rate sensitive, with a significant increase in the yield strength at strain rates of about 10{sup 3} s{sup {minus}1}. It is believed that this strain-rate sensitivity is responsible, at least in part, for the high ductile-to-brittle transition temperature.
