摘要

The influence of precipitation and grain size on the hot ductility of alloy C-276 ESR ingots has been determined. Tensile tests were performed in the temperature range of 950 to 1200 deg C at a strain rate of 6.1/se. The precipitation of the P phase in this alloy revealed a detrimental influence on the hot ductility, because these precipitates tend to fracture prior to grain boundary sliding and dynamic recrystallization during deformation, and hence favor a low ductility cleavage fracture.
