On the hot working characteristics of INCONEL alloy MA 754 using processing maps

Hot workability is concerned with the extent to which a material plastically deforms during shaping at high temperatures without the occurrence of flow localization or fracture. A simple condition for delineating the regions of unstable metal flow in the processing maps is suggested. The applicability of this criterion has been verified using the test data of INCONEL alloy MA 754 with microstructural observations. A hot workability map of this material is established for shop floor applications.
