摘要：
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 pro-cessing 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. (C) Munksgaard, 2000.
