摘要	Laves phase has been widely accepted to cause the impact brittleness of 9-12Cr martensitic heat-resistant steels after long time aging at elevated temperatures. However, in the present research, the impact toughness of the already brittle P92 steel aged at 600 degrees C for 2035 h could be restored to the original level by reheating at 700 degrees C for 1 h, with Laves phase barely changed. This interesting result strongly indicated that the presence of Laves phase might not be the real reason for the impact brittleness. (C) 2015 Elsevier B.V. All rights reserved.
