| Abstract: | Research and improve mould technology.Residual austenite that is in the centre of mould produces pearlite or thick upper-bainite at 500 ℃ tempering.This upper-bainite can change into low-carbon martensite and a small block of ferrite in order to reach the longgest service life and reduce final cost of production. |

| Keywords: | die forging technology 5CrMnMo steel martensite lower bainite brittleness crack residual austenite |
