| Abstract: | This paper deals with the effect of hot forging on microstructures and mechanical properties of newly developed super high strength steel G50 by a series of upsetting forging processes and heat treatment.The forgeability of this newly developed super high strength steel was also tested. Experimental results show that G50 super high strength steel has excellent hot forgeability.As long as a standard heat treatment was used,similar microstructures and mechanical properties were obtained,no matter what pre processes were employed. |
