Two-Stage Heat Treatment of Steel 30CrMnSi and Its

The effect of cooling medium on the microstructure and mechanical properties of steel 30CrMnSi is studied after different heat treatment.Microstructure is studied by scanning electron microscopy,energy dispersion analysis,and fractography.Impact strength,shear punch stress,friction coefficient,and wear resistance in pin-on-disk tests are determined.The reinforcement role of deep cryogenic treatment on the Deep cryogenic treatment (DCT) is believed to have superior performance in coordination with traditional heat treatment.In present work,the effect of DCT combined with inter-critical quenching treatment on the mechanical properties and microstructure of 30CrMnSi alloy structural steel was investigated.The effects of RE on Toughness of 30CrMnSi wearresistant The effects of RE (La and Ce) on toughness of 30CrMnSi wearresistance cast steel have been investigated by means of analysing microstructures and mearsering the properties of the steel with and without RE.The results show that RE can refine the ascast microstructures,hinder or eliminate needle and network ferrite,increase the
