| Abstract: | Heat treatment tests of normalizing,quenching and temperature tempering,double quenching are carried on the material ZG25Mn for the axle box base of electric locomotive.This paper compares and analyzes the microstructures and mechanical properties of ZG25Mn by different heat treat ment process.It expounds the strengthening and toughening theory of double quenching and considers that double quenching can improve the microstructure and crease strength and toughness.After double quenching,the general properties of the axle box base have been improved effectively,which is the same as the properties of 8K electric locomotive axle box base. |
