The significance of machining diagram to process parameters of 34CrMo4 steel

According to the flow stress data, it can be found that deformation temperature and strain rate have great influence on the plasticity of 34CrMo4 steel. When 34CrMo4 steel is deformed at moderate temperature and high temperature, dynamic recovery or dynamic recrystallization will occur.

The purpose of deformation of 34CrMo4 steel is not only to obtain the required product shape, but more importantly to ensure that 34CrMo4 steel has excellent properties and ideal microstructure. In order to avoid internal or external defects that damage material properties during deformation of 34CrMo4 steel, reasonable processing technology, such as deformation temperature and deformation rate, should be selected. The machining diagram is a set of theory developed by considering the above conditions and combining with the specific deformation conditions of 34CrMo4 steel.

It can truly reflect the evolution of the internal structure of 34CrMo4 steel during deformation and accurately evaluate the machinability and formability of 34CrMo4 steel. It is of great significance to determine the process parameters of 34CrMo4 steel.
