“…The bender is the segment where the strand is subjected to its first deformation to follow a radius that changes the process from vertical to horizontal. This deformation induces tensile and compressive stresses at the outer and inner bow respectively, [22][23][24][25] as shown in Fig. 2(b).…”

“…After that, the thermophysical parameters and creep constitutive equation were obtained from the test data. Then, they were applied in the process of straightening a continuous cast slab so as to utilize the creep deformation to complete the straightening [10]. It can be seen that the high temperature creep property has a positive impact on the production and application of materials.…”

A tensile creep test has been carried out to study the high temperature creep mechanism of Q460E steel and thus develop a better understanding about how the creep phenomenon affects the performance of a cast slab. Because the heating process in the solidification method is more similar to the actual solidification process of casting a slab, the high temperature tensile creep test was conducted by using the solidification method. Further observation of the microstructure was carried out after the tensile creep test has been carried out. The microstructure of the Q460E steel after the high temperature tensile creep test and water quenching observed with a metallographic microscope revealed mainly martensite and retained austenite. From the observation with a transmission electron microscope (TEM) it could be found that dislocation and its substructure were the root cause which triggered high temperature creep deformation of the Q460E steel. In addition, the formation of a subboundary also provided the impetus to creep deformation.
