“…3 ) can be identified on the faceted areas even inside the dimples [4]. Joint fracture behavior is initiated by the brittle fracture of scale inclusions and growth around the internal oxides [5]. Surface scale is the most important factor of sound joining, therefore the joint surface must descale before joined together.…”

In this study, the joint strength and microstructure of carbon steels welded by an super-deformation joining process in air were investigated. The two block of model steels are overlapped and heated. The steels are welded with 1000% deformation at approximately 1000°C.The joint strengths are evaluated by uniaxial tension testing. The joint microstructures and fractured surfaces are investigated with OM and SEM. The results revealed that the mechanical properties of joint are close to the matrix’s, the grains adjacent to the interface are merged into one grain, which indicates that both blocks are soundly joined,fracture surface was covered with dimple indicating ductile fracture occurred. Joint fracture behavior is initiated by the brittle fracture of scale inclusions and growth around the internal oxides. Surface scale is the most important factor of sound joining.

“…The creep resistance performance of the material is better in helium gas than in the air, which shows that the influence in different levels of oxidation is led to the creep resistance properties of materials. Shutao Liu et al [9][10][11][12] analyzed the T23 steel reheater tube explosion accident of a certain power plant and found that it is caused by oxidation in the outer wall of the T23 tube.…”

Using scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS), the morphology observations and composition analtyses of a T23 steel oxidized in water vapor for 10~150min at 600°C were investigated, to study the initial formation mechanism. The result showed that the initial oxidation film was changed from acicular to flake shape. The second oxidation film layer appeared after oxidation for 40 min, and obvious double oxidation film structure was formed after 150 min with inner Cr-rich protective isometric crystal and outer Fe primarily columnar crystal.The oxide was Fe-rich phase in the whole oxidation process.
