- (1)
- Uniaxial tensile testing of the SSC bar with metal deposition and the hot rolling method at 25 °C exhibited a yield point of 423 MPa and ultimate tensile strength of 602 MPa, while the elongation reached 22%. The positive and negative bending experiments showed no cracks during bending;
- (2)
- Vickers hardness in the transition zone was higher than in carbon steel and in the base metal of stainless steel, and the transition zone was divided into two districts: one was martensite phase region with the maximum hardness of 545 HV0.2 that was conducted by mutual diffusion of Cr and C, as well as Mn. The other was the region of duplex phases of ferrite and martensite which were located adjacent to the stainless steel zone;
- (3)
- The SSC rebar with a flat interface possessed a metallurgical bonding interface nearby of which the microstructure showed a relatively clean state;
- (4)
- EPMA line scan showed the diffusion behavior of key elements measured at the interface, among which the diffusion distances of Cr and Mn reached 32 µm and 25 µm, respectively.
