“…As the typical low melting point element, Sb also has high tendency to segregate at the grain boundaries [45]. The segregation of Cu and Sb at grain boundaries of steel could weaken the grain boundaries, and the weakened grain boundaries were cracking under thermal stress [46]. Moreover, due to the typical condition of non-grain-boundary equilibrium segregation during the cooling process of the billet, the segregation of elements at grain boundaries is also an important factor leading to the crack in the billet.…”

This paper characterizes the surface crack morphology and elements of 09CrCuSb steel continuous casting slabs and studies the high-temperature thermo-plasticity of continuous casting slabs using a Gleeble 3500 thermal simulator. Combining the macro/micro fracture morphology and microstructure characteristics, the formation rules of slab cracks are discussed. The research results show that the increase in Ae3 temperature caused by changes in alloy elements results in the precipitation of a thin, film-like coexisting ferrite along the grain boundaries at a certain temperature, as well as the element segregation behavior of low-melting-point alloy elements at the original austenite grain boundaries, which are the main factors inducing cracks in 09CrCuSb steel continuous casting billets. The plasticity of 09CrCuSb steel at high temperatures is poor at 800~900 °C. In continuous casting process control, it is necessary to try to avoid long-term stay of the billet at this temperature range.

“…Chen [13] et al achieved the joining of 316 stainless steel and CuSn10 using selective laser melting (SLM) and investigated the microstructure of the bimetallic interface, which revealed that thermal cracks appeared near the joint of the steel side. Chen et al [14] realized the connection of steel and tin bronze using arc cladding technology, and observed the penetration cracks at the bimetallic connection interface which extended to the interior of steel along the grain boundary. The above researches show that, conventional fusion welding of copper alloys to steel has a series of problems such as difficult fusion on the copper side, thermal cracking and degradation of the properties of the base material.…”

Diffusion bonding technology was used to realize the connection of 42CrMo steel and tin bronze, and the effects of bonding time and nickel interlayer on the microstructure and mechanical properties of the joint were studied. The results show that: When 42CrMo steel and tin bronze are directly diffusion bonded, at 850 ℃ and 4MPa, the shear strength of joint first increases and then decreases with the increase of bonding time. When the bonding time is 60 min, the thickness of the diffusion layer is about 0.5μm, the shear strength of the joint reaches a maximum of 152MPa, and the fracture shows mixed fracture characteristics of brittleness and ductile. After adopting Ni foil as the interlayer metal, both 42CrMo steel/Ni and Ni/tin bronze interfaces formed obvious diffusion layers of about 11 μm and 50 μm, respectively, a granular discontinuous distribution of (Cu,Ni)3Sn formed on the Ni/tin bronze side, the shear strength of the joints is elevated up to 221 MPa, and the fracture is characterized by ductile fracture.
