Question

Joints of dissimilar metal combinations are widely employed for
different applications requiring certain special combination of
properties as well as to save cost [1–3]. Welding dissimilar materials
is generally more challenging than welding similar ones for differences
in the chemical, physical and mechanical properties of the
base metals [4–6]. Dissimilar joints between stainless steel (SS)
and carbon steel (CS) are widely used in the main steam lines of
power plants, in nuclear reactors, and in petrochemical plants.
Because of their different mechanical property and corrosion property,
the joints of stainless steel to carbon steel (SS–CS) not only
meet the requirements of the service environment but also reduce
the cost. Dissimilar metal joints are characterized by compositional
gradients and microstructural changes which produce large variations
in physical and chemical properties across the joint [7]. So
there are some problems need to be solved in this SS–CS joints.
The problem with the dissimilar metal weld made between CS
and SS is the secondary phase formation due to higher carbon content
of CS than that of SS. Carbon diffusion and subsequent formation
of harmful microstructure in the weld metal is considerable in
joining of carbon steels to stainless steels. Hence, decarburization
and grain growth take place in heat-affected zone (HAZ) of CS
affect the mechanical properties [8].

Answer 2

异种金属组合的焊接接点被广泛应用于要求某种特殊性能组合以及降低成本的各种应用场合[1-3]。焊接异种材料因为基体材料的化学、物理和机械性质的不同，通常比焊接相同材料更具挑战性[4-6]。不锈钢（SS）和碳素钢（CS）之间的异种接合被广泛应用于发电厂的主蒸汽管线、核反应堆和石化工厂中。因为它们不同的机械性质和腐蚀性质，所以不锈钢和碳素钢（SS-CS)的接点不仅满足使用环境的要求，而且能降低成本。异种金属接点的特点是组分上的梯度和显微结构的改变，从而在跨接点的物理和化学性质上产生大的变化[7]。因此在这种SS-CS接点方面还有一些问题需要解决。在CS和SS之间进行的异种金属焊接的问题是由于CS比SS高的碳含量而引起的第二相形成。焊接金属中碳的扩散和其后的有害显微结构的形成在碳钢与不锈钢的接合中相当大。因此，在CS的热影响区发生的脱碳和晶粒生长会影响机械性质[8]。本回答被提问者采纳
