“…excellent ductility and superior weld ability) of the latter component, while maintaining excellent wear resistance of the former component [6][7][8][9][10][11][12][13][14][15][16]. According to previous research, the HCCI/LCS bimetal can be fabricated by composite casting [6][7][8][9][10][11][12], diffusion bonding [13,14] and cast cladding with hot rolling [15,16]. Oh et al [6] and Kim et al [7] reported an advanced duocasting method in which the HCCI ($27 wt% Cr) was cast first, and then inserted into the other mould to cast the LCS.…”

“…The bonding interface was defect-free with a good diffusion connection. Xiong et al [10,11] [12] proposed a liquid-liquid composing process by pouring HCCI ($22 wt% Cr) and LCS into the same cavity successively to produce bimetallic linear. The combination region between the components was staggered like dog-tooth without mixture of alloys.…”

a b s t r a c tThe objective of this study is to develop a hot diffusion-compression bonding process for cladding low carbon steel (LCS) to high chromium cast iron (HCCI) in solid-state. The influence of temperature (950-1150°C) and strain rate (0.001-1 s À1 ) on microstructure, hardness and bond strength of the HCCI/LCS bimetal were investigated. The interface microstructure reveals that the unbonded region can only be found for 950°C due to lack of diffusion, while the intergrowth between the constituent metals occurred at and above 1100°C. When bonding temperature increases to 1150°C, a carbide-free zone was observed near the interface on the HCCI layer, and the thickness of the zone decreases with an increase of bonding strain rate. These evolutions indicate that the bond quality was improved by raising temperature and reducing strain rate due to the increase of element diffusion. The hot compression process of the bonding treatment not only changes the carbide orientation of the HCCI, but also increases the volume fraction of Cr-carbide. Based on the microstructural examinations and mechanical tests, the optimum bonding temperature and bonding strain rate are determined to be 1150°C and 0.001 s À1 , respectively.

“…Therefore, this technology can be significantly competitive for the commonly used technologies of surfacing by welding and thermal spraying because, in addition to its economic advantages, it does not generate opportunities for the development of cracks in the heat-affected zone that may arise as a result of making the layer by using the welding method. In general, the technology of cast bimetals containing a working layer and a base part is carried out based on two systems; i.e., liquid-liquid [1,2] and liquid-solid [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. An example of the former is a technology in which two independent gating systems are made, which guarantees a two-stage filling of the sand mold cavity.…”

“…The basis technology of layered castings made in a liquid-solid system is the so-called method of mold cavity preparation. In this manufacturing method, the element enriching the surface of the casting is placed in the mold in the form of a granular [3][4][5][6][7][8][9] or monolithic [10][11][12][13][14][15][16] insert directly before the molten metal is poured. Therefore, this paper presents possibilities of using a Cr-base alloy as a granular insert and high-chromium and chromium-nickel alloy steels as monolithic inserts.…”

In this paper, we presented the technology of layered castings based on the founding method of layer coating directly in the cast process known as the method of mold cavity preparation by monolithic or granular material of insert. Prepared castings consist of two fundamental parts: the base part and working part (layer). The base part of a layered casting is usually typical foundry material (i.e., pearlitic grey cast iron with flake graphite or ferritic-pearlitic carbon cast steel), whereas the dependence of an insert type (i.e., monolithic or granular) working part (layer) is suitably plated with ferritic and austenitic alloy steels or a layer from a Cr-base alloy. The ratio of thickness between the base and working part is between 8:1 and 10:1. The quality of the layered castings was evaluated on the basis of ultrasonic non-destructive testing, structure, and selected usable property research. According to work out technology, the prepared layered castings can work in conditions that require high heat resistance and/or corrosion resistance from the working surface layer of an element in a medium of industrial water, for example. Moreover, in the case of applying an insert based on Cr-base alloy powder on the working surface layer, it is possible to obtain high hardness and abrasive wear resistance.

“…Hence the shaping of them is usually carried out by casting technology or spray forming in liquid state. Although some investigations have concentrated on the development of the laminated components with HCCI and low carbon steel (LCS) or medium carbon steel (MCS) prepared by cast or diffusion bonding [4,15,16,[20][21][22] to improve their impact resistance, the workability of the brittle HCCI with ductile metallic lamination has not been discussed till now. It is worth mentioning that the laminated components such as bimetal hammer, composite liner and cladding roller have been used in applications where require excellent wear resistance and sufficient toughness.…”

Journal of Iron and Steel Research International, 22 (5), 438-445. Interface analysis and hot deformation behaviour of a novel laminated composite with high-Cr cast iron and low carbon steel prepared by hot compression bonding AbstractA hot compression bonding process was developed to prepare a novel laminated composite consisting of highCr cast iron (HCCI) as the inner layer and low carbon steel (LCS) as the outer layers on a Gleeble 3500 thermomechanical simulator at a temperature of 950 °C and a strain rate of 0.001 S -1 . Interfacial bond quality and hot deformation behaviour of the laminate were studied by microstructural characterisation and mechanical tests. Experimental results show that the metallurgical bond between the constituent metals was achieved under the proposed bonding conditions without discernible defects and the formation of interlayer or intermetallic layer along the interface. The interfacial bond quality is excellent since no deterioration occurred around the interface which was deformed by Vickers indentation and compression test at room temperature with parallel loading to the interface. After well cladding by the LCS, the brittle HCCI can be severely deformed (about 57 % of reduction) at high temperature with crack-free. This significant improvement should be attributed to the decrease of crack sensitivity due to stress relief by soft claddings and enhanced flow property of the HCCI by simultaneous deformation with the LCS.
