نویسندگان
چکیده
In the present study, high-speed steel (HSS)/ductile cast iron (DCI) composite roll was manufactured by electroslag remelting cladding (ESRC) technology. The compositional variation, grain size, microstructure, hardness, and tensile strength of HSS layer bimetallic interface were investigated systematically. obtained results illustrated that chemical composition (HSS) changed dramatically due to surface melting core mechanical mixing liquids. different solidification rates compositions in regions led great variations carbide content, hardness. addition, a transition zone (about 9.47 mm) generated between DCI elemental migration diffusion bimetals. Carbides types, morphologies, sizes, had direct influences on interfacial properties.

TiC Reinforcement Composite Coating Produced Using Graphite of the Cast Iron by Laser Cladding
In this study, a TiC-reinforced composite coating was produced to improve the wear resistance of a pearlite matrix grey iron using a pre-placed Ti powder by laser cladding. Results of scanning electron microscopy (SEM), X-ray diffractometer (XRD), and energy dispersive X-ray spectroscopy (EDS) confirmed that the coating was composed of TiC particles and two kinds of α-Fe phase. The fine TiC par...
متن کاملTechnology for Electroslag Remelting with Rotation of the Consumable Electrode
is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refining in the specially chosen slag and for the crystallization of the metal in the case of ESR. However, the need for a two-stage metallurgical conversion (essent...
متن کاملEffect of Current on Structure and Macrosegregation in Dual Alloy Ingot Processed by Electroslag Remelting
Macrosegregation is a very common problem for the quality control of all cast ingots. The effect of current on the structure and macrosegregation in dual alloy ingot processed by electroslag remelting (ESR) was investigated experimentally with various analytical methods. In this study, the electrode consisted of NiCrMoV alloy bar (upper part) and CrMoV alloy (lower part) with a diameter of 55 m...
متن کاملThe Structural Evolution and Segregation in a Dual Alloy Ingot Processed by Electroslag Remelting
The structural evolution and segregation in a dual alloy made by electroslag remelting (ESR) was investigated by various analytical techniques. The results show that the macrostructure of the ingot consists of two crystallization structures: one is a quite narrow, fine, equiaxed grain region at the edge and the other is a columnar grain region, which plays a leading role. The typical columnar s...
متن کاملTribological Behavior of Reinforced and Unreinforced High Chromium Cast Iron
In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16 volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...
