“…Recently, Sallam et al [26,27] suggested preheating the austenitic stainless steel reinforcements to about 700 • C to reduce temperature losses in the bimetallic casting process. Kang et al [28] and Norouzifard et al [18] also found that the preheating of reinforcements positively affects the final properties of copper composites. Based on these points, the present work's main objective was formulated.…”

The growing applications of iron/copper bimetallic composites in various industries are increasing. The relationship between the properties of these materials and manufacturing parameters should be well understood. This paper represents an experimental study to evaluate the effect of reinforcement (steel rod) preheating temperature on the mechanical properties (bond strength, microhardness, and wear resistance) of copper matrix composites (QMMC). In preparing the QMMC samples, the melted copper was poured on a steel rod that had been preheated to various temperatures, namely, room temperature, 600 °C, 800 °C, and 1200 °C. Properties of the QMMC (interface microstructure, interfacial bonding strength, microhardness, and wear) were investigated. The experimental results revealed that the best bond between the copper matrix and steel rod formed only in the composites prepared by preheating the steel rods with temperatures lower than the recrystallization temperature of steel (723 °C). This is because the oxide layer and shrinkage voids (due to the difference in shrinkage between the two metals) at the interface hinder atom diffusion and bond formation at higher temperatures. The microhardness test showed that preheating steel rod to 600 °C gives the highest value among all the samples. Furthermore, the QMMC’s wear behavior confirmed that the optimization of preheating temperature is 600 °C.

“…Gladkovsky et al prepared pure copper and low-carbon steel sandwich composites by explosive welding, and the interface microstructure and mechanical properties of the composites were investigated in detail [15]. However, considering the cost and efficiency problems in industrial production, solid-liquid casting is a more promising method to prepare bimetallic composites [16,17].…”

In the present study, mechanical vibration was applied in the preparation of the tin bronze/steel bimetal composite by the solid–liquid bonding, and the effects on the microstructure and mechanical properties were investigated. The results show that mechanical vibration refines the microstructure of tin bronze and accelerates the interdiffusion between the two components, resulting in the improvement of the bonding strength and Brinell hardness. With the vibration frequency of 30 Hz, the composite strength and hardness are significantly improved. The finite element method further shows that the exciting force and homogeneous temperature field caused by the vibration are the main reasons for the microstructure optimisation. HIGHLIGHTS The tin bronze/1010 steel bimetallic layered composites with homogeneous microstructure are prepared by solid–liquid bonding under the mechanical vibration field. The interface thickness can be increased by applying mechanical vibration to the solid–liquid bonding process of the bimetals. Combined with the results of finite element simulation, the effect mechanism of the mechanical vibration in the preparation process was discussed. With the application of mechanical vibration, the hardness and interfacial bonding strength of the bimetals are obviously improved, and there is an optimal vibration parameter.
