(Sage Publications Ltd, 2021) Hassan, Malik; Hussain, Ghulam; Ali, Aaqib; Ilyas, Muhammad; Malik, Sohail; Khan, Wasim A.; Bal, Burak
The aim of this research was to investigate the effect of pre-rolling temperature on the interfacial properties in delamination modes 1 and 2; and formability in Single Point Incremental Forming (SPIF) of Steel-Steel (St-St) bilayer sheet prepared by roll bonding process. The roll bonding process was performed at three pre-rolling temperatures, 700 degrees C, 800 degrees C, and 950 degrees C, with a constant thickness reduction ratio of 58%. The bond strength and critical strain energy release rate (CSERR) were measured to characterize the interface of St-St bilayer sheet. T-peel test for mode 1 and tensile shear test for mode 2 were conducted to determine the interfacial properties. The formability of St-St bilayer sheet in SPIF was measured in terms of maximum wall angle. The results showed that the increase in pre-rolling temperature from 700 degrees C to 950 degrees C enhanced the bond strength and CSERR, in both mode 1 and 2. The enhancement in bond strength with an increase in pre-rolling temperature was 149.5% and 203% in mode 1 and 2, respectively. However, the increase in CSERR in mode 1 and 2 was 115% and 367%, respectively. The formability of St-St bilayer sheet also showed an increasing trend with an increase in pre-rolling temperature. Moreover, a consistent relation between formability and interfacial parameters was observed. It was also found that to successively deform the bilayer sheet into the desired shape, it is necessary for the sheet to be heated above the critical temperature during fabrication to facilitate good bonding between two sheets.

(Elsevier Sci Ltd, 2025) Yuan, Yanjie; Louhichi, Borhen; Heidarshenas, Behzad; Alrasheedi, Nashmi H.; Bal, Burak; Hussain, Ghulam
Current surface texturing and coating methods exhibit performance improvements but face significant limitations, including inconsistent durability, scalability restrictions, and inadequate integration of their properties. Integrating these approaches can effectively address these challenges. Modern methods, such as laser machining and additive manufacturing, are paving the way for mainstream applications, offering the opportunity to develop new high-performance surfaces in various fields. For instance, combining laser texturing and advanced coating can address durability issues by developing precise patterns and strong adhesion. The combination of surface texturing and coating improves tribological performance and enhances service maintenance by overcoming the limitations of conventional methods. This offers advanced capabilities for various applications, including medical implants and marine environments. In this context, the synergistic application of texturing and coating technologies is expected to be crucial in developing high-performing advanced materials suitable for various applications. This study reviews the progress on synchronizing texturing and coating approaches. Governing mechanisms and controlling factors are identified and discussed. The benefits of applying synergetic approaches to surface performance are recorded. Optimum conditions to realize the best results are determined. Current challenges, emerging trends, and potential solutions to address these issues are proposed.
