a study on ultrasonic vibration cutting of Low Alloy Steel
Journal of Materials Processing Technology, 2007Co-Authors: Chandra Nath, Mustafizur Rahman, S. S K AndrewAbstract:Abstract High quality mirror surface machining of hard and brittle materials such as glass, ceramics, tungsten, Ni-based and Ti-based Alloys has become more important in recent advanced technological applications; as these materials are widely used as aspheric shapes in optical and electronic devices, aerospace industries, household works etc. Much research has been conducted covering various cutting parameters to optimize machining conditions of such difficult-to-machine materials. Low Alloy Steel (DF2), a hardened Steel, is a workhorse material in all industries, especially in chemical process industries due to its Lower cost, good mechanical properties, weldability, and corrosion resistance at moderate temperatures. High quality surface finish is essential in most of the cases and this cannot be obtained by conventional turning (CT) process. Ultrasonic vibration cutting (UVC) has been applied to study the tool wear, cutting forces, chip formation and surface roughness under specified cutting conditions over a range. This paper investigates the effects of UVC in cutting of DF2 material, on abrasive wear and on the transition of Low to high tool wear rate in the machining of the same material. Finally, it compares the UVC with CT in machining of DF2 for different cutting parameters. It is observed with photography that UVC process results in better surface finishes as compared to CT, and UVC requires Lower cutting forces than in the CT process. It is also found that UVC has Lower tool flank wear rate compared to CT under all cutting conditions.

controlling angular distortion in high strength Low Alloy Steel thick plate t joints
Journal of Materials Processing Technology, 2019Co-Authors: Chaohua Zhang, Suo Li, Yifeng Wang, Dean DengAbstract:Abstract Both numerical approach and experimental method were employed to investigate angular distortion and welding residual stress of thick-plate multi-pass T-joints made of high strength Low Alloy Steel. The efficiency of controlling angular distortion by the structural restraint method and the presetting method was quantitatively examined based on the simulation results and the experimental measurements. The structural restraint method can reduce angular distortion of the T-joint by 73%, while the presetting method can almost completely eliminate the angular distortion through setting an appropriate initial presetting. The structural restraint method can slightly mitigate the final welding residual stress, and the presetting method has a negligible influence on the welding residual stress distribution.

Effect of Cu on corrosion behavior of Low Alloy Steel under the simulated bottom plate environment of cargo oil tank
Corrosion Science, 2016Co-Authors: Xuehui Hao, Ini Ibehe Nabuk Etim, Jie Wei, Junhua Dong, Wei KeAbstract:The effect of Cu on the corrosion behavior of Low Alloy Steel under the simulated bottom plate environment of cargo oil tank was investigated by using gravimetric test, SEM, EDS, XPS, XRD and electrochemical measurements. The results indicate that the corrosion resistance of 16MnCu Steel was higher than that of 16Mn Steel, which was related to the deposition of nano-sized Cu particles on the surface. The deposited Cu might suppress both the anodic dissolution of the ferrite and hydrogen evolution reaction on the cementite, leading to the reduction of the galvanic effect caused by the residual cementite.

effect of sulphur dioxide on the corrosion of a Low Alloy Steel in simulated coastal industrial atmosphere
Corrosion Science, 2014Co-Authors: Wenjuan Chen, Junhua Dong, Wei KeAbstract:Abstract This investigation aims to study the effect of SO 2 on the corrosion of a Low Alloy Steel in simulated coastal industrial atmospheres. The results indicate that the corrosion weight gain of the Steel firstly increases with increasing SO 2 content to a certain level and then decreases with further increasing the SO 2 content. Besides, higher SO 2 content promotes the formation of α-FeOOH and inhibits the formation of γ-FeOOH. Moreover, it seems that the deterioration effect of SO 2 to Steel corrosion is not obvious in the initial corrosion stage and SO 2 begins to accelerate the Steel corrosion as the corrosion process increases.
