Experimental characterization of the mechanical properties of railway wheels manufactured using class B material

The unstoppable quest for low-cost reinforcing agent gingered the enthusiasm towards developing and utilising the agro-based waste product as reinforcement since they are promptly accessible, sustainable, and inexpensive to purchase. In this study, AA6061/rice husk ash matrix composites were produced through metallurgical stir casting techniques. Different weight percentages of reinforcement in the range of 2%, 4%, 6%, and 8% were used to fabricate the composites. The reinforced composites were characterized by SEM/EDS for microstructural study. The mechanical behaviour was examined for all the produced samples. SEM/EDS analysis revealed the presence of silica, a major constituent of rice husk ash in the produced composites. The results of the mechanical behaviour show that upgrading the weight percentage of reinforcing agent increases the mechanical properties. AA6061/8% rice hush ash generated a consistent rise with filler concentration in comparison with the aluminium alloy in all operating functions.

The emergence of nanocomposite particulate with the increasing demand for opto-electrical properties for defence application has necessitated this study. In this work, an attempt was made to develop Zn-CeO 2 /Zn-CeO 2-Al 2 SiO 5 thin film composite on A356 mild steel using electrodeposition technique. The developed coating was attained in 2 V for 10 min at a constant current density of 1.5 A/cm 2 and pH of 4.5. The mass concentration of Al 2 SiO 5 was varied, ranging from 0 to 15 g. The composite coatings were characterized using Scanning electron microscope equipped with energy dispersive spectrometer (SEM/ EDS). The corroding properties of the coated and uncoated sample were examined through potentiodynamic polarization technique via Autolab PGSTAT 101 Metrohm potentiostat/galvanostat with NOVA software of version 2.1.2 in 3.65% NaCl. The electrical characterization was carried out using voltageammeter meter and Keithley 2400 series source meter application tester. The opto-electrical investigation was done using a solar simulator with maximum intensity of 1000 W/m 2 under an air mass of 1.5 at a working intensity of 750 W/m 2. The outcome of various test and characterizations revealed that the electrodeposited Zn-CeO 2 /Zn-CeO 2-Al 2 SiO 5 possessed good stability, improved microstructural qualities, better electrical conductivity and outstanding corrosion resistance.

“…The steel joints were MAG welded and characterized regarding fatigue life. Railway rails are subjected to complex dynamic loading, which promotes the fatigue crack propagation phenomenon [1] As newer demands for faster and more heavily loaded trains emerge [2]. To ensure railway system security and reduce service costs, it is required to characterize the mechanical behavior of the zone containing metal ripping induced by a manufacturing flaw that may be the cause of breakage [3].…”

The wheels and rails of the train, tram etc. are often verified from their microstructure and plastic deformation, which usually appear in the outer layer of a wheel and rail, to analyse the causes of geometrical defects by monitoring the applied loads and variation of the temperature as suggested in the literature. This paper studies the effect of thermal stress applied with variations of the loads in contact on wheel/rail for the tramway, tracking through the state of the rail to discover the causes of geometric defects started by temperature variations and loads, and applying these variations of temperature and loads to know its resistance to these climatic conditions. 3D model of temperature distrubtion and heat flow in the wheel and the rail ER6 and ER7 has been developped using the finite element method based on the COMSOL Multiphisics.
