A homogenous carbon nanotube (CNT)-Al composite powder used for 3D printing was prepared by insitu impregnation of carbon nanotubes (CNTs) within Al powder. The use of powder substrates produced the unidirectional gas flow and made the synthesized CNTs bend and encircle on the surface of Al powder. The newly made CNT-Al composite powder thus had a ...

Investigation of carbon steel corrosion influenced by in-situ microbial communities can provide reliable information about microbiologically influenced corrosion (MIC) in the oil and gas field. Here, we investigated the 90-day corrosion behavior of Q235 carbon steel influenced by interior deposit microflora of an in-service pipeline using open circ...

Squeeze overcasting has emerged as an attractive option for casting of Al alloys in terms of mechanical properties. The attainment of the desired magnitude of these properties is challenging in overcasting due to the involvement of a number of process parameters. In this study, the effects of insert preheat temperature (TI) along with pouring tempe...
Manganese-bearing intermetallic compounds (IMCs) are important for limiting micro-galvanic corrosion of magnesium-aluminum alloys and can initiate cracks under tensile load. Here, we use electron backscatter diffraction (EBSD), deep etching, and focussed ion beam (FIB) tomography to investigate the types of Al-Mn phases present, their faceted growt...
Hard TiN coating (with a Vickers hardness higher than 1300 HV) on soft steel (smaller than 200 HV) has a great tendency to mechanical failure due to the significant mismatch in hardness. To tackle this issue, a Fe2Ti metallurgically bonding interlayer was designed and fabricated in between TiN coating and stainless steel 316L substrate. Results rev...

This study investigates the effect of stainless steel (STS) 308 L and high-entropy alloy (HEA) filler metals on gas tungsten arc (GTA) welding. The weldability of the cast CoCrFeMnNi HEAs was determined based on the microstructural and mechanical properties of the welds. The cast HEA exhibited larger dendrite packets than the weld metals (WMs). The...
