Ameliorative Corrosion Resistance and Microstructure Characterization of 2205 Duplex Stainless Steel by Regulating the Parameters of Pulsed Nd:YAG Laser Beam Welding

Hany S. Abdo et al.

Summary: In this study, variations in pulse energy were found to affect the microstructure and corrosion efficiency of a weld. Increasing pulse energy led to changes in the fusion zone and heat-affected zone, with a notable increase in the corrosion resistance of the weld material. Electrochemical tests and spectroscopy confirmed these findings, showcasing improved corrosion resistance with higher pulse energies and the presence of an oxide layer on the surface.

Synergistic Strengthening Effect of Reinforcing Spark Plasma Sintered Al-Zn-TiC Nanocomposites with TiC Nanoparticles

Hany S. Abdo et al.

Summary: Al-10Zn-TiC nanocomposite powders were prepared by mechanical alloying with varying reinforcement content, and bulk samples with 10 wt% TiC reinforcement showed a grain size of 17 +/- 08 μm and improved load carrying ability. Microscopic analysis confirmed the presence and distribution of reinforced nanoparticles in the Al matrix, with XRD results showing TiC formation, SEM analysis revealing uniform distribution of particles, and TEM showing clear interface between matrix and TiC nanoparticles. Mechanical properties testing indicated higher strength in nanocomposites due to multiple strengthening mechanisms from nanoscale TiC addition.

Experimental optimization of corrosion rate analysis for AA 5083-Titanium Diboride (TiB2) composites

Gundugandla Kishore et al.

Summary: The study focused on optimizing the corrosion rate through immersion testing by using aluminum alloy 5083 and Titanium Diboride as reinforcement particles. Different factors such as reinforcement percentage, corrosion medium percentage, and immersion time were found to influence the corrosion rate. Experimental design and microstructure analysis were used to determine the optimal corrosion rate.
