Abstract
This experimental study investigates the influence of electroplasticity on microstructural evolution and mechanical response during AA2024 plate forming processes. Direct current levels of 90 A, 100 A, and 110 A, corresponding to current densities of approximately 1.20, 1.33, and 1.47 A/mm

, were applied for 60 s during deformation, were utilized. The microstructure was characterized in accordance with ASTM E3 and ASTM E112 standards. Mechanical properties, including tensile and bending assessments, were evaluated following ASTM E8 and ASTM E290 standards. Microstructural analysis indicated that the application of electric current reduced θ AL-Cu precipitates and altered the microstructure. The highest tensile strength, 243.756 N/mnv

, were observed at 90 A. An increase in current resulted in diminished mechanical strengths. These findings confirm that variations in current substantially affect both microstructure and mechanical performance.
In this research, AZ91 magnesium alloy was subjected to solutionizing at 410 °C for different soaking times (4, 8, 16, and 24 h), and the microstructure evolution, phase change, and mechanical and corrosion properties were investigated. From the microstructural studies, it was clearly observed that the intermetallic ph...

In this study, the effect of heat treatment on the incremental hole flanging of 1.5 mm-thick AA6061 aluminum alloy sheets was experimentally investigated. Specimens were subjected to three conditions: annealed, solution treated, and artificially aged (T6). Flanging was performed using a five-stage forming strategy wi...

Centrifugally cast 35Cr45NiNb alloy has been widely employed in ethylene-cracking furnace tubes owing to its excellent carburization and creep resistance. However, the influence of microstructural degradation and temperature on its high-temperature tensile behavior remains poorly investigated. In this study, an acceler...

This study investigates microstructural and mechanical changes in automotive steel after a boriding process. Extended thermal exposure was analyzed to study the development of carbon diffusion zones (CDZs) and the resulting mechanical properties. Experimental results reveal the relationship between treatment conditions...

An investigation into the rate-dependent mechanical response and microstructural evolution of Ti-6Al-4V produced by additive manufacturing (AM) is presented. Three strain rate levels (1439 s−1, 2334 s−1, and 3302 s−1) were applied via Split Hopkinson Pressure Bar (SHPB) testing. The as-built alloy consists mainly of α...
