In this work, the hot forging behavior of a dual phase stainless steel in temperature range 850–1250 °C was investigated. The study revealed occurrence significant cracking phenomenon for processing temperatures below 950 that attributed to combined effect intermetallic precipitation and severe deformation. EBSD examination highlighted continuous dynamic recrystallization both ferrite austenite...

We investigated film thickness effects of sulfuric acid anodized aluminum when galvanically coupled with carbon fiber reinforced plastic(CFRP). The CFRP was electrically to alloys 1050, 5052, 6061, and 7075 in 3.5 wt.% NaCl solution at 35 ℃. Galvanic current passing from the 1050 6061 decreased as anodic oxide thickened. For galvanic between 5052 CFRP, elapsed time until corrosion density value...
This is a numerical study to investigate the behavior of novel stiffened angle shear connectors embedded in solid concrete slabs at both ambient and elevated temperatures. An advanced nonlinear finite element model developed validated with available experimental work by Nouri, K., et al. 2021. Additionally, parametric studies are performed evaluate variations strength connector’s dimensions. Th...
In the present work, hot tensile behavior of Haynes 25 Co-base alloy was investigated in the temperature range of 950-1200 ˚C and 0.1 s-1. Thermodynamic calculations showed that M23C6 and M6C carbides were stable below 1000 ˚C and above 1050 ˚C, respectively. Stress-strain curves also indicated an unusual trend of strain fracture. It was observed that with increasing temperature from 950 to 105...
A 1050-O aluminum plate and a low carbon steel (SPCC) were seam welded by magnetic pulse welding (MPW). Experimental numerical analysis methods combined to investigate the wavy interface formation local melting phenomena at Al/Fe joint interface. The metallographic observation results showed that presents trigger-like wave shape with two types of intermediate layers intermittently formed Collis...

PURPOSE To assess the application of optical frequency domain imaging (OFDI) at 1050 nm for the detection of choroidal neovascularization (CNV) in age-related macular degeneration (AMD) and its response to treatment. Three patients presenting with blurred vision and exudative AMD were imaged before and after anti-VEGF treatment with ranibizumab. METHODS The patients were imaged with OFDI, a s...
