This paper aims to analyze the structure of Ti-25Ta-xZr system alloys (x = 0, 10, 20, 30, and 40% wt.) after melting hot-rolling by Rietveld's technique. The results confirm that zirconium acts as a β phase stabilizer (in which Ti-25Ta-40Zr alloy is fully in as-cast condition), increases lattice parameters phases, decreases c/a ratio α phase, consequently, elastic modulus values (86 72GPa) atom...

Final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. Measurement of residual stresses after straightening process is obligated by railmanufacturing standards. In the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...

Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...

Isothermal interrupted hot compression tests of 5754 aluminum were conducted on a Gleeble-3500 thermo-mechanical simulator at temperatures of 350 °C and 450 °C, and strain rates of 0.1 s−1 and 1 s−1. To investigate the metadynamic recrystallization behavior, a range of inter-pass delay times (5–60 s) was employed. These tests simulated flat rolling to investigate how softening behaviors respond...

Slivers on the surface of rolled plates, which are serious defects for interstitial-free (IF) steel, occur mainly as a result inclusions in continuous casting (CC) slabs. It is, therefore, important to study CC slabs terms their migration towards during hot rolling. To investigate inclusion rolling ultralow carbon 3D numerical model was constructed using finite element method. The positions lay...

Development of submicrocrystalline structure in biomedical alloy such as Ti-13Nb-13Zr (in wt%) through warm-rolling process has been found to enhance mechanical properties compared to conventional thermomechanical processing routes including hot-rolling process. The present study investigated the tribological and corrosion behaviors of warm-rolled (WR) and hot-rolled Ti-13Nb-13Zr alloys which h...

A ring-shaped Mg–8.5Gd–4Y–1Zn–0.4Zr (wt%) alloy was manufactured via centrifugal casting and ring-rolling process. The effects of accumulative reduction amount on the microstructure, texture, tensile properties were investigated. results indicate that microstructure cast consists equiaxed grains network-like eutectic structure present at grain boundaries. ring-rolled exhibits a characteristic b...
