A low carbon Al-killed Ti-added steel was produced in Mobarakeh Steel Complex in Iran. Mechanical properties and microstructural characterizations of steel in the as-cast, hot-rolled, cold-rolled and annealed conditions are presented. Dilatometery tests were carried out to measure the finishing and annealing temperatures of steel. It was found that the addition of small amounts of Ti increas...

Micro-stamping process is one of the most cost-effective methods to manufacture metallic bipolar plates (BPPs). This research investigates the forming of titanium thin sheet as a potential candidate for BPPs in proton exchange membrane fuel cell (PEMFC). In this regard, the process was first simulated using finite element (FE) code Abaqus. Afterward, experimental tests were implemented and the ...

In order to investigate the formability of granular medium forming (GMF) based on Mohr–Coulomb constitutive model with tri-axial compression test and true stress–strain curves TA1 titanium alloy from uniaxial tensile tests, numerical simulation sheet deep drawing finite element method was performed, tests were also carried out. Simulation analysis results show that GMF process is suitable for s...

In this study, 22MnB5 sheet metals are reinforced using Directed Energy Deposition (DED) in order to investigate the quench-hardening behavior of additively manufactured 22MnB5. Therefore, hardness and element loss DED-material examined. When compared conventional materials, requires faster cooling rates achieve full martensite transformation. Titanium inhibits formation boron nitrides material...

Robotic incremental sheet forming has arisen a recent industrial interest, as more flexible and cost-effective solution to the process using rigid computer numerical control (CNC) machines. However, prediction of loads final geometry coupled an elastic modeling robot is essential optimize trajectory thus ensure geometrical accuracy part. Within this context, aim study investigate load in case s...

This paper summarizes our theoretical understanding of supernova events in a “back of the envelope” way. It is intended to aid in the recognition and understanding of those events which are not “standard”, and which may provide the most insight.

Single point incremental forming (SPIF) process has proven benefits in terms of formability, flexibility, and low cost as compared to conventional sheet forming, although it some issues such dimensional accuracy quality surface finish for materials. The SPIF is considered a potential method producing customised medical parts craniofacial implants using titanium sheet. This investigation aims an...

BACKGROUND Many implants are being used for the reconstruction of orbital wall fractures. The effect of the choice of implant for the reconstruction of an orbital wall fracture on the surgical outcome is under debate. The purpose of this article is to compare the outcomes of orbital wall reconstruction of small orbital wall fractures on the basis of the implants used. METHODS The authors cond...
