Additive manufacturing is a rapidly expanding technology in many scientific fields like tissue engineering. One of the most essential duties of tissue engineering scaffolds is to provide sufficient mechanical strength for the injured bone tissue. Scaffold architecture plays a significant role in its mechanical properties. Here, six delicate different geometry computer-aided design models with identical porosity were designed. The sets of 0/90, 0/45/135/90, 0/60/120, and their shifted models as t...

In this research, hypereutectoid Si–Mn TRIP steel was prepared via casting method followed by thermomechanical processing and different heat treatments. Subsequently, fracture behavior and mechanical properties of the prepared steel were investigated. The time–temperature–transformation curves of the specimens were predicted by a simulation software. Their mechanical properties were studied through tensile, hardness, and impact tests. The microstructure and fracture behavior of the specimens wer...

Abstract Failure analysis of a 17th stage blade of a steam turbine fractured in the vicinity of the lacing hole is discussed in this study. For this purpose, visual inspection, chemical and structural analyses, hardness and uniaxial tensile tests, macro and micro-fractography, fracture mechanics calculations, as well as computer simulations have been carried out. According to the results of the hardness and tensile tests and a comparison with the properties of AISI 410 martensitic stainless stee...

ABSTRACTReduction of nickel oxide (NiO) by hydrogen gas is an affordable and simple way in comparison with the other chemical methods to produce and retrieve the pure nickel powder. Properties of the reduced Ni powder are dependent on many parameters such as the temperature, holding time, and hydrogen gas flow. The main reported mechanism of hydrogen reduction contains the decomposition of the oxide into gas-state phases and then condensation of the product supersaturated vapor. In the present w...
