Continuous welded turnouts are important for CWR track through the railway station. According to equivalent resistance and non-linear theories and the principle of force diagram, a new method of theoretical calculation for continuous welded turnouts was developed. The continuous welded turnouts designed and installed according to the new theory behaved fairly well. The data collected on sites b...
Abstract The processes of rolling and annealing explosively welded multi-layered plates significantly affect the functional properties composite. In current research, fifteen-layered composite were fabricated using a single-shot explosive welding technique. composites then rolled up to 72% reduce layer thickness, followed by at 625 °C for varying times 100 h. Microstructure evolution chemical c...
analysis of die less explosive forming of bimetallic circular plates using “energy conservation law”
die less explosive forming of circular plates is one of the most useful methods in the industries especially chemical applications. manufacturing of large vessel's head, multilayer rings and some parts of heat exchangers are the example of applying this method. many theoretical and experimental researches about examining the explosive forming of simple and single layer plate have been done...
The most effective method to reduce CO2 gas emission from the steam power plant is to improve its performance by elevating the steam temperature to more than 700 ◦C. For this, it is necessary to develop applicable materials at high temperatures. Ni-based Alloy 617 and 12Cr steel are used in steam power plants, due to their remarkable mechanical properties, high corrosion resistance, and creep s...
OBJECTIVE We investigated electroencephalographic (EEG) correlates of moderate intermittent explosive disorder (mIED), which is characterized by uncontrollable, impulsive attacks that either manifest in aggressive outbursts of temper, or in implosive, auto-aggressive behaviour. METHODS In two Experiments, EEG data were recorded during rest conditions, and while subjects were presented with au...
In this research, the effect of standoff distance and explosive material thickness on metallurgical features of explosive welding connection of copper to 304 stainless steel has been investigated. Experimental analysis were performed using optical microscopy, scanning electron microscopy, microhardness test and tensile shear strength test. The results indicated that due to severe plastic deform...
