This study presents a new mechanical tube cladding process named punch plastic deformation pipe cladding (PPDPC) based on local deformation by pressing a punch into the inner layer of the bimetal tube. To investigate the capability of the process, stainless steel tube (as the inner layer) is bonded to a carbon steel pipe (as the outer layer) to fabricate a bimetal pipe. Shear punch tests were u...

Bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. They made by welding resistive material to commonly available carbon steel pipes. The production of pipe bends with supercritical bend 0.7D, which part serpentine systems, is very complex and technologically demanding because often undesired cracks occur. To increase the ser...

We introduce a new adsorbent, bimetallic chitosan particle (BCP) that is successfully synthesized and applied to remove the orange II dye from wastewater. The effects of pH, BCP quantity, and contact time are initially verified on the basis of the percentage of orange II removed from the wastewater. Experimental data reveal that the Cu/Mg bimetal and chitosan have a synergistic effect on the ad...

Combining two different metals for the synthesis of a metal–organic framework (MOF) is smart strategy architecture new porous materials. Herein, bimetal–organic (bimetal–MOFs) based on Fe and Co was synthesized. Then, phosphorous acid tags were decorated bimetal–MOFs via postmodification method as acidic functionalized catalyst. This catalyst used pyrazolo[4,3-e]pyridine derivatives suitable dr...

An ultrasonic feature scan imaging system used for testing delamination flaw probably existing in the bimetal rotor clad layer was studied and developed. The bimetal rotor with nine column holes can be tested automatically. All the wave train of testing result will be saved in computer for post processing. There are various imaging modes including depth imaging and amplitude imaging, to find de...

Two-phase bimetal composites contain both grain boundaries and bi-phase interfaces between dissimilar crystals. In this work, we use a crystal plasticity finite element framework to explore the effects of grain boundary interactions on the plastic stability of bi-phase interfaces. We show that neighboring grain interactions do not significantly alter interface plastic stability during plane str...

We report here on an efficient one-step-impregnation method to synthesize crystalline mesoporous bimetal oxides (e.g. NiFe(2)O(4), CuFe(2)O(4), Cu/CeO(2)) using mesoporous silicas as hard templates under optimized mixing conditions. This new procedure enables a true replication of the mesostructure with high yield and phase purity, while retaining particle morphology of the template.
