Experimental and numerical study on the explosive welding of niobium-steel

The aim of this work is to study the method explosive welding produce niobium-steel composite plate, which used in nuclear industry equipment material manufacturing. parameters were determined by weldability window, and numerical simulation was predict wave shape interface. morphology interface observed scanning electron microscope. Measured element distribution near experimental samples investigated using mechanical tests. results show that optimized theory can be obtain a plate with better quality. It proved quality observing testing properties; it seen melting zone composed niobium steel composition analysis instrument. consistent results, shows changes temperature, strain, stress during process.
