Abstract
The effect of electrohydraulic pulse treatment (EHPT) on the structure -sensitive characteristics (surface tension, kinematic viscosity) of 0 8GDNFL grade steel, grey iron and MO grade copper. The effect of EHPT on the rate of diffusion of elements in liquid copper was determined e xperimentally. EHPT was found to increase the surface tension of melts and simultaneously decrease their kinematic viscosity. A significant acceleration of diffusion of elements in liquid copper was observed. T hese changes were attributed to the reduction of chemical microinhomog eneity of metal melts as a result of destruction or reduction of size of microgroups (clusters).
