This work investigated the effects o f the metallurgical parameters on th e forming of adiabatic shear bands(ASBs )in some different state metals under the same explosiv e cladding process by observing microstructures and measuring microhardness.The results indicated that the shape,size and quantity of ASBs a re affected by the factors of pre-deformed degree,crystal structure,ph ase states etc.The mi-cro-hardness of ASB is higher than th at of the matrix.
