Thin strips of electrochemically deposited nanocrystalline nickel-iron with thicknesses of 320 or 330 µm are modified by defined grinding. Small changes in the cutting depth and the variation of the grinding process, up cut or down cut, result in di

The influence of notch manufacturing on the Charpy V-notch impact behaviour is undesirable and impairs the informative value of the V-notch impact tests. For this reason, specific investigations are carried out in the present part II to resolve more
