Hello Inconel is Ni alloy and the etching of this is very difficult and that is why the measurement of grain size is difficult. The best etching agent known till now is through electretching using solution 60 ml ethanol, 35 ml distilled water, 20 ml glycerin, 10 ml lactic acid, 5 ml H3PO4, 2 g citriRead more
