| Abstract: | It is usually difficult to obtain a good result in showing the low-carbon-or size-uneven austenite grains when a 15% hydrochloric-alcohol solution is used as the etchant,which inevitably affects the grain size measurement of austenite.A new etching reagent composed of hydrochloric acid solution containing 1% FeCl3 was therefore employed to etch the austenite grains,and a satisfactory result obtained. |
