[20] Hadfield's invention was the first alloy of steel to demonstrate considerable differences in properties compared to carbon steel. [ 13 ] In the modern age, it is known that manganese inhibits the transformation of the malleable austenite phase into hard brittle martensite that takes place for normal steels when they are quenched in the ...
