Hi,
i am working with a low alloy steel. When it has been quenched and hot
coiled into a spring then tempered i am seeing straw coloured bands in
the microstructure. At higher magnification they appear white,
possibily ferrite ? I'm guessing this is something to do with
segregation. Can anybody help ?
Does anybody know what effect this would have on the fatigue
properties ?
thanks
