high-strength low-alloy (hsla) steels having low impact transition temperature are possible substitutes for costlier 2.5 and 3.5ni steels. the effects of solid solution strengthening, grain size and precipitation in ferrite on the strength and toughness of low-carbon steels and the special advantages of vanadium as an alloying element in hsla steels, are discussed. an investigation has been carried out with 1.5% manganese low-carbon steels containing vanadium in the range 0.12% ...
results of laboratory scale experiments carried out in nml are summarized. results of industrial scale trails on the production and controlled rolling of niobium steels, carried out in rourkela steel plant are discussed.
