Feb 01, 2015nbsp018332The second group of FeTi ore deposits, with a magnetic signature drastically different from the former group, includes hemo-ilmenite-rich noritic rocks and massive hemo-ilmenite ores, containing no or minor multi-domain magnetite. Rocks from this group have high NRM and Q values, and moderate to high coercivities and susceptibilities.

Sep 29, 2014nbsp018332standard high carbon fe-mn is used when the steel is well oxidized low in c or when higher residual c contents are allowable. as maximum steel carbons become more restricted it is necessary to switch to the more costly low-or medium carbon fe-mn. mn content of steels. the normal mn content of the different type of steels is as follows.
One convenient way of illustrating quantitatively the effect of an alloying element on the -phase field of the fe-c system is to project on to the fe-c plane of the ternary system the -phase field boundaries for increasing concentration of a particular alloying element. this is illustrated in fig. 4 for ti, cr,
