WHITE IRON ALLOYED
|Abstract:||A study ties been of tho effect of heat-treatrnent on ha ness# microtructure wd corrosion behaviour ( in 5'6 Noci solution) in a Cr white iro alloyed with 6"'/. to and 1 T, Cu. Heat-treatments comprised of aircooling or oil quenching from 900, 950, 4000 and 1050°C ftor bolding at cch of these tez er tutus,, for 4,6,6 and. 10 hours# respectivc1y* Corrosion studies were varied out on oil quenched s plos, scwe of -..,i' i h were sass relic red by holding them for 0,5 hour at 60OPC followed by .~* o ing oz furnace cooling, I t is observed that niicrostn1Cttirec with atrneitie matrix are mot favourable froi the Point of v ew Zf corn) l on rest steno .
