✦ Synopsis

New Method of Revealing Segregation in Steel Ingots. R.

tIADFIELD. (Iron and Steel inst. Journ., lxxxvi, 4o.)--The method consists in pouring a little molten copper on the top of the ingot soon after pouring. If the copper is added before solidification is complete it displaces the residual molten steel, but if added after complete solidification it fills up the cavities and shows the areas of segregation. This method seems to open up a valuable source of information on the rates of cooling, segregation, and liquation, and the present results indicate that the interior of an ingot remains hot for a much longer period than was previously thought, thus providing greater opportunities for segregation.
