“The specimen was used for a series of thermal curves and was heated four times above the A3 transformation temperature; the total period above this temperature was four hours. The specimen was treated as for Fig. 13, with which this figure should be compared. Magnification, 500 diameters; etching, 2 percent alcoholic nitric acid“
