THE EUTECTOID TRANSITION POINT OF CARBON STEELS. 



201 



19. Confirmatory Experiments in Weak Fields. 



Some points of interest are shown in further experiments upon the eutectoid steel 

 represented in figs. 12 and 13 and already referred to in 17. 



675 



775 C 



The field intensity was now only 25 C.G.S. units. The first figure shows the effects 

 of two interruptions during heating from about 680 to about 800 C. The sequence 

 will be obvious from the lettering. Thus heating was first interrupted at B, their 

 cooling was interrupted at C, and so on, alphabetically, to F (about 800 C.).
