金属学报(英文版)

To study the growth of austenitic shells around the spheroidal graphite,color metallography has been employed.It is found that the shell is not a continuous layer of austenite,but a clus- ter of wedge-shaped crystals.Three types of shells have been observed.That may strongly af- fect the deteriorati...
