摘要

The crystallography, microstructure and mechanical property of as-quenched martensite of Fe-0.2C-Mn(-V) alloys of which the prior austenite grain sizes are 370-2 mu m were studied. The prior austenite grain, whose size is larger than 28 mu m, is divided by several packets. Those packets are subdivided by blocks containing sub-blocks, each of which corresponds to the Kurdjumov-Sachs variant. When the prior austenite grain size is about 2 mu m, one packet tends to grow predominantly. Each packet is divided by blocks containing sub-blocks.
