摘要：
Systematic nanohardness measurements on martensite, lower bainite, upper bainite, granular bainite and ferrite were carried out using nanoindentation technique. The variation of nanohardness among these ferritic phases is ascribed to the different capacity of strengthening factors in confining the geometrically necessary dislocation within indentation plastic zone. The large scatter of nanohardness distribution in lath martensite may be due to the uneven block boundary strengthening, inhomogeneous dislocation forest strengthening and the different extent of auto-tempering.
