| Abstract: | The wear resistance under a high impact energy of 6Mn2Cr metastable austenitic steel is remarkable increased by the low temperature aging. The results of Mossbauer spectroscopy show that C and Me-free martensite in induced in the worn surface of the age-treated specimens. However, there exist the induced martensite without and with C and Me in the worn surface of the water-quenched specimens. The microstructure in the worn surface of the age-treated specimens is C and Me-containing austenite, and C and Me-free martensite obtain a high and stable toughness during further wearing, thus leads to a high wear resistance. |
