1.The fine structure is the determining factor in the formation of the physicomechanical properties of steel 06Kh14N6D2MBT in all stages of aging and overaging at temperatures of 100–550°.2.The ductile-brittle transition temperature Tcr determined atap=3 kgf-m/cm2 is far lower (-80°) for steel 06Kh14N6D2MBT than for pearlitic steel 12Kh2NMFA, both steels having the same fracture toughness at standard temperature.3.Intensive softening of steel 06Kh14N6D2MBT begins after heating above 450°, i.e., when the overaged condition is reached. |
