THE INFLUENCE OF MN STEELS AGEING ON HEAT TRANSFER PHENOMENA

Popis výsledku v původním jazyce

Thermophysical properties under investigation ? thermal diffusivity, specific heat capacity, thermal conductivity ? play an important role for designing material under thermal stress. The original austenitic manganese steel, containing approximately 1.2wt.% C and 12 wt.% Mn, was invented by Sir Robert Hadfield in 1882. Hadfield´s steel was unique in that it combined high toughness and ductility with high work-hardening capacity and, usually, good resistance to wear. Thermophysical properties have beenmeasured by lumped capacitance method. We have measured three different materials with markings 1023, 1026, 1028. Maximal content of Mn and C was 27 and 0.5 wt.%. Material 1026 had the highest content of C 0.5 wt.%, Ni 1 wt.% and showed the highest specific heat capacity and the highest thermal diffusivity in non-aged state. From results of thermophysical properties after ageing, it can be seen the increase of thermal diffusivity up to 20 percent, thermal conductivity up to 15 percent an
