Sažetak
The investigation on the structure formation in the bainitic area for high-speed steel HS18-0-1 is performed. The austempering is carried out at 270 °С after austenitizing at 1280 °С following by isothermal retention in the area of high resistance of the undercooled austenite(500÷650°С). The kinetic of the bainitic transformation, the obtained structure by means of optical metallography (OM), transmission electron microscope (TEM), X-ray analysis and hardness measurement by Rockwell method are studied. The influence of the preliminary destabilisation of the undercooled austenite at 560 °C and 650 °C on the characteristics of the austenite-to-bainitе transformation in steel HS18-0-1 is established.
