摘要：
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 degrees C after austenitizing at 1280 degrees C following by isothermal retention in the area of high resistance of the undercooled austenite(500-650 degrees C). 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 degrees C and 650 degrees C on the characteristics of the austenite-to-bainite transformation in steel HS18-0-1 is established.
