Vv. Kalmykov et En. Shilovskaya, EFFECT OF THERMOMECHANICAL STRENGTHENING ON STRUCTURE FORMATION AND PROPERTIES OF STEELS HEATED TO SUBCRITICAL TEMPERATURE-RANGE, Russian metallurgy. Metally, (2), 1993, pp. 95-97
The structure formation and properties of 20GS and 10GS2 reinforcing s
teels on tempering in the subcritical temperature range (700 degrees C
, 1 h) after thermal strengthening from rolling or furnace heating tem
peratures as studied. it is shown that the high-temperature thermomech
anical strengthening (HTTMS) effect occurring when the steel is therma
lly strengthened from rolling temperatures facilitates the alpha-->gam
ma transformation on tempering and that alloying low carbon steel with
up to 2% Si hinders this transformation in both thermal strengthening
procedures. The nature and consequences of these effects are discusse
