Fundamental phenomena governing heat transfer during rolling
Tập 24 Số 6 - Trang 1307-1320 - 1993
To quantify the effect of roll chilling on the thermal history of a slab during
hot rolling, tests were conducted at the Canada Center for Mineral and Energy
Technology (CANMET) and at the University of British Columbia (UBC). In these
tests, the surface and the interior temperatures of specimens were recorded
during rolling using a data acquisition system. The corresponding heat-transfer
coeffici...
Correlation of microstructure with mechanical properties of 300m steel
- 1977
300M steel was subjected to a wide range of quenched and tempered heat
treatments. The plane-strain fracture toughness and the tensile ultimate and
yield strengths were evaluated. Results indicate that substantial improvement in
toughness with no loss in strength can be accomplished in quenched and tempered
steel by austenitizing at 1255 K (1800°F) or higher. Low fracture toughness in
conventional...
