چکیده
The in-service cracks of the continuous casting machine roll are studied. The effects of high temperature fatigue crack growth were investigated for 25Kh1M1F steel, which is widely used for continuous casting rolls. In general, fatigue crack growth rates increased with increasing temperatures. At high crack growth rates, crack-tip plasticity was significant and propagation proceeded by ductile striation formation processes.
