Can I read The effect of hold-time on fatigue crack growth behaviors of WASPALOY alloy at elevated temperature on EtoBox?
The effect of hold-time on fatigue crack growth behaviors of WASPALOY alloy at elevated temperature by Xingbo Liu; Bruce Kang; Keh-Minn Chang is a Engineering article available to read on EtoBox.
What is The effect of hold-time on fatigue crack growth behaviors of WASPALOY alloy at elevated temperature about?
The effect of hold-time on fatigue crack growth behaviors of WASPALOY alloy was investigated. It was found that the role of hold-time depends on the competition between the harmful environmental effect and the beneficial effect of creep. If temperature is not higher than 705 8C, fatigue crack growth rate of WASPALOY alloy increases with hold-time. On the contrary, hold-time plays a beneficial role on steady state fatigue crack growth of WASPALOY alloy at 760 8C and lower stress intensity factor. The beneficial effect of hold-time was attributed to the creep caused stress relaxation during the hold-time. However, accumulated creep damages cause to cavity nucleation and growth at the grain boundaries, and then accelerate fatigue crack growth. Hold-time plays a harmful role during the final stage of fatigue crack growth.
Who reads The effect of hold-time on fatigue crack growth behaviors of WASPALOY alloy at elevated temperature?
It is typically read by researchers, students, and practitioners in Engineering.
