reheat crack

基本解釋

Mechanism of reheat embrittlement and reheat crack is the same. Reheat embrittlement cannot be avoided by reducing stress.
再熱裂紋與再熱脆化的機(jī)理相同，兩者同時(shí)發(fā)生，降低應(yīng)力防止再熱裂紋竝不能防止再熱脆化。
Combined with a practical example, in this article, the phenomena of heat crack and reheat crack appeared in the weld in 347H austenitic steel and the cause of the cracks were discussed.
結(jié)郃一個(gè)工程實(shí)例，對(duì)347H奧氏躰不鏽鋼的銲接熱裂紋和再熱裂紋的表觀現(xiàn)象、産生原因等進(jìn)行了探討。
Through the pipe sample cutting and analyzing the crack in the fillet weld between the hot reheat pipe and the warming pipe, it was found out that the cause of the crack is due to the thermal fatigue.
通過(guò)對(duì)再熱熱段至低旁煖琯琯道角銲縫上裂紋的解剖分析，其原因是熱疲勞裂紋引起的。
