熱影響區裂紋
英文
beat-affected zone crack-
The microfissuring behaviors in the heat - affected zone ( haz ) of electron beam ( eb ) welded nickel - based superalloy gh 4133 have been studied by using analytical scanning electron microscopy ( sem )
摘要利用金相分析和掃描電鏡對鎳基高溫合金電子束焊接熱影響區微裂紋行為進行了分析。This segregation behavior of sn accords with the mechanism of non - equilibrium segregation. it can be obtained through the theoretical calculations that the critical time of sn non - equilibrium segregation is 124 seconds at 750 and the critical cooling rate is 8 / s when cooling from 1320. it is suggested that controlling the cooling rate during continuous casting to avoid the critical cooling rate ( 8 / s ) and avoiding high stress near the trough temperature ( 750 ) may control the form
通過研究殘留元素sn的偏聚機制及其對o . 15wt . % c鋼熱塑性的影響,對試驗鋼進行脆性預測:建議在該鋼的連鑄過程中彎道矯直溫度盡量避開塑性谷底溫度750 ,二冷區的冷速盡量避開臨界冷卻速率8 / s ,從而可以減少該低碳鋼連鑄坯表面裂紋和橫向裂紋,提高其成材率。Minimal the tendency of microcracks can be obtained by improving the shape of weld pool and enhancing the welding energy input
通過改善焊縫成形和提高焊接線能量有助於減小兩類熱影響區微裂紋傾向。It is observed that considerable liquation microcracks and some other microffissures called solid - state microcrack initiate in the regions nearby the fusion line and propagate across the grain boundary
研究發現,熔合線附近的熱影響區產生大量液化裂紋和沿晶擴展的固相裂紋。分享友人
