hydrogen crack 中文意思是什麼
hydrogen crack
解釋
氫裂紋-
: 36 < kth < 37 mpa / m3 / 2, 42 < kih < 44mpa / m3 / 2, 51 < kc < 52 mpa / m3 / 2 through the sem fractography, it is know that the susceptibility to brittle failure at room temperature is more than below 100 ?. and the susceptibility to brittle failure increase with hydrogen increasing, under the sustained loading, ductile cracking appears. the quantity of brittle cracking is more with crack growth
T44mpa m 『 q ， sl lt52mpa in 』 」斷口分析表明，該合金充氫后其室溫時的氫脆敏感性大於100oc時的氫脆敏感性；且隨氫含量升高，氫脆敏感性增加：在恆載荷的作用下，該合金裂二紋開始擴展時顯示的是韌性起裂；隨裂紋增長，試樣脆性斷裂的比例增大。 -
