: 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。 -
Except for a small length of web at the first fracture location, none of the cracks exhibited a brittle fracture mode of crack propagation.

It was found that the cracks can penetrate the interphase and the fiber rapidly when the interphase is thin, which causes the low flexural strength and fracture toughness, as well as the composites " brittle fracture. while the interphase is thick, multiple toughening mechanisms such as the crack deflection and matrix cracking can be activated, which cause the composites " flexural strength and fracture toughness is high and the composites " non - brittle fracture
當界面相較薄時，基體裂紋能夠迅速穿過界面相和纖維，復合材料具有較低的彎曲強度和斷裂韌性，表現為脆性斷裂模式；當界面相較厚時，復合材料能產生裂紋偏轉、基體開裂等多種增韌方式，具有較高的彎曲強度和斷裂韌性，呈韌性斷裂模式。 -
