裂紋敏感的
英文
crack-sensitive-
: 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。A reliability experiment of thermal aging was carried out for the two types of joints, scanning electron microscopy, energy dispersive x - ray spectrometer and micro x - ray diffractomer were adopted to investigate the interfacial evolution behavior of joints, and kinetics model of imc formation was established. the results show that imc growth follows the parabolic law as a function of aging time at certain aging temperature, imc growth is more sensitive to the aging temperature than the aging time, the activation energy of cu - al imc growth is 97. 1kj / mol and the major forming cu - al imc are cual2 and cu9al4, the activation energy of au - al imc growth is 40. 1kj / mol and the main au - al imc are au4al and au5al2, with au2al and aual at the interfacial periphery of joints, the rate of cu - al imc growth is about 1000 times slower than that of au - al imc, and kirkendall voids and cracks are easily appeared during thermal aging in gold ball bonds while voids and cracks are absent in copper ball bonds even after aging at 200 for 2900 hours and 250 for 169 hours
研究結果表明:金屬間化合物厚度與老化時間的關系符合拋物線法則，金屬間化合物的生長對老化溫度比老化時間更加敏感; cu - al金屬間化合物生長的激活能為97 . 1kj / mol ，老化后金屬間化合物呈層狀分佈，主要相為cual2和cu9al4 ; au - al金屬間化合物生長的激活能為40 . 1kj / mol ，主要相為au4al和au5al2 ，同時在界面周邊區域生成了au2al和aual ;老化過程中cu - al金屬間化合物生長速率比au - al金屬間化合物生長速率小103數量級;金絲球鍵合點200老化96小時出現了明顯的kirkendall空洞和裂紋，但銅絲球鍵合點200老化2900小時和250老化169小時都沒有形成空洞和裂紋。With the adoption of the rate - sensitive constitutive relationship, it is asymptotically investigated the propagating tip fields of antiplane mode iii crack under the condition of incompressibility, and the dynamics equations are obtained separately governing the stress and strain fields at the crack - tip
採用這種率敏感型本構關系，本文對不可壓縮條件下反平面型擴展裂紋的尖端場進行了漸近分析，分別求得了其裂紋尖端應力和應變場的動力學控制方程。Irrational drying conditions would lead to crack of rice, increasing sensitivity of breakage and lowering percentage of head rice during milling
