中文拼音 [xiāngbiànzēngrèn]
相變增韌
英文
transformation toughening-
On the other hand, when using p ( an - mma - as ) as polymer matrix, the gradient distribution of copper in pmgcf is raisonne, the crystal is smaller and compacter than the former, the flexibility of pmgcf increase as the concentration of mma in copolymer increase, the size of copper crystal increase as as the concentration of ita in copolymer increase
P （ an - mma - as ）為基體時金屬梯度分佈較合理，金屬晶體細小而且緻密，而且所制的pmgcf柔韌性較好，隨mma含量的增多而柔韌性增大，隨其中的as的含量的增大，所得的金屬晶體尺寸變化與p （ an ita ）相似，但變化的趨勢較緩慢。And even increaseed again a little. in this paper, the result of experiment has been discussed carefully useing transformation toughening and microcrack toughening mechanism
本文從zroz相變增韌和微裂紋增韌兩種機制出發對實驗結果進行了深入研究和討論。The principles have been successfully applied in those that zro2 stress inducement change phase and fiber, crystal beard or the second particles improve the toughness
上述兩類增韌原理分別在zro _ 2應力誘導的相變增韌和纖維、晶須或二相粒子的補強增韌中得到以成功的應用。The addition of y - zro2 improves the fracture toughness of pcd and the grinding ratio also increases with the y2o3 content increasing. the optimum comprehensive properties of pcd can be achieved as the y - zro2 powders contain 2mol % y2o3. aluminum addition in si3n4 or si3n4 bond pcbn can prevent y - zro2 powders from forming the nontransformable tetragonal phase
在si _ 3n _ 4及si _ 3n _ 4中介結合的pcbn中加入適量的al作為燒結助劑，可以避免不可相變的t相zro _ 2形成，使應力誘導相變增韌高溫高壓燒結的氮化硅系陶瓷成為可能。It was revealed that elastomer or filler had its strong point as modifier of pp. at the same matrix ligament thickness l, improvement of toughness by elastomer was obviously higher than that of caco3, while adding caco3 increased the modulus, hardness and heat deflection temperature of pp
0刀9匆m人指出用彈性體和無機剛性粒子作聚丙烯的增韌劑各有所長，在相同基體帶厚度l下，彈性體提高韌性的程度明顯高於c3co3 ， c3co3則使聚丙烯的模量、硬度和熱變形溫度等明顯提高。Klc of j3 is higher than j2 and j1 at different temperatures, and this shows the stronger ability of j3 to resist crack expanding. two probations have been tried to explore the reasons concerning the results above, one of which is by analyzing the compositions of the three pbxs above and shows that the stronger ability of j3 to resist crack expanding is probably mainly due to the use of bonder b2, and another is by using scanning electronic microscope sem to observe the fracture face morphologies of the specimens at different temperatures. the quantitative observations strongly support the laws of klc of pbxs changes with temperature is revealed as follows : a
測試了三種高聚物粘結炸藥在不同溫度下的平面應變斷裂韌度k _ （ ic ）值，得到了這三種炸藥的平面應變斷裂隨溫度的變化規律： a 、隨著溫度的增加，高聚物粘結炸藥的平面應變斷裂韌度降低； b 、在45以後j2的平面應變斷裂韌度降低最快，在60時已很差，比j1還低，可以認為j2在高溫下的抗裂紋擴展的能力比j1還差； c 、在不同溫度下， j3的平面應變斷裂韌度比j2和j1的均高，表現出相對較強的抗裂紋擴展能力。4. to improve the calculating accuracy, it was suggested to chang the ideal connection conditions between micro - crystalline phase and nano - crystalline phase and a midst zone should be built between them. and then the results calculated by the last step was viewed as the performance parameters of this zone, and the real connection conditions were closed
對代表單元體兩相連接界面的假設，進行嘗試性改進，即在增韌相與基體相之間增加一個界面過渡區域，同時將前步計算所得的代表單元形變性能作為界面過渡區域材料的性能，以近似模擬真實的界面連接情況，進而提高對整個代表單元體性能的計算精度。分享友人
