孿晶 的英文怎麼說
中文拼音 [jīng]
孿晶
英文
compound twin-
Two area defects are twins and grain boundaries.
有兩種面積缺陷，即孿生和晶粒間界。Gross crystalline imperfections like twinning are apparent to the unaided eye.
粗的晶體不完整性，如孿生體可用肉眼看出。In electroplated metals, these defects are primarily dislocations, twins, and deposited foreign atoms or molecular groups.
對于電鍍的金屬來說，這些缺陷主要是位錯，孿晶和其沉積的異類，原子或分子基因。When ct20 alloy was tensioned at 20k, the main deformation mechanism in equiaxed microstructure was the slip of dislocations, and in bimodal microstructure the slip of dislocations and a small amount of twinning and in lamellar microstructure a large amount of twinning
Ct20合金20k拉伸變形時，等軸組織主要是位錯的滑移起主導作用，雙態組織除了位錯滑移外還有少量的變形孿晶產生，片狀組織中則能觀察到數量較多的孿晶。Microstructure evolution of twin lamellae with different lamellar size in rolling deformation at room temperature
孿晶片層結構在室溫軋制過程中的微觀結構演變It can be noticed that both r and t specimens show initial hardening and subsequent softening at the strain amplitude higher than 0. 8 % and cyclic softening from the beginning to fracture under strain amplitude less than 0. 8 % at room temperature, and the cyclic flow stress was always lower in r specimen than in t specimen at the same strain range
且在相同的應變幅下， t向試樣比r向試樣具有更高的循環流變應力。此外，對r向及t向試樣，低應變幅下呈現出循環軟化現象是因為晶粒旋轉導致循環軟化；而在高應變幅下發生循環硬化是由於孿晶作用的結果。The macroscopic defects such as twins, small - cracking, scattering particles, growth layer and cores are examined ; they are related with the temperature difference between gas and melt : the twins and small - cracking come out when the difference is large, the bubbles and scattering particles come out when that is small
觀察到了孿晶、裂隙、雲層、生長層和核心等宏觀缺陷，晶體的這些宏觀缺陷與氣- -液界面溫差有較大關系：溫差大容易造成孿晶、裂隙等缺陷；溫差小容易造成氣泡、散射顆粒等缺陷。The dfz might fragment and rotate as crack propagation
裂尖前方可能發生形變孿晶，裂紋沿孿晶界擴展。The role that twinning plays in the deformation of near a titanium alloy at cryogenic temperature can be divided into two parts, that is, direct part and indirect part
不同類型的形變孿晶對近a欽合金低溫下變形的作用分為直接作用和間接作用兩方面。Quite notable { 11 22 } twins with the appearance of strip piercing through lamellar colony were found in the tensile microstructure of ct20a alloy by tem analyzing, while no deformation twinning was found in the microstructure of alloy with high oeq
Ct20a合金低氧當量拉伸試樣的tem組織中有相當數量的{ 11幾}型孿晶存在，孿晶在形貌上表現為穿過幾個片的細條。高氧當量試樣中沒有觀察到變形孿晶的存在。Formed by the process of twinning. used of crystals
孿晶由孿晶過程形成的。用於晶體Macro - texture and micro - twins in free - standing diamond films
自支撐金剛石薄膜中的宏觀織構與微觀孿晶Coherent twin boundary
相干孿晶間界Corresponding to the amount rising of twins, the ductility at cryogenic temperature of ct20 alloy increased
與組織中變形孿晶增多相對應，合金20k的塑性增加。Defects such as extended dislocations, pile - ups of dislocation and grain boundaries ( twin boundaries ) were also investigated
塗層中存在擴展位錯、位錯塞積列、 （孿）晶界等晶體缺陷。Further ncrease in c content leads to lattice contraction, due to the solid solution in ubstitution mode, i. e. replacing si in the p structure
的b軸和c軸又幾乎相等，這都容易形成孿晶，使得界面情況變得復雜。The v abstract crack propagated through the deformation twins by step manner. the grainboundary repealed the dislocations emitted from the crack tip
首次發現工業純鈦裂紋擴展過程裂尖前方的微孿晶，微裂紋穿過微孿晶，呈臺階式擴展。Recently bulk tb - dy - fe single crystals have been obtained by magnetic levitation cold crucible without contamination in wuhan university of technology. these excellent single crystals, possessing a large displacement output under low magnetic field, build a foundation for the fabrication of the high precision micro - displacement actuators. the purpose of this research is to manufacture an advanced micro - displacement actuator with this high performance single crystal as the driving unit
常規的磁致伸縮型微位移致動器大多採用多晶或具有孿晶結構的磁致伸縮材料作為驅動單元，由於晶界和孿晶界對疇壁的移動具有阻礙作用，其低場下的位移輸出較小，調控精度受到很大影響。In this investigation, three types of twins were observed in the deformation microstructures of ct20 alloy at cryogenic temperature. that is, twins of { 11 2 ~ l }, { 10 t2 } and { li 22 } type. while only { 11 2 ~ 2 } type twin was found in ct20a alloy
