中文拼音 [mǎshìtǐxíngchéng]
馬氏體形成
英文
martensite formation-
The crystal structure of the martensite as quenching state, the variation of the structure of the martensite during non - isothermal aging in the martensite and parent state, under successive deformation condition and under thermal cycling condition in the cu - based shape memory alloys are studied by the x - ray diffraction
摘要運用x -射線衍射分析技術研究了不同成分銅基形狀記憶合金淬火態馬氏體結構、馬氏體狀態非等溫時效過程中結構的變化規律、母相狀態時效和連續變形過程中馬氏體及母相結構的變化規律以及熱循環過程中馬氏體結構的變化情況。Consequently martensite will form in the welds and heat affected zone ( haz ) requiring proper and precise pwht procedures
因此在焊接部位和熱影響區域（ haz ）形成馬氏體就需要正確的精密的pwht工序。Strengthening mechanism of ion nitriding is different from surface quenching and cementation, which makes surface strengthen by quenching to get martensite. ionic nitriding is the way to make materials strengthe n, which result from the steady compound formed on the surface of the metal. there is no need for quenching after treatment
離子滲氮的強化機理不同於表面淬火，滲碳等表面熱處理方法，這些方法必須進行淬火得到馬氏體使表面強化，而離子滲氮是在金屬表面形成穩定化合物而使材料強化，處理后不須淬火。The network carbide and acicular martensites that existed in the microstructure of the root grooves of the spline due to improper carburating and quenching process of the shafts, led to the initiation and propagation of the intergranular microcracks and were the main reason that caused the early fracture of the shafts
由於滲碳淬火工藝不當，在二軸花鍵槽根部的組織中產生了網狀破化物和粗大的針狀馬氏體，在外力作用下形成沿晶顯微裂紋並擴展，是導致二軸疲勞斷裂的主要原因。The reason is that the elastic energy increases the nucleation work while the formation of primary martensite can excite the release of elastic energy in austenite to promote the formation of after martensite and intensify the tendency towards homogeneous nucleation
其原因是彈性能的存在增大了初生馬氏體的形成功，而初生馬氏體的形成則會激發奧氏體內彈性能的釋放，彈性能的釋放可促進繼生馬氏體形成，並增大其均勻形核傾向。The result showed that plastic deformation during pre - strain played an restrained role on the growth of martensite ( especially in the direction of lath width ) and increase the nucleation rate indirectly ; the elastic energy induced by plastic deformation restrain the transformation of primary martensite but accelerate the transformation of after martensite
實驗結果表明：預應變過程中造成的塑性變形對馬氏體生長（尤其是寬度方向）有約束作用，起間接提高馬氏體形核率的作用，所儲備的彈性應變能對初生馬氏體的轉變有抑制作用，但對繼生馬氏體的轉變卻有促進作用。Martensite formation during mechanical alloying of fe - ni and martensitic transformation
機械合金化過程中馬氏體的形成及相變The effect of plastic deformation and elastic strain energy induced by pre - strain on the nucleation of martensitic transformation of low alloy ultra - strength steel sosimncrmov had been studied by pre - strain quenching in austenite state. the control over deformation magnitude and deformation temperate as well as loading pattern was performed to adjust the storage of elastic strain energy in steel before martensitic transformation, using the type of geeble - 1500 thermal analogue test machine
使用gleeble - 1500型熱模擬機，對低合金超高強度鋼30simncrmov實施奧氏體預應變淬火處理，通過控制形變量、形變溫度和加載方式，調整鋼中馬氏體相變前的彈性應變能儲備，研究了預應變所造成的塑性變形與彈性應變能對馬氏體相變的影響。The results show that, when the hardfacing process is not appropriate, the thick martensite structure with high carbon content will form in the overheat region of heat affected zone, and the high residual stress occurred, which are the primary causes resulting in crack
結果表明，堆焊工藝制定不當，熱影響區的過熱區形成高碳粗大馬氏體組織及保留了較大的焊接應力，是導致堆焊層開裂的主要原因。By differential scanning calorimetry ( dsc ), respectively. without any supplementary method, a ti - rich alloy target ( ti - 48at % ni ) were used to enrich ti content in films during sputtering. as the first step, tini thin film is deposited on a glass substrate by sputtering, and annealed at 600
採用絲材冷軋法，制備了75 m 、 90 m兩種厚度的tini形狀記憶薄膜，示差掃描量熱（ dsc ）法測得其馬氏體逆相變峰值溫度分別為35 、 109 ，在濺射工藝中，採用富ti的tini合金靶（ ti - 48at ni ）而不是其它成分補償措施，來增加tini薄膜中的ti含量。Abstract : the microstructure of as - cast high cr injection micro - alloying martensitic cast iron and the substructure of martensite in it have been observed under sem and tem. the alloying element distribution related to phase formation, as well as the various types of branch and distortion of carbide in the martensitic cast iron have been explored by using x - ray diffraction and electron probe analysis
文摘:應用掃描電鏡和透射電鏡研究了噴射微合金化的鑄態馬氏體高鉻鑄鐵顯微組織及馬氏體的亞結構，並藉助x射線衍射與電子探針分析探討了合金元素的分佈與相形成的關系，以及碳化物的不同形式分枝與畸變。分享友人
