高碳馬氏體
英文
high carbon martensite-
The results show that the solidification microstructure of high speed steel fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w ( wt ) contains of martensite, retained austenite structure, and mc, m6c, m2c carbides, and mc / m2c complex carbides by xrd, sem and metallographs. most of the mc carbides locate in the cell and other carbides distribute along the boundary of the cell
結果表明:經金相組織觀察、 x射線衍射和掃描電鏡分析, fe - 2 c - 4 v - 4 mo - 5 cr - x w合金系高速鋼凝固組織包含馬氏體基體、殘余奧氏體及各種類型的碳化物如mc型碳化物、 m _ 2c型碳化物、 m _ 6c型碳化物和mc m _ 2c類型復雜碳化物,大部分mc型碳化物分佈於晶粒內部,其它類型碳化物則沿晶界呈網狀分佈。The ultrasonic quenching of medium carbon alloy high strength steel 35crmnsi was conducted, using h66025t ultrasonic generator. the result showed the mertensite lath was fined obviously and the nucleation rate was improved. it proved the theory that the propagation of elastic wave in austenite can promote the nucleation of martensitic transformation
採用h66025t超聲波發生儀,對中碳合金高強度鋼35crmnsi進行超聲波淬火,發現馬氏體板條明顯細化,提高了馬氏體相變形核率,證實了彈性波在奧氏體中傳播促進馬氏體相變形核理論。Structural analysis of decomposition production of high carbon martensite after cryogenic treatment
高碳馬氏體深冷處理後分解產物的組織分析A solid solution of iron and up to1 percent of carbon, the chief constituent of hardened carbon tool steels
馬氏本,馬登斯體一種由鐵和高達百分之一的碳組成的溶液,是硬化碳工具鋼的主要成分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。Martensite transformation of an ultra - high carbon steel and grain size effect on sub - structure
超高碳鋼馬氏體相變及超細晶粒對亞結構的影響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
