Microstructural characteristics of 35SiMnCrMoV steel transformed at medium and low temperature were observed. The experimental results showed that three kinds of structures i.e. law bainite, bainite/martensite and martensite have different strength. However, these structures all have rather good toughness. A mixed structure of bainite/martensite as a result of isothermal qucnching at 330℃ has better combinative properties which is due to randomly distributed small bundles of lath martensites...

Microstructural characteristics of 35SiMnCrMoV steel transformed at medium and low temperature were observed. The experimental results showed that three kinds of structures i.e. law bainite, bainite/martensite and martensite have different strength. However, these structures all have rather good toughness. A mixed structure of bainite/martensite as a result of isothermal qucnching at 330℃ has better combinative properties which is due to randomly distributed small bundles of lath martensites and considerable amount of retained austensites at lathboundaries and homogeneously distributed carbide within the bainitic ferrite. Therefore, choosing correct isothermally quenched processes are an effective way to improve strength and toughness of 35SiMnCrMoV steel.

观察了35SiMnCrMoV钢中、低等温转变组织的显微特征。实验结果表明下贝氏体、下贝氏体/马氏体和马氏体三种组织的强度不同,但均有相当好的韧性。330℃等温下的下贝氏体/马氏体混合组织具有较佳的综合性能,这是由于它有各向分布、小尺寸的板条马氏体束,而且板条边界上有较多的残余奥氏体存在,以及在贝氏体的铁素体内碳化物均匀分布。因此选用合适的等温淬火工艺是提高35SiMnCrMoV钢强度韧性的一条有效途径。

无论是蒸发沉积、离子溅射沉积、离子束沉积还是其它类型的沉积,所沉积的薄膜的微观结构、薄膜与衬底间的界面性质与沉积粒子的性质、能量等因素密切相关。本工作利用俄歇电子能谱仪(AES)所测得的俄歇信号时间曲线(AST),俄歇的价带电子跃迁(AVV)图以及俄歇信号相对强度与沉积厚度的相互关系曲线研究和分析银蒸发束(原子、分子、原子团束)、低能(22eV)和较高能(320eV)Ag~+束在室温Si(111)衬底表面上的沉积过程和可能发生的界面反应。实验结果表明:(1) 蒸发沉积时,银在衬底表面上首先是形成均匀的原子层,接着聚集成为小岛,随后才形成为完整的薄膜;(2) 低能(22eV)Ag~+束沉积时,薄膜为均匀的层状结构,也就是说,薄膜的生长方式是以层层生长方式进行的,衬底与薄膜间的界面在所讨论的1nm范围内是未反应的;(3) 高能(320eV)Ag~+束沉积时,在沉积的初始阶段,界面上会发生严重的混杂效应,以致于形成一种银和硅的混合相结构,在此之后,界面混杂才慢慢停止,形成完整的Ag薄膜。

A new broad band laser quenching process was developed for surface hardening of the large module gear. Parameters of the process are optimized to make the gears possess a core hardness of HRC 30~35, a surface hardness of HRC 55-60,and a hardened layer, 1.2~1.4mm in depth. A mixed structure of martensite and retained austenite are obtained in this surface layer. The residual compressive stresses existing in the surface layer was measured to be 267~425 MPa.
