摘要 相关文章 Metrics 全文: PDF(0 KB)   摘要: 在850、900和950℃不同轧制温度、1×10-2 Pa的高焊接真空度以及90%的总轧制压下率条件下, 用真空轧制复合技术制备无中间层的纯钛/钢/纯钛三层复合板, 研究了界面微观组织结构对界面结合性能的影响。结果表明, 在850℃轧制温度下, 复合界面层由0.5 μm厚的连续TiC薄层组成; 在900和950℃轧制温度下, 界面层由连续的TiC薄层和β-Ti相组成, 且随着轧制温度的提高界面层厚度逐渐增加。在不同轧制温度下在钢中靠近界面处均发现了铁素体带, 且随着轧制温度的提高铁素体带的宽度明显增大。在900℃轧制温度下得到了最高的界面剪切强度337 MPa, 且剪切断裂发生在TiC层和钢的界面上, 复合板弯曲到180°复合界面没有宏观和微观开裂, 显示了优异的界面结合性能。 Abstract： At different rolling temperatures of 850, 900 and 950℃ with constant vacuum level of 1×10-2 Pa and total rolling reduction ratio of 90%, the three-layer clad plates of pure Ti/high strength low alloy (HSLA) steel/pure Ti were successfully fabricated via vacuum rolling cladding (VRC) without the addition of interlayer, and the influence of interfacial microstructures on the bonding properties of the clad interface was investigated in detail. At a rolling temperature of 850℃, the clad interface only contained continuous TiC layer 0.5 μm in thickness, while at rolling temperatures of 900 and 950℃, the interface consisted of TiC and β-Ti. With increasing the rolling temperature, the interfacial thickness gradually increased. Under various rolling temperatures, an obvious ferrite band was detected in the HSLA steel side adjacent to the clad interface, and this width significantly increased as the rolling temperature increased. At a rolling temperature of 900℃, a maximum interfacial shear strength of 337 MPa with the fracture occurring at the interface between HSLA steel and TiC was achieved, and after 180° bending testing, no macro/micro-crack was generated at the clad interface, showing sound bonding properties of the clad plate through VRC.      ZTFLH:  分类号 TG142   基金资助:中央高校基本科研业务N090307003，N120407004和N110607001资助项目。 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y2013/V27/I6/569 [1] 李秋炎,岑启宏,蒋业华,周荣. 电脉冲频率对高硼中碳合金力学性能的影响*[J]. 材料研究学报, 2013, 27(6): 605-609.
