    摘要:

    用瞬间液相扩散连接方法,在650 ℃,2 Mpa压力下,真空保温2 h制备Ti-Al-304不锈钢复合板,并与550 ℃, 600 ℃ 真空热压扩散进行对比。采用SEM研究界面连接处的微观结构,选用EDS线扫描分析界面连接处的元素分布,利用XRD检测界面连接处的相组成。研究发现,瞬间液相扩散连接界面出现的位置与真空热压扩散不同,Al中间层可以起到阻止Fe元素向Ti基体中扩散形成Fe-Ti金属间脆性相的作用。该方法为研究钛钢复合板的制备提供了新思路。

    Abstract:

    This paper addresses the issue of transient liquid phase diffusion bonding of pure titanium to 304 stainless steel using aluminum interlayer, at the temperature of 650 ℃ for 2 h under 2 MPa load in vacuum. Then the result was compared with the case of 550 ℃ and 600 ℃. The microstructures, chemical compositions and reaction products of the transition joints were revealed in SEM, EDS and XRD, respectively. The experimental results has shown that, the position of the transient liquid phase diffusion bonding interface is different from that of the conventional thermal diffusion, and aluminum play a mid sole element to prevent iron diffusion to titanium master alloys forming brittle intermetallic phase Fe-Ti. This paper introduces a new technique of Ti-Al-304 stainless steel composite plate diffusion bonding.
