    摘要:

    用瞬間液相擴(kuò)散連接方法,在650 ℃,2 Mpa壓力下,真空保溫2 h制備Ti-Al-304不銹鋼復(fù)合板,并與550 ℃, 600 ℃ 真空熱壓擴(kuò)散進(jìn)行對比。采用SEM研究界面連接處的微觀結(jié)構(gòu),選用EDS線掃描分析界面連接處的元素分布,利用XRD檢測界面連接處的相組成。研究發(fā)現(xiàn),瞬間液相擴(kuò)散連接界面出現(xiàn)的位置與真空熱壓擴(kuò)散不同,Al中間層可以起到阻止Fe元素向Ti基體中擴(kuò)散形成Fe-Ti金屬間脆性相的作用。該方法為研究鈦鋼復(fù)合板的制備提供了新思路。

    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.
