利用光学显微镜、扫描电子显微镜研究了不同温度下钛层对钛钢爆炸复合板钢侧组织转变的影响。结果表明:有钛层时,钢侧结合界面上会形成脱碳层。当850℃及以下温度加热时,在波头的漩涡处产生粗大的铁素体晶粒,而在950℃保温时,在波峰处产生粗大的铁素体。剥离钛层时,只在波头的漩涡处产生铁素体区,随着温度的升高,铁素体区减小。产生这种现象的主要原因是钛层的存在,碳元素向结合界面扩散形成TiC,在结合界面附近形成铁素体区。
Using optical microscope and scanning electron microscope, the effect of Ti layer on the microstructure of the steel side of the titanium steel explosion clad plate under different temperatures was studied. The results show that there is a decarburized layer on the steel-side interface when there is titanium layer. When heated at a temperature of 850 ° C or below, coarse ferrite grains are formed in the whirlpool of the wave crest, and coarse ferrite is generated at the crest when the temperature is kept at 950 ° C. When the titanium layer is peeled off, the ferrite region is generated only in the whirlpool of the wave head, and the ferrite region decreases as the temperature increases. The main reason for this phenomenon is the presence of a titanium layer, which diffuses to the bonding interface to form TiC and forms a ferrite region near the bonding interface.
