3.
By way of studying thehardness of rail weld after flash welding or thermit welding, it is shown that bainite rail AB1 has higher.
通过对目前铁路大量使用的珠光体型热轧钢轨以及国产贝氏体AB1钢轨闪光焊及铝热焊接头硬度进行检验,其结果符合铁道部行业标准TB/T1632—2005钢轨焊接中的相关要求,对比了几种钢轨焊后硬度的不同,认为贝氏体钢轨整体硬度较高,正火后接头硬度不均匀性大幅改善,将较大地提高钢轨接头的耐磨性,减少因接头磨耗而导致过早下道的发生。

补充资料：铝热焊
用化学反应热作为热源的焊接方法。焊接时，预先把待焊两工件的端头固定在铸型内，然后把铝粉和氧化铁粉混合物（称铝热剂）放在坩埚内加热，使之发生还原放热反应，成为液态金属（铁）和熔渣(主要为Al2O3)，注入铸型。液态金属流入接头空隙，形成焊缝金属，熔渣则浮在表面上。为了调整熔液温度和焊缝金属化学成分，常在铝热剂中加入适量的添加剂和合金。图为钢轨的铝热焊。铝热焊具有设备简单、使用方便、不需要电源等特点，常用于钢轨、钢筋和其他大截面工件的焊接。
