而铌元素的加入增大了过冷奥氏体的稳定性，相变点温度降低，并且推迟珠光体的转变。
But Nb adding increases the under-heating austenite stability, reduces the temperature of phase transformation point and postpones the transformation of pearlite.
本发明的方法可良好地实现含稳定化元素的奥氏体不锈钢厚壁管道的焊接及热处理施工。
The method can well realize the construction of welding and heat treatment of the austenitic stainless steel thick-wall pipeline containing stabilizing elements.
同时稀土与低熔点合金元素的加入，是强烈促进珠光体的元素，具有稳定珠光体的作用，提高了奥氏体化温度；
The austenitizing temperature was raised by addition of RE and low melting-point alloy which were the elements of strongly promoting and stabilizing the pearlite.
研究结果表明：不锈钢丝合金元素对316 l奥氏体的稳定性有显著影响。
The experimental results show that alloying element content influence the austenitic stability of stainless steel. The lower the element content, the poorer the austenitic stability.
