The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。
