对含Nb-Ti和铌铁素体不锈钢进行高温时效和固溶处理,通过高温拉伸试验研究其高温力学性能变化。结果表明,随着时效时间的延长,铌钢的高温屈服强度下降很快,而Nb-Ti钢的高温屈服强度并没发生较大变化。
The Nb-Ti and niobium ferritic stainless steels were subjected to high temperature aging and solution treatment. The high-temperature tensile tests were carried out to study the changes of high-temperature mechanical properties. The results show that with the aging time, the high temperature yield strength of niobium steel decreases rapidly, while the high temperature yield strength of Nb-Ti steel does not change significantly.
