摘要
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 high-temperature mechanical properties of Nb-Ti and niobium ferritic stainless steel after high temperature aging were studied by high-temperature tension test. The results show that the high-temperature yield strength of niobium ferritic stainless steel decrease rapidly with increase of aging times, while the high-temperature yield strength of Nb-Ti ferritic stainless steel is not obvious changes.
