中文摘要
这项工作将研究镍和铁-镍基高温合金的蠕变裂纹扩展,使用HTMI和DIC技术来获得与蠕变裂纹扩展过程相关的裂尖位移,在初始和稳态蠕变裂纹扩展区域。这项工作将对蠕变参数如K、J积分、Ct、C(T)和C*的有效性进行严格的评估。
英文摘要
The work will study creep crack growth in nickel and iron-nickel based superalloys using HTMI and DIC techniques to obtain crack tip displacements associated with creep crack growth process in the primary and the steady state creep crack growth regimes. The work will critically evaluate the validity of the creep parameters such as K, J-integral, Ct, C(t) and C*.
