Microstructural evolution of modified 9Cr-1Mo steel

Autor: C. R. Hills, Wendell B. Jones, D.H. Polonis

Publikováno v: Metallurgical Transactions A. 22:1049-1058

The tempering and subsequent annealing of modified 9Cr-lMo steel have been investigated to determine the influence of trace amounts of V and Nb on the sequence of precipitation processes and to identify the basis for the enhanced high-temperature str
