Effect of TMCP Parameters on the Microstructure and Properties of the API X60 Pipeline Steels

Article Preview

Abstract:

Effects of technological parameters of thermo mechanical control process (TMCP) on microstructure and mechanical properties of the API X60 pipeline steels have been investigated. The parameters of TMCP for obtaining better mechanical properties are given. The experimental results show that the mixed microstructure mostly composed of polygonal ferrite, pearlite/bainite and martensite-austenite constituent (M-A) has the optimum strength and ductility.
