The escalating global demand for energy resources, particularly oil and natural gas,
underlines the critical need for enhancing the performance of pipeline infrastructure. This …

This study aims at correlating microstructure and Charpy impact properties in high-
toughness API X70 and X80 line-pipe steels. Three kinds of steels were fabricated by …

The correlation of microstructure and Charpy V-notch (CVN) impact properties of a high-
toughness API X70 pipeline steel was investigated in this study. Six kinds of steel were …

This paper establishes a framework of boundary conditions for implementing hydrogen
energy systems in ships, identifying what is feasible within maritime constraints. To support a …

A new ultrahigh strength niobium-microalloyed pipeline steel of yield strength∼ 700MPa
has been processed. The Charpy impact toughness at 0° C was 27J and tensile elongation …

In the present study, the simulated coarse-grained heat-affected zones (CGHAZs) of X90
pipeline steel were produced using a Gleeble 3500 simulator under different heat inputs …

The paper describes the microstructural constituents in a industrially processed Nb-
microalloyed pipeline steel having yield strength of∼ 620MPa. The microstructure of base …

In order to elucidate the relationship among microstructure, crystallographic orientation
characteristics and fracture behavior of pipeline steels at low temperature, three pipeline …
