Furen XIAO , Mingchun ZHAO , Yiyin SHAN , Bo LIAO , Ke YANG

材料科学技术（英文）

Acicular ferrite microstructure was achieved for an ultralow carbon pipeline steel through the improved thermomechanical control process (TMCP), which was based on the transformation process of deformed austenite of steel. Compared with commercial pipeline steels, the experimental ultralow carbon pi...

Influence of hot deformation and cooling conditions on the microstructures of low carbon microalloyed steels

Jinbo QU , Yiyin SHAN , Mingchun ZHAO , Ke YANG

材料科学技术（英文）

The transformation behaviours and microstructural characteristics of three low carbon microalloyed steels were investigated. In particular, the effects of deformation and cooling conditions were studied by means of compression tests. It was found that at higher cooling rate (45℃/s), the transformati...

Noncollinear magnetic ground state of PrFeAsO

Europhysics Letters

Noncollinear magnetic investigations of the ground state in PrFeAsO have been performed by the density-functional theory. We calculated the total energy and made structure optimization, and the electronic density of states of PrFeAsO was analyzed. There are three different magnetic structures in PrF...
