Korean J. Met. Mater. 2019;57(1):60-66.   Published online 2018 Dec 14
DOI: https://doi.org/10.3365/KJMM.2019.57.1.60

Abstract
Both the mechanical properties and probability distribution of liquid phase sintered SiC (LPS-SiC) materials were investigated, based on a detailed analysis of their microstructures. In particular, the effect of the starting sizes of SiC particles on the characterization of LPS-SiC materials was evaluated. LPS-SiC materials were fabricated with a constant.....

Korean J. Met. Mater. 2018;56(6):413-422.   Published online 2018 Jun 4
DOI: https://doi.org/10.3365/KJMM.2018.56.6.413

Abstract
In the present study, the correlation of microstructural factors with yield ratio and uniform elongation was investigated in API X80 linepipe steels with different microstructures by varying thermomechanical control process conditions. The grain size and microstructure fraction of the API X80 linepipe steels were quantitatively measured by EBSD analysis and then..... More
