Korean J. Met. Mater. 2021;59(9):652-663. Published online 2021 Aug 4 DOI: https://doi.org/10.3365/KJMM.2021.59.9.652
Abstract
A cooling channel with an optimized design provides not only high throughput with gravity die casting, but also guarantees product quality. A conformal cooling channel (CC) whose structure follows the shapes or surfaces of the mold cavity has attracted great attention in the die casting industry, because it allows rapid..... More

Korean J. Met. Mater. 2016;54(9):659-671. Published online 2016 Sep 5 DOI: https://doi.org/10.3365/KJMM.2016.54.9.659
Abstract
As a first step to optimizing the homogenization heat treatment following high temperature upset forging, the solidification segregation and the homogenization behaviors of solute elements were quantitatively analyzed for 1Cr-1.25Mo-0.25V steel ingot by electron probe micro-analysis (EPMA). The random sampling approach, which was designed to generate continuous compositional profiles of..... More
