Korean J. Met. Mater. 2017;55(12):825-835.   Published online 2017 Dec 4
DOI: https://doi.org/10.3365/KJMM.2017.55.12.825

The effects of cooling after solution heat treatment on the microstructure and mechanical properties of light-weight steels were investigated using Fe-30Mn-xAl-0.9C alloys containing 9.0–12.8 wt% Al. Lab-scale specimens (thickness: 10 mm) of the alloys were cooled by different cooling rates from -337 to -0.053 ℃/s using water, air, and furnace..... More

Korean J. Met. Mater. 2017;55(5):363-371.   Published online 2017 May 9
DOI: https://doi.org/10.3365/KJMM.2017.55.5.363
The effects of the annealing temperature on the microstructure and tensile properties of cold-rolled light-weight steels are investigated using two Fe-30Mn-xAl-0.9C alloys that contain different Al content. The initial alloy microstructure is composed of a single austenite or a mixture of austenite and ferrite depending on the nominal aluminum content.... More

Korean J. Met. Mater. 2017;55(2):132-138.   Published online 2017 Feb 2
DOI: https://doi.org/10.3365/KJMM.2017.55.2.132

Investment casting for the thin (4 mm thick) rectangular tube (40 mm wide, 80 mm high and 200 mm long) was carried out numerically and experimentally for Alloy 738, which is a precipitation-hardened Ni-base superalloy. Two types of rectangular tubes, one with a regular array (10 mm by 10 mm..... More
