Abstract
γ-TiAl alloys have attracted interest as lightweight materials for structural applications at temperatures below 800
o
C. With recent improvements in microstrutural control of the γ-TiAl alloys, resulting in excellent creep properties and high temperature strength, their use can be extended to temperatures higher than 800
o
C. To increase.....

Abstract
The vacuum carburizing behavior of AISI 4115 steel according to acetylene flow rates (1, 5, 10, 20, 30, 40, and 50 sccm) and temperatures (900, 950, and 1000
o
C) was quantitatively investigated through microstructure, carbon concentration and hardness analyses. As the acetylene flow rate increased, the penetration rate of carbon.....

Abstract
Oxi-nitrocarburizing treatment was performed to improve the anti-corrosion and anti-wear properties of low carbon steels. The oxi-nitrocarburizing was carried out in 2 steps: a gas nitrocarburizing step at 560 ℃ and an oxidation step at 550 ℃ for 30 min with steamed water. The mechanical and chemical properties of the.....

DOI:
https://doi.org/10.3365/KJMM.2017.55.1.16
Abstract
Laser surface carburizing can be achieved by a laser alloying mechanism, which includes melting the graphite coated substrate and dissolution of the graphite in the liquid state. The drawback of laser carburizing is that process-induced cracks frequently form on the carburized surface as a result of carbon enrichment and the.....
