Abstract
IN792, a Ni-based superalloy, exhibits excellent mechanical properties at medium and high temperatures (600~900oC). However, it is known to be very susceptible to casting defects such as hot cracking and hot tearing during casting. This study investigated the effect of alloy elements such as Hf, Zr, and B on the.....

Abstract
The solidification and phase transformation behaviors of IN625 with low C and Fe were investigated through directional solidification and quenching experiments. The primary and secondary dendrite arm spacing decreased exponentially as the solidification rate increased, demonstrating good agreement with theoretical equations. The MC carbide formed at a constant temperature gradient.....

Abstract
In this study, the relationship between solidification cracking and epitaxial growth behavior with the high-speed laser surface melting of a directionally solidified 247LC superalloys was fundamentally and metallurgically investigated, to develop a successful welding procedure for the next generation of gas turbine blades. Under typical laser surface melting conditions (scan.....

DOI:
https://doi.org/10.3365/KJMM.2023.61.2.126
Abstract
The efficiency of gas turbines depends on the gas turbine working temperature. Single crystal blades are being applied more often than equiaxed blades in gas turbine engines, to increase the turbine inlet temperature, resulting in enhanced turbine engine efficiency. Single crystal blades endure creep conditions at high temperature better than.....

Abstract
The CMSX-4 superalloy including refractory elements was directionally solidified using the seed of a [001] single crystal to control the growth direction to [001], where solidification velocity was changed from 25 to 160 μm/s. In the log-log plot between spacing and solidification velocity, the primary dendrite arm spacing and secondary.....

Abstract
Directional solidification experiments were carried out to estimate the effect of solidification velocity and temperature gradient on primary dendrite arm spacing (PDAS) in the Ni-based superalloy, CMSX-4 alloy. The specimens were solidified at velocities of 1, 5, 25, 50 and 100 mm/s under given temperature gradients of 12.5, 18, 23.....

DOI:
https://doi.org/10.3365/KJMM.2018.56.8.589
Abstract
Martensitic 10Cr1MoW steels are widely used for high temperature components in turbine engines because they have good mechanical properties and corrosion resistance. Delta-ferrite can form locally in large ingots and the ferrite phase degrades the metal’s high-temperature properties. To decrease the fraction of delta-ferrite the solidification process should be controlled......
