Determination of the degree of grain refinement in irradiated U-Mo fuels [PDF]
Heliyon, 2018 A simple, repeatable method for determination of the degree of grain refinement in irradiated Uranium-Molybdenum fuels has been developed. This method involves mechanical potting and polishing of samples along with examination using a scanning electron ...

New grain refinement method for aluminum cast alloys without adding grain refiner.
Journal of Advanced Science, 2001 Grain refiner has conventionally been added during the casting process of grain refinement, but it has recently become a recycling problem, which calls for the efforts for development of a new grain refinement method. In this paper, a technological breakthrough has been achieved, where grain refinement was successfully completed by applying ultrasonic ...

Grain Refinement of Deoxidized Copper [PDF]
Metallurgical and Materials Transactions A, 2016 Abstract This study reports the current status of grain refinement of copper accompanied in particular by a critical appraisal of grain refinement of phosphorus-deoxidized, high residual P (DHP) copper microalloyed with 150 ppm Ag. Some deviations exist in terms of the growth restriction factor (Q) framework, on the basis of empirical ...

Designing grain refinement passes for multi-direction forging: A phase-field crystal study
Journal of Materials Research and Technology, 2023 Multi-directional forging is an effective plastic deformation method for polycrystalline grain refinement, and the degree of refinement is closely related to the number of forging passes. However, the relationship between the degree of refinement and the

The effect of the austenite grain refinement on the tensile and impact properties of cast Hadfield steel [PDF]
Materials Research, 2018 This paper studied the effect of the austenite grain refinement on the tensile and impact properties of a cast Hadfield steel (12 % Mn, 1.2 %C and 0.65 % Si). The austenite grain refinement was obtained by hafnium inoculation.
