Grain Refinement of Deoxidized Copper [PDF]

open access: yesMetallurgical 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 ...

The effect of the austenite grain refinement on the tensile and impact properties of cast Hadfield steel [PDF]

open access: yesMaterials 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.

Designing grain refinement passes for multi-direction forging: A phase-field crystal study

open access: yesJournal 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

Grain refinement efficiency of a new oxide-containing master alloy for aluminium casting alloys [PDF]

open access: yes, 2014
In this study, grain refinement efficiency of a new oxide master alloy based on MgAl2O4 was demonstrated on an A357 alloy. The grain size of the reference alloy was reduced by 50-60% with the addition of the master alloy and introduction of ultrasonic ...
