Grain refinement of magnesium

The mechanisms involved in the grain refinement of magnesium alloys were investigated. Based on the findings, several attempts were made to develop a new, reliable grain refinement method, or maximise on existing method, for various magnesium alloys. The magnitude of grain growth during the solution heat treatment was investigated first so that more ...

Grain Refining of Pure Aluminum

2012
Grain refiners are currently used in casting aluminum alloys to reduce the grain size and to produce equiaxed grains during solidification of the alloys. Using inoculants to refine grains makes alloys castable but produces several disadvantages, including particle agglomerates, local defects, and impurities.

A new approach to the analysis of grain refinement

2007
Grain refinement of aluminium and magnesium alloys has been a challenging topic for decades and this is partly due to the complex nature of the mechanisms occurring during solidification and the lack of a common experimental method allowing comparison of data from different research groups.

Grain refinement of steel castings

JOM, 1967
Titanium inoculation has been shown to be capable of refining the as cast structure of AISI 4335 steel. This refinement consists of changing axed grains and reducing the spacing of the secondary dendrite arms. the structure from columnar to equi-When this steel is heat treated to high strength levels (250,000 psi tensile strength) by conventional ...

Grain refinement in electrogalvanized coatings

Materials Characterization, 2003
Abstract The effects of grain-refining additives on the morphology and surface roughness of zinc deposits plated at 80 A/dm 2 is presented. Atomic force microscopy (AFM) images show zinc deposits plated without additives are rough and are not of commercial quality.

Master Alloys for Grain Refinement

2019
Master alloys are routinely added into aluminum melts before casting for grain refinement purposes. The widely used master alloys contain titanium and boron in the forms of Al3Ti and TiB2 particles in an aluminum matrix. Upon addition into aluminum melts, Al3Ti dissolves into the aluminum melts and promotes the heterogeneous nucleation of the α-Al ...
