Finally, the latest progress in the grain refinement of cast Zn and its alloys is described, and future work on grain refinement is summarized.doi:10.1007/s11661-017-4275-7Zhilin LiuSpringer USMetallurgical and Materials Transactions AZ.L. Liu, Review of grain refinement of cast metals through...
Grain structure of cast sample Figure 1 shows the longitudinal macrostructures of solidified Al-7wt.%Si alloy under the application of a direct current of I DC = 152 A conducting through the two kinds of electrodes. In both of the two solidified samples, it was found that a large...
39,40,41,42, we employ high-intensity ultrasound to control the solidification and grain structure of AM-fabricated Ti-6Al-4V. This development enables complete transition of columnar prior-β grains into equiaxed fine grains (~100 µm), leading to a 12% improvement in both the yield str...

The structure of cast magnesium alloys (grain size and precipitate morphology and size) affects the properties of the products and the scope for use of the alloys. The structure can be controlled by minor additions of inoculants, which a... M Bamberger - 《Materials Science & Technology Mst ...
Metals are usually used inpolycrystallineform and, thus, dislocations are unable to move long distances without being held up at grain boundaries. Metal grains are not uniform in shape and size – their three-dimensional structure resembles that of a soap froth. There are two main methods of me...
Find a detailed explanation of metal grain structure analysis – including how to prepare samples for microscopic analysis and understand the structural properties of metals – with expertise and insight from Struers, the world’s leading materialographi
Box shaped die castings of the AM60 magnesium alloy have been made with a cold chamber high pressure die casting machine. The resulting microstructure is generally observed to consist of (a) a fine grained structure or (b) a mixture of fine grains and coarse grains which is either centred ...
