WebQuestion: 7.4 Part of a pure Ni ingot with large columnar grains is welded perpendic- ular to the grains, as shown in Figure P7.4. Sketch the grain structure in the weld. Sketch the grain structure in the weld. WebApr 13, 2024 · It could be speculated that the carbon sources in the high-purity Mg ingot provide Al-C particles, which act as nucleants for Mg grains in the high-purity AZ91 alloy. Thus, it can be considered the main reason that high-purity AZ91 alloys have a finer grain structure than that of commercial-purity AZ91 alloys.

An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final … See more Ingots are generally made of metal, either pure or alloy, heated past its melting point and cast into a bar or block using a mold chill method.
