This article discusses the classification schemes for cast irons and describes the characteristics of major categories, including gray iron, white iron, ductile iron, compacted graphite iron, mottled iron, malleable iron, and austempered ductile iron. It also discusses some of the basic principles of cast iron metallurgy. When discussing the metallurgy of cast iron, the main factors of influence on the structure include chemical composition, cooling rate, liquid treatment, and heat treatment.

The most common type, gray cast iron features a graphite microstructure consisting of many small fractures. When gray cast iron is produced, the fractures open up to reveal the gray-colored graphite underneath the surface. With that said, gray cast iron offers similar compressive strength as steel.

Metallurgy Matters: Carbon content, steel classifications, and alloy steels

Steel is an alloy of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to iron. Many other elements may be present or added. Because of its high tensile strength and low cost, steel is used in buildings , infrastructure , tools , ships , trains , cars , machines , electrical appliances , and weapons. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms allotropic forms : body-centred cubic and face-centred cubic.

Advanced Steel Microstructural Classification by Deep Learning Methods

Generally, carbon is the most important commercial steel alloy. Increasing carbon content increases hardness and strength and improves hardenability. But carbon also increases brittleness and reduces weldability because of its tendency to form martensite. This means carbon content can be both a blessing and a curse when it comes to commercial steel. And while there are steels that have up to 2 percent carbon content, they are the exception.

Cast iron is a ferrous alloy that is made by re-melting pig iron in a capola furnace until it liquefies. The molten iron is poured into molds or casts to produce casting iron products of the required dimensions.

The paper focuses on an experimental topic relating to the field of friction welding process of a nodular cast iron. The microstructures, phase transformation, temperature distributions, microhardness, and tensile test are all studied within the framework of the paper in question. Both temperature and increasing temperature gradient at the axial center were higher than those at the periphery.

Чуть впереди, у остановки, притормозил городской автобус. Беккер поднял. Дверцы автобуса открылись, но из него никто не вышел. Дизельный двигатель взревел, набирая обороты, и в тот момент, когда автобус уже готов был тронуться, из соседнего бара выскочили трое молодых людей.

In book: ASM Handbook, Volume 1: Properties and Selection: Irons, Steels, and Classification of cast iron by commercial designation, microstructure, and fracture qualities to cast irons which approach those of steel in some applications.

Мрачный голос Стратмора вывел ее из задумчивости. - Единственный луч надежды во всей этой печальной истории - то, что Танкадо путешествовал. Есть шанс, что его партнер пока ничего не знает. Испанские власти обещали придержать информацию - столько, сколько смогут.

АНБ, - подумал.  - НБ - это, конечно, не болтай. Вот такое агентство. На другой стороне авениды Изабеллы он сразу же увидел клинику с изображенным на крыше обычным красным крестом на белом поле. С того момента как полицейский доставил сюда канадца, прошло уже несколько часов.
