Metallurgical classification

Metallurgical classification. The crystallographic structure of titanium exhibits a phase transformation from a low-temperature close-packed hexagonal arrangement (i.e., a-hcp, alpha-titanium) to a high-temperature form body-centered cubic crystal lattice (i.e., 6-bcc, beta-titanium) at 882°C. This transformation can be considerably modified by the addition of alloying elements (Table 4.52) to produce at room temperature alloys that have all alpha, all beta, or alpha-beta structures.

Classification of differences in the state of pollution of the immediate surroundings of the ferrous metallurgical works was the subject of further investigations. A model of three loaded areas has, therefore, been made. The basis of the model was the knowledge of the emission structure, in particular the distance from the works and the specific territorial situation in the region investigated.

Separation of Solids from Solids in Liquids. The resistance offered to the fall of particles through a liquid is used in several methods of separation of particles. Some of these methods depend principally on differences in particle size and others on differences in specific gravity. All these schemes were developed in the metallurgical industry, where they are used to a much greater extent than in the chemical industry. The following arbitrary classification is offered for this equipment ... 

A process plant is a classification of factory which transforms materials in bulk. The feedstock and products may be transported by pipeline or conveyor, or in discrete quantities such as truckloads or bags, but they are recognized by their bulk properties. Examples of process plants are oil refineries, sugar mills, metallurgical extraction plants, coal washing plants, and fertilizer factories. The products are commodities rather than articles. 

This system of atmospheric classification is now being revised to create a new approach based on dose-response functions for steel, copper, and zinc. Because the corrosion of aluminum occurs by a pitting or localized mechanism, the traditional approach of using mass loss to determine severity of attack is often misleading. Atmospheric corrosion problems with aluminum alloys are most frequently a result of metallurgical conditions rather than environmental conditions, and the behavior of aluminum may be excluded in the upcoming revision of the ISO 9223-6 documents. 

There are three general classification systems used to identify stainless steels. The first relates to metallurgical structure and places a particular stainless steel into a family of stainless steels. The other two, namely, the AlSl... 

The Institute of Scientific Information of the USSR Academy of Sciences publishes sixteen abstract journals, known collectively as the Referativnyi Zhurnal. One of these sections is the Referativnyi Zhurnal, Khimiya which began as a semi-monthly publication in 1953. In 1955 Biologicheskaya Khimiya which is a part of it, began to be published separately. A metallurgical section commenced in 1956. The format of RZhKh, as it is known, with its arrangement of two columns numbered consecutively, resembles that of Chemical Abstracts, while the classification of the contents is more like that of Chemisches Zentralblatt. Each issue has its author index, and about 3,500 informative abstracts. The abstracts themselves are in Russian, but for non-Russian...
