Excerpt from Tensile Properties of Rail Steels at Elevated Temperatures This paper reports the results of elevated-temperature tensile tests on specimens from these rails. The procedure of testing was the same as described 1n the previous paper. Table 1 gives the designa tion, the chemical composition, and source of the materials studied.

Excerpt from Tensile Properties of Rail and Some Other Steels at Elevated Temperatures A photograph of a series of test bars after test is shown in Figure 4. The brittle nature of the, fracture is evident. This temperature range, from 600° to 7 00° C., in which this. Rail steel showed such surprisingly low ductility, has been termed the secondary brittle range and the phenomenon secondary brittle ness. It will be referred to as such throughout this report.

Book Description
Excerpt from The Creep of Steel at High Temperatures Above red heat, steel has yielding characteristics not usually associated with it at ordinary temperatures. We do not, as yet, have sufficient information to indicate definitely into which class of solid or fluid flow hot steel belongs. It may be either a plastic solid or a viscous fluid, or combine the properties of both. A viscous fluid, of which pitch is a good example, has the flow characteristics Shown in curve (a) of Fig. 1. The rate of flow is proportional to the load, even down to the smallest values, and yet a great resistance may be Offered against loads acting for a short time. This class of materials has no true elasticity and therefore no yield point. A plastic solid, such as wet clay, has flow characteristics as shown in curve (b) of Fig. 1. Here we have a more complicated condition. Until the load reaches a certain value there is no flow or extension, but after this point is reached the flow increases regularly in proportion to the load in excess of this value. It will be noted that the flow curve does not reach zero at a definite value of load, but approaches the axis gradually. We do not know the exact cause of this departure from a straight line at low flow rates, but it is probably due to the fact that plastic solids are made up of grains or particles of various sizes and shapes and some are less resistant to pressure than others.

Book Description
Excerpt from Compression Tests of Structural Steel at Elevated Temperatures A series of tests on rolled structural shapes is included to give in formation on local Compressive buckling. Tests of round bars having slenderness ratios (l/r) in the general range 20 to 150 are included to cover the performance for a wide range of temperatures and loads. The results of these short-time tests have been compared with data available from fire tests of columns 1 2 for those results that were rela tively free from effects of load-assistance from the protective coverings. The total number of tests reported herein is 281. Of this number, 63 were tension tests and 50 compression tests at room temperature 159 were compression tests at elevated temperatures, and 9 were expansion tests.

Book Description
Excerpt from Effect of Service on the Endurance Properties of Rail Steels Fatigue failures are due to the repeated stressing of the structure at stresses greater than the endurance limit of the material in that structure. The endurance limit may be defined as that minimum stress which, if repeatedly imposed, will cause cracks. To develop which will progress under repetition of that stress, causing ultimate failure.

Book Description
Excerpt from Effect of Temperature, Deformation, and Rate of Loading on the Tensile Properties of Low-Carbon Steel Below the Thermal Critical Range It has long been known that increase in temperature above the ordinary atmospheric range (is accompanied by changes in steels, particularly in strength and ductility. A large number of interesting and important papers dealing with 'various phases of this subject have appeared from time to time, but as recently pointed out by Jeffries (3 4) 2 our knowledge is still unsatisfactory, and a better understanding of these changes will undoubtedly be of benefit to industry. White (35) is of the opinion that our knowledge of the tensile properties of steels at high temperatures is wholly inadequate and has not kept pace with advancement of knowledge in other branches of engineering, while Howe (38) long ago called attention to the apparent anomalies found in study ing the effects of work at temperatures under the thermal trans formations ou the properties of wrought iron and steel used in boiler construction. Certainly, from the standpoint of engineering design, it is important to know the variations in limit of propor tionality with changes in temperature, but unfortunately this is the more difficult to determine of those factors considered in tensile tests, and the data available are con icting.

Book Description
Excerpt from On the Effect of Time and Temperature on the Strength of Steel and Iron The behaviour of iron and steel under simple stresses of various kinds has long been a subject of investigation by the Engineer. And very complete data are available for use in designing structures in metal. When iron or steel is subjected to tensional stress sufficient to cause a permanent stretch in the material, it is well known that the ductility of the material is reduced, and that ultimately the elastic limit rises.
