Sinopsis
Excerpt from American Society for Testing Materials, Vol. 20
Technical difficulties have opposed themselves to the pro duction of pure compounds of molybdenum at low cost, but as soon as a constant supply of the raw material can be assured, these difficulties will be overcome. Molybdenum will then have a wide range of application inasmuch as it is now being used advantageously for improving steel to which it gives increased elongation.

Excerpt from American Society for Testing Materials, Vol. 20
Between 1902 and 1904, a number of molybdenum steels were made at the Creusot Works in France. The Iron and Steel Magazine for 1904 gives the heating and cooling curves of the following steels as made by E. Saladin, Metallurgical Engineer of these works.

Excerpt from American Society for Testing Materials, Vol. 20
By G.W. Sargent. Historical. From the following excerpt which is taken from Helmet and Body Armor in Modern Warfare, by Bashford Dean of the Metropolitan Museum of Art, New York City, it is evident that even as early as approximately 1330 A.D., molybdenum was used in the manufacture.of steel, though perhaps not knowingly. As this is written I learn from my friend. Dr. M.Mayajima of Tokyo, this interesting point, which he in turn had from the metallurgist, Dr. O.Kochi of the Faculty of Technology of the Imperial University of Tokyo. It appears that years ago a German steel expert analyzed a part of a sword blade made by the famous Japanese artist, Masamune (1330 =t=)and he discovered that the rare element molybdenum, doubtless as an impurity, in a certain proportion. This led the discoverer to determine the local source of Masamune salloy iron; thereupon he purchased this iron in large lots, much to the surprise of the Japanese who later, when they analyzed captured German cannon, decided where a part at least of the molybdenum ore was obtained. The early investigators of the effects of the addition of molybdenum to iron or steel, stated such steels were red short: Thus Thomas Blair in 1894, wrote of a case where LOper cent of molybdenum rendered good iron red short and utterly worthless; and John A. Mathews reports having found two steels containing 1.87 percent and 2.99 percent of molybdenum, respectively, both low in carbon, unforgeable, while a third steel with 0.95 percent of molybdenum did not develop this red short feature, although it was seamy. Mathews, however, added he did not beHeve the results obtained were due to the Tungsten and Chromium Alloys. Journal, Iron and Steel Inst., 1902.

Paperback. Condición: New. Print on Demand. This book approaches the origins of the shattered zones occasionally found in steel rails, adding to a discussion that has engaged metallurgists since the 1910s. Since members with shattered zones had not been in service, the author attributes their development to antecedent conditions of manufacture. The author's research suggests that the formation of shattered zones is confined to specific stages of fabrication. While the book focuses on examining shattered zones in steel rails, it also identifies and compares similar zones in a steel tire and rolled steel wheel. The results of the author's research have implications not just for rails but also for other steel products. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
