Excerpt from Composition and Heat Treatment of Steel Following the ingredients of and materials used in steel, comes the heat-treatment, as the two have moved along parallel lines, in the many investigations, experiments, and improvements that have been made, and seem to be inseparable. Each change in composition seemsto have altered the heat-treatment, and each improvement in heat-treatment seem to have altered the percentage, that is best to use, of some one or more element. Many different methods and various kinds of materials have been experimented with and consequently a great deal of useful informa tion has been obtained and many improvements of a radical nature made. New methods, new materials, and new apparatus have thus been brought into use for the heat-treatment of steel. These have enabled the hardener to get more definite, positive, and uniform results, and in this way the metal has been improved to a great extent. All of the information that could be obtained on this phase of steel making and working has therefore been recorded as carefully as possible. This also suggests ideas that would indicate that there is still room for important improvements or discoveries. One of these is the attaching of a positive and negative wire of an electrical circuit to the piece of steel to be hardened and place' it in a quenching bath. The current can then be turned on, the piece heated, the current turned off, and the piece quenched without moving it or allowing the air to strike the metal and oxi dize it. Another instance is the possibilities suggested by carbonizing steel with gases or chemicals and thus doing away with the old laborious method of packing the steel pieces in bone and charcoal. Still another is the iso-minute annealing of high speed steel and the possibility of a similar method being applied to carbon steel. In gathering together the data necessary to add to my own, very little credit has been given to individuals, as to make this correct is not only a laborious but a hopelessly impossible task. To illustrate this I have seen professors claim as their own discoveries, new principles, new methods, etc., that were developed and perfected by students in their classes, and shop foremen and superintendents claim as theirs, inventions made by men in the shop. Two important discoveries that developed into new kinds of steel were made through the mistakes of workmen in steel mills. Two men on the same job added the correct percentage of a material and thus this element was twice as large as it was thought would give good results. In fact, it was believed that it would injure the metal to add more than a certain percentage, but when this maxi mum percentage was doubled the metal was given properties that were very beneficial for certain purposes. None of us can add but a mite to the knowledge that we have obtained from others and because we are enabled to write it so it will be recorded in books and papers does not give us the privilege of claiming to be the originators of certain ideas.

Excerpt from Heat Treatment of Steel: Hardening, Tempering, Case-Hardening In general, any change in the composition of a steel results in some change in its properties. For example, the addition of certain metallic elements to a carbon steel causes, in the alloy steel thus formed, a change in position of the proper hardening temperature point. Tungsten or manganese tend to lower this point, boron and vanadium to raise it; the amount of the change is practically proportional to the amount of the element added. Just as a small proportion of carbon added to iron produces steel which has decidedly different-properties than those found in pure iron, so increasing the proportion of carbon in the steel thus formed, within certain limits, causes a variation in the degree in which these properties manifest themselves. For example, consider the property of tensile strength. In a ten-point carbon steel (one in which there is present but per cent of, carbon) the tensile strength is very nearly 25 per cent greater than that of pure iron. Adding more carbon causes the tensile strength to rise, approximately, at the rate of per cent for each per cent of carbon added. Carbon steels are divided into three classes according to the propor tion of carbon which they contain. The first of these embraces the unsaturated' steels, in which the carbon content is lower than per cent; the second, the saturated steels, in which the proportion of carbon is exactly per cent; and, the third, the supersaturated steels, in which the carbon content is higher than per cent.

Excerpt from The Working of Steel: Annealing, Heat Treating and Hardening of Carbon and Alloy Steel Advantage has been taken of a reprinting to revise, extensively, the portions of the book relating to the modern science of metallography. Considerable of the matter relating to the influence of chemical composition upon the properties of alloy steels has been rewritten. Furthermore, opportunity has been taken to include some brief notes on methods of physical testing whereby the metallurgist judges of the excellence of his metal in advance of its actual performance in service.

Excerpt from Address Heat Treating of Steel When we speak of seeing a metal under the microscope, we refer especially to our prepared sample that we are going to examine. We cannot take a fracture and look at it under a high power microscope, because in a fracture we would have high places and low places, and if we looked at it with a glass above 30 magnifications, we would probably have the moun tains in focus, but the valleys would not be, so that in order for us to study the structure of steel under the microscope it' is necessary for us to take our sample and polish it very highly, so that all the parts are on the same plane. After polishing we etch, that is, we apply a drop of acid and wipe it off quickly. The acid in that way brings out the demarca tion line between the grains or crystals, or has different action upon different crystals.

Excerpt from Forge-Practice and Heat Treatment of Steel Modern demands on the finished products of steel have necessitated rapid strides in the art of heat treatment of the metal. As the subjects of forging, hardening, tempering and annealing are so closely correlated it has seemed wise to add to Forge Practice a certain amount of material devoted to the other branches of the art. The introduction of heat measuring and hardness testing instruments, together with various other modern appliances, and up to date systems of doing work have made necessary a broader knowledge of heat-treating methods than was formerly the case: for after all the most important factor is the man doing the work.

Excerpt from The Resistance to Wear of Carbon Steel When two specimens of the same steel which have also been glven the same heat treatment are tested in the Amsler machine, the upper specimen, which travels at the lower angular velocity, loses more weight than the lower specimen. The appearances of the produced are quite difierent; the lower specimen has a muchh film. The films prodnced on steels of like composition and trea are shown in Figure Since it is the lower specimen which the heavier film and the upper specimen which suffers loss in weight, it was decided to mount the standard the lower shaft.
