Heat Treatment Of Steels As An Art To Improve Their Service Performance Has Been Practised Ever Since It Started To Be Used As Tools And Weapons.However, The Scientific Basis Of Heat Treatment Of Steels Became More Apparent Only In The First Half Of This Century And Still Some Gaps Remain In Its Complete Understanding.Earlier Books On Heat Treatment Of Steels Mainly Emphasised The Art And The Empirically Arrived Principles Of Heat Treatment. In The Last Few Decades, Our Understanding Of Phase Transformations And Mechanical Behaviour Of Steels, And Consequently Of Heat Treatment Of Steels, Has Considerably Increased.In This Book On Principles Of Heat Treatment Of Steels The Emphasis Is On The Scientific Principles Behind The Various Heat Treatment Processes Of Steels. Though It Is Expected That The Reader Has Sufficient Background In Phase Transformations And Mechanical Behaviour Of Materials, First Few Chapters Review These Topics With Specific Reference To Steels. Basic Principles Of Various Heat Treatment Processes Of Steels Including Surface Hardening Processes, Are Then Covered In Sufficient Detail To Give A Good Overall Understanding Of These Processes. The Detail Engineering Aspects Are, However, Omitted. These Are Easily Available In Various Handbooks On Heat Treatment. The Book Also Covers Heat Treatment Of Tool Steels And Cast Irons.The Book Has Been Well Written And Can Be Used A Textbook On Heat Treatment For Undergraduate Students. It Is Also A Good Reference Book For Teachers And Researchers In This Area And Engineers In The Industry.

The high-carbon steels require extreme care in the various heat-treating processes, and their use is discouraged by some on this account. The arguments advanced against its use appear to a skilled man without foundation, because men skilled in this branch of work can be had if they are given the necessary inducements. The higher the carbon the lower the critical point of the steel. If the operator bears this fact in mind he will have no trouble in determining the proper heats to employ in forging, annealing and hardening high-carbon steel. The idea entertained by some manufacturers that they must use a steel that fits the ability of their employees seems to be without proper foundation. It is better to use steel suited to requirements, and then employ workmen capable of properly treating it. The percentage of carbon is many times denoted by the term "temper." When used in this connection it has no association with the "letting down" process known as drawing the temper after hardening. The following table gives the uses of steel of various carbon contents as adopted by at least one manufacturing concern, and conforms very closely to general usage. It cannot be regarded as absolutely correct under all conditions, but answers as an approximate guide. orffi!
