Available in PDF, EPUB and Kindle. Book excerpt: The hardening of steel in the zone of action of focused radiation from a laser in the free-generation mode and with modulated-Q is considered. The maximum extent of the hardened areas is estimated, taking into account the characteristics of the laser radiation. The heating and cooling rates of the material were determined theoretically. The surface hardening of metal products is of much interest in machine design. A great many methods of surface hardening of metals are known: high-frequency current hardening, volume hardening of PP (low-annealing) steels, volume hardening of cemented and nitro-cemented items, etc. With the exception of the electron beam all other methods of surface hardening do not permit obtaining case-hardening of micro-regions to a depth of some tens or hundreds of microns. However, use of an electron beam is not always warranted due to the high cost of the equipment and the requirement for placing the item being treated in a vacuum. Experiments have shown that after laser treatment of the surfaces of U8, 45, KhVG and other steels, the micro-hardness in the treatment zone is increased from 300-400 up to 900-1000 kg/sq mm, and in certain cases to 2200 kg/sq mm. In this connection it is of interest to discuss some aspects of the possible use of laser radiation for the thermal treatment of steels and alloys. The paper analyzes some experimental data on the surface hardening of a number of steels and theoretical estimates are made of the dimensions of the regions of hardening obtained after irradiation by a laser.

Download or read book History Developments and Trends in the Heat Treatment of Steel written by Peter Jurči and published by . This book was released on 2021 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steels and their heat treatment are still very important in modern industry because most industrial components are made from these materials. The proper choice of steel grades along with their suitable processing makes it possible to reduce the weight of the components, which is closely related to energy and fuel savings. This has decisive importance in branches such as the automotive, transport, consumer industries. A great number of novel heat- and surface-treatment techniques have been developed over the past three decades. These techniques involve, for example, vacuum treatment, sub-zero treatment, laser/electron beam surface hardening and alloying, low-pressure carburizing and nitriding, and physical vapour deposition. This Special Issue contains a collection of original research articles on not only advanced heat-treatment techniques--carburizing and sub-zero treatments--but also on the microstructure-property relationships in different ferrous alloys.
