Specimens were induction hardened at 1000 Hz for 6, 10, 14, 18, 27 s, respectively, in the inductor which was a three-turn coil with a coupling distance of 2.8 mm. Normalised and induction Case microstructure in induction surface hardening of Jul 18, 2018 · The microstructure and resultant mechanical properties of the hardened case produced in steels by induction surface hardening are discussed. The development of the final structure is followed throughout its characteristic evolutionary stages; its dependence on heating and cooling rate, maximum temperature of the treatment, composition, and initial microstructure is described in detail
Jan 20, 2016 · A 0.27 mm-thick grain-oriented silicon steel sheet with extra-low carbon was successfully produced by a novel processing route including strip casting, normalizing, two-stage cold rolling with an intermediate annealing, primary annealing, and secondary recrystallization annealing. The evolutions of microstructure and texture along the whole processing route were investigated with a special Fatigue test results of surface hardened components to Jan 01, 2018 · Hence, one layer represents the induction-hardened surface and the second characterizes the base material. The aim of this elaborated method is a more reliable computational estimation of fatigue life among other assessments based on technological benefit factors for components designed for the high cycle fatigue (HCF) regime by taking into Fertilization regime interacts with fall temperature in Nov 01, 2014 · Four fertilization levels were differentiated in both locations:(1) conventional low (C) and (2) conventional high (C+) fertilization, where the fertilizer was applied weekly at a constant rate of 1.57 and 8.3 mg N per seedling respectively, for 21 weeks from May 20 (Julian day 140) to mid October (Julian day 289) (33 and 175 mg N in total
Nov 29, 2018 · In the automotive manufacturing industries, heat treatment processes such as induction hardening or case hardening are required to meet the daunting demands of the customers in terms of quality and load-bearing capability of individual components. One of the key automobile engine components which almost always goes through some surface hardening is the transmission output IOP Conference Series:Materials Science and Engineering Apr 14, 2016 · Induction hardening:Differences to a conventional heat treatment process and optimization of its parameters A Vieweg, G Ressel, P Prevedel, P Raninger, M Panzenböck, S Marsoner and R Ebner View abstract View article PDF Microstructure and texture evolution of ultra-thin grain Mar 15, 2017 · A 0.1 mm-thick grain-oriented silicon steel sheet was successfully produced using strip casting and three-stage cold rolling method.The microstructure, texture and inhibitor evolution during the processing was briefly analyzed. It was found that Goss texture was absent in the hot rolled sheet because of the lack of shear deformation.

Aug 01, 2018 · Comparison of environmental tobacco smoke (ETS) concentrations generated by an electrically heated cigarette smoking system and a conventional cigarette. PubMed. Tricker, AnthonyInduction Hardening vs Conventional Hardening of a Heat Induction quench and temper experiments were performed, both with heating times 1 s. A significant change of the residual stress state was observed, leading to a shift from compressive to
