Quench hardening is a common manufacturing process to produce steel components with reliable service properties. Although quench hardening is a vital part of production based on steel, it is also one of the major causes of rejected components and production losses. Distortion, cracking, achievement of desired distribution of microstructure, and residual stresses are the most important problems during quenching of steels. In order to solve this problem, the dependence of the properties of the final product on the physics of the process must be clearly understood so that analysis or experimentation can be used to design processes to achieve optimum quality at desired production rates. Modeling is one of the most crucial elements in the design and optimization of quenching systems.


Simulation of quenching: A review
Gür, Cemil Hakan (2012-09-01)
Quenching is an important part of the production chain of steel components. The final properties of the product are largely determined during this stage, and this renders quenching as one of the most critical stages of production, requiring design and optimization specific to the product. The simulation of quenching requires the solution of a multi-scale/multi-physics problem with complex boundary conditions because of the simultaneously occurring heat transfer, phase transformation, and mechanical interact...
Simulator of an additive and subtractive type of hybrid manufacturing system
Dilberoğlu, Mecid Uğur; Yaman, Ulaş; Dölen, Melik (2019-06-24)
Additive Manufacturing (AM) facilitates the production of intricate objects despite its weakness in attainable part quality and fabrication speed compared to the conventional manufacturing methods. To alleviate the problems arising as a natural outcome of AM methods, hybrid technologies become viable options by employing concurrent manufacturing procedures, e.g. synergetic additive and subtractive manufacturing (SM) actions. Hybrid workstations have recently opened up new dimensions to 3D-printing industry,...
Sensitivity Analysis of Distortion of Carburized Steel Shafts Using Computer Simulations
Yazır, Büşra; Evcil, Elif; Yıldız, Seçil; Davut, Kemal; Şimşir, Caner (null; 2016-12-01)
Carburizing and subsequent quenching heat treatments are commonly used industrial processes to improve the properties and performance of steel shafts. Undesired dimensional and shape changes (distortion) related to these treatments are still the most frequent reason for expensive and time consuming corrective operations, low performance during service and even product rejection. The major aim of this study is to identify the suitable control parameters for subsequent optimization of the carburized quenching...
Analysis and design for aluminum forging process
Öztürk, Hüseyin; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2008)
Aluminum forging products has been increasingly used in automotive and aerospace industry due to their lightness and strength. In this study, aluminum forging processes of a particular industrial part for the two different alloys (Al 7075 and Al 6061) have been analyzed. The forging part, forging process and the required dies have been designed according to the aluminum forging design parameters. The proposed process has been simulated by using the Finite Volume Method. In the simulations, analysis of the p...
Analysis of heat treatment effect on springback in v-bending
Sarıkaya, Onur Turgay; Darendeliler, Haluk; Department of Mechanical Engineering (2008)
Aluminum based alloys have wide area of usage in automotive and defense industry and bending processes are frequently applied during production. One of the most important design criteria of bending processes is springback, which can be basically defined as elastic recovery of the part during unloading. To overcome this problem, heat treatment is generally applied to the workpiece material to refine tensile properties. In this study, the effect of heat treatment on springback characteristics of aluminum stud...
