“…On the other hand, the quenching process will potentially cause some defects in material such as crack, distortion, and etc. [11][12][13][14][15], therefore, the other process might be investigated to reduce the cost production and to prevent the defects in material, so the aims of this research are to know the effect of silicon elements on the microstructure and mechanical properties of A517 grade Q processed by normalizing heat-treatment process. The addition of Si on A517 grade Q is expected to gain the suitable mechanical properties of A517 grade Q that is processed by the normalizing process by considering the microstructure of the material, and the normalizing process is expected to replace the quenching and tempering processes on A517 grade Q for pressure vessels, thus, resulting in a more economical process.…”

This research aims to investigate the effect Si on microstructures and mechanical properties of normalized pressure vessel steel A517 Grade Q. The Si contents were varied from 0.5, 0.9, 1.2, and 1.6. The normalizing process was carried out at 920 °C in 10 minutes. The microstructures were characterized by optical light microscope and Scanning Electron Microscope (SEM), and The mechanical tests were conducted by hardness, tensile, wear, and impact testing machine. The microstructures and mechanical properties were investigated. The results of the microstructures test show that the phases of the material are bainite and ferrite. The increase of Si content will refine and distribute the bainite phase in the ferrite matrix. The mechanical tests show that the Si content will affect the mechanical properties such as hardness, tensile strength, ductility, wear resistance, and toughness. The Increase of Si content from 0.5 up to 1.2 will increase the hardness, tensile strength, and wear resistance, and will decrease the elongation and toughness of the normalized pressure vessel steel A517 grade Q. The mechanical properties seem constant from 1.2 up to 1.6 of Si.

Surface hardening heat treatment, including carburizing and quenching, is widely used to prevent wear and rolling contact fatigue of vehicle power transmission system parts such as gears. However, distortion that occurs during heat treatment processes can present problems for improving the precision of gear shapes. Predicting distortion behavior accurately by a heat treatment simulation method could help to achieve better heat treatment quality and accuracy of parts. A heat treatment simulation of a gear tooth was carried out in this work by using the heat transfer coefficient during a gear heat treatment process. The tooth surface was divided into nine parts with different heat transfer coefficients. It was found that the difference between the actual deformation and the calculated deformation was smaller compared with the application of a uniform heat transfer coefficient at the tooth surface. By considering the distribution of heat transfer coefficient on the tooth surface for width and height direction, the heat treatment deformation prediction result became more accurate.
