A spur gear is one of the most common forms of precision cylindrical gear. In theindustry, reducing the weight of gears while keeping their useful properties hasbecome an even more pressing challenge. As a result, the investigators havemade many attempts to reduce the weight of the gears. Despite these efforts, theproblem still requires more resear...
Friction welding method is one of the most efficient and effective techniques for joining similar and dissimilar materials. The AISI 304 austenitic stainless-steel is a most common type of austenitic stainless steel which is used in various practical applications like automotive, food manufacturing, chemical applications, etc. Therefore, Therefore,...
In the present work, similar joint of AISI 304 austenitic stainless steel with a designed joint interface by 6 mm diameter and 6 mm depth, were processed by rotary friction welding route. Different parameters including forging pressure (192.4, 240.5, 288.6 and 384.8 MPa), friction pressure (192.4 MPa), frictional speed (560 RPM) and frictional time...
In this study, a rotary friction welding technique was used to join austenitic stainless-steel grade AISI 304. The effect of different forging pressure (192.4, 240.5, 288.6 and 384.8 MPa) on wear resistance of AISI 304 were examined using a modified pin on disc tester. The microstructure of the AISI 304 was examined as well using an optical microsc...
In this study that spur gears are chosen, contact stress of spur gear is presented under the effect of rotational speed. Three-dimensional simulation of dynamic analysis of gears designed and modeled using ANSYS software. The dynamic analysis included in the determination of dynamic stresses analysis. Contact stress is theoretically calculated and...
methods for improving the mechanical and metallurgical properties of friction welding joints for metals
The aim of this project was to improve the mechanical and metallurgical properties of the friction welded joints using rotary friction welding. To achieve this aim two different methods were used including joint design by producing pin with hole for stainless steel and fabricating Al-SiC composites. These were carried out by studying the effects of input parameters on such properties of two methods. The input parameters include friction pressure, forging pressure, friction time and frictional speed. Moreover, the results were compared with the properties of the base material in order to find the effectiveness and improvements on mechanical and metallurgical properties. The objectives of this project to investigate new methods to improve the mechanical (hardness, tensile, wear and impact) and metallurgical properties of friction welded joints of AISI 304 and Al-SiC composite.
