Mechanical Properties of Boronized AISI 316, AISI 1040, AISI 1045 and AISI 4140 Steels
In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, ...
متن کاملUsing the Ultrasonic Nondestructive Methods for Prediction of Mechanical Properties of AISI 4140 Alloy Steel
Achieving the mechanical properties of steels after various manufacturing and heat treatment processes is significant and essential. In production lines, after producing the specific and standard samples, mechanical properties have been measured by destructive processes which cause waste of cost and time. In addition, destructive techniques cannot detect the miniscule changes made in mechanical...
متن کاملMicro Laser Welding of AISI 430 Ferritic Stainless Steel: Mechanical Properties, Magnetic Characterization and Texture Evolution
In the present work, a high power Nd:YAG laser has been employed to weld AISI 430 ferritic stainless steel thin sheets. Optical microscopy was used to study the microstructural evolutions during laser welding. Tensile test and microhardness measurement were employed in order to investigate the mechanical behaviors of welds. Also, vibrational sample magnetometry was used for characterizing magne...
متن کاملOptimization of process parameters for pulsed laser milling of micro-channels on AISI H13 tool steel
This paper focuses on understanding the influence of laser milling process parameters on the final geometrical and surface quality of micro-channel features fabricated on AISI H13 steel. Optimal selection of process parameters is highly critical for successful material removal and high dimensional and surface quality for micro-sized die/mold applications. A set of designed experiments is carrie...
متن کاملTensile Fracture Behavior and Failure Mechanism of Additively-Manufactured AISI 4140 Low Alloy Steel by Laser Engineered Net Shaping
AISI 4140 powder was directly deposited on AISI 4140 wrought substrate using laser engineered net shaping (LENS) to investigate the compatibility of a LENS-deposited part with the substrate. Tensile testing at room temperature was performed to evaluate the interface bond performance and fracture behavior of the test specimens. All the samples failed within the as-deposited zone, indicating that...
