Metallurgical and mechanical analysis from thixoforging steel shape

Effect of Stress Relieving on Mechanical and Metallurgical Properties of Shielded Metal Arc Welded Joints of A517 Steel

Stress relieving is a common practice among manufacturing codes for reducing the magnitude of residual stresses in welded, quenched, and tempered steel structures and pressure vessels. The present work investigates the effect of stress relieving at 480, 560, 620, and 680°C on the microstructure and mechanical properties of 20 mm ASTM A517 Gr. B steel plate weldments produced by shielded metal a...

Effect of Ultrasonic Vibration on the Metallurgical Properties of Steel

Comparison of Mechanical, Metallurgical Properties of 17-4PH Stainless Steel between Direct Metal Laser Sintering (DMLS) and Traditional Manufacturing Methods

The purpose of this research was to analyze and compare the mechanical properties of parts made using both Direct Metal Laser Sintering (DMLS) and traditional manufacturing methods like casting or forging. Previous research in DMLS was conducted using various materials, but there has been very little done for 17-4PH stainless steel. All the samples used for testing were conducted using the EOSI...
