Comparative Analysis of the Effects of Microstructures Formed After Hardening Heat Treatment on the Mechanical Properties of AISI 4140 and AISI 4340 Grade Steels
This study presents an experimental investigation into the mechanical and microstructural properties of AISI 4140 and AISI 4340 grade steels, which are widely used in the automotive industry, following hardening heat treatment. These medium-carbon alloy steels are critical for components that require high strength and...
