Experimental Study of Mechanical Properties of AISI 1045, AISI 1053 and AISI 4140 Steels

International Journal of Engineering and Advanced Technology, 2020
AISI 1045, AISI 1053 and AISI 4140 are the mostly used material for axle shaft of a vehicle. The comparative study of these materials definitely will help in selection of appropriate material for required condition. AISI 4140 has shown greater Young’s modulus, yield strength and tensile strength, but moderate ductility is observed. The lesser ductility

Amorphous Hydrogenated Silicon Carbide Interlayers: Chemical, Optical, and Tribological Behavior for Improving Adhesion of Carbon‐Based Films to Ferrous Alloy

Surface and Interface Analysis, Volume 58, Issue 4, Page 246-261, April 2026.
ABSTRACT Diamond‐like carbon thin films have been gaining attention in the last years due to their unique properties, such as low friction coefficient and high wear resistance. However, the lack of adhesion between DLC coatings and ferrous alloys complicates their wider industrial application.
