In this study, the tribological properties of three AISI 1045 steel samples were investigated. Two treated with ultrasonic shot peening (USP) and strengthening grinding process (USGP), respectively, while other one was only a polishing process. Sample properties, such as surface morphology, roughness, microhardness, elastic modulus, frictional coefficient, phase structures analyzed. Results sho...

A comprehensive benchmarking study has been carried out to determine the influence of mesh formulation and chip separation methods on reliability accuracy finite element modelling large diameter drilling operations. The Coupled Eulerian–Lagrangian updated-Lagrangian (with deletion) formulations available in ABAQUS/Explicit, together with re-meshing) DEFORM 3D are compared by simulating through-...

In this research, the TiC–Ni35A composite coating was fabricated on AISI 1045 steel substrate by laser cladding process. The cross-sectional morphology, microstructure, microhardness, and wear resistance of coatings obtained under different energy densities (E) TiC powder ratios (PR) were analyzed. According to results, all had a reliable metallurgical bonding with substrate. X-ray diffraction ...

In this investigation, MoSx/Cr coatings were deposited by direct-current magnetron sputter onto Ck45 (AISI 1045) plain carbon steel substrates. The MoSx/Cr ratio in the coatings was controlled by sputtering the composite targets. The chemical characterization was performed using EDX (energy dispersive X-ray analysis); the structural characterization was accomplished by X-ray diffraction (XRD) s...

Mechanical machining processes are common manufacturing strategies to re-shape materials to desired specification. The mechanistic approach has revealed the mechanics of the machining processes with various parameters determined. The aim of this work is to investigate the impact of swept angle optimization and their influence on the specific cutting energy in milling AISI 1045 steel alloy. This...

non-destructive eddy current (ec) technique has long been used to detect discontinuities in materials. recently, its application has been extended to characterize materials microstructure. in order to identify different microstructures, four plain carbon steel bars with different chemical compositions (aisi 1015, 1035, 1045 and 1080) were used in annealed condition. the pearlite percentage, car...

This paper presents a numerical investigation of the effects chamfered and sharp cemented carbide tools using finite element method-based DEFORM-2D software cutting parameters on different machining characteristics during orthogonal AISI 1045 steel. The objective is to study interactions between chamfer width, angle, angle speed feed rate temperature, effective stress wear depth. These were inv...
