Design of Multiphase Compositionally Complex Alloys for Enhanced Hardness at Elevated Temperatures and Machinability: Comparative Study with Inconel 718

open access: yesAdvanced Engineering Materials, EarlyView.
This study compares the mechanical properties of Inconel 718 with two newly developed compositionally complex alloys (CCAs). Inco‐like‐H alloy demonstrates significantly improved wear resistance, surface finish, and hardness, notably at high temperatures. This CCA requires no heat treatment and is well suited for additive manufacturing. Its performance

Optimizing Laser Ablation of Stainless Steels for Volume Removal and Surface Quality Using Burst of Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...

A Novel Simplified Approach to Physically Simulate Wire‐Arc Directed Energy Deposition Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Scarcity of specialized titanium alloy wires and high experimental wire production costs impedes wire‐arc directed energy deposition (waDED) adoption in industry. A novel, wireless approach is introduced to accelerate and economize titanium alloy development.

The influence of the weld toe grinding and wig remelting weld toe rehabilitation techniques, on variable stresses, in case of cross fillet welds, reinforced with additional welding rows

open access: yesMATEC Web of Conferences, 2017
Variable stresses where the load value varies between a maximum and a minimum value, or varies the position in time, cause after accumulating a large number of load cycles in those structures, the emergence of drug fatigue.
