Thermal and structural modelling of arc welding processes: A literature review

Measurement + Control, 2019
This paper presents a state-of-the-art critical review of the thermal and structural modelling of the arc welding process. During the welding process, high temperature in the welding zone leads to generation of unwanted residual stresses and results in ...

Inhomogeneity of Room‐Temperature Elastocaloric Effects in NiTi Alloys Fabricated by Laser Powder Bed Fusion

Rare Metals, EarlyView.
ABSTRACT NiTi shape memory alloys are among the most promising solid‐state refrigeration materials. In recent years, additive manufacturing methods for producing difficult‐to‐machine NiTi alloys have gained increasing attention from researchers. This work successfully produces NiTi alloys with good superelasticity at room temperature via laser powder ...

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites

Rare Metals, EarlyView.
ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.

Effect of the Fe Content on the Oxide Film Composition and Corrosion Resistance of Inconel 625: An XPS and Cyclic Potentiodynamic Polarisation Study

Surface and Interface Analysis, EarlyView.
ABSTRACT The present work focuses on investigating the effect of increasing Inconel 625 Fe content on the oxide film composition and corrosion behaviour through XPS and cyclic potentiodynamic polarisation (CPP) studies. Different proportions of ASTM A182 F22 steel and Inconel 625 were arc‐melted to achieve a range of Fe contents (2–15 wt.%) in the ...

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

steel research international, EarlyView.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of
