The influence of position in overlap joints of Mg and Al alloys on microstructure and hardness of laser welds [PDF]
Structure and properties of laser beam welding zone of dissimilar materials, AZ31 magnesium alloy and A5754 Aluminum alloy, are investigated. The microstructure and quality of the Mg/Al weld were studied by metallography, microhardness and optical ...

High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition
ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...

Infrared Thermography for Weld Inspection: Feasibility and Application [PDF]
Traditional ultrasonic testing (UT) techniques have been widely used to detect surface and sub-surface defects of welds. UT inspection is a contact method which burdens the manufacturer by storing hot specimens for inspection when the material is cool ...

Modeling of Physical–Chemical and Thermomechanical Properties of Glasses From Recycled Waste
ABSTRACT This research focuses on understanding the high‐temperature phase evolution occurring during the vitrification of heterogeneous construction and demolition wastes (CDWs). The aim of this project is to transform this widely distributed and mostly unused waste stream into a homogeneous, engineered, glass‐based material with predictable ...

ABSTRACT The phase diagram of the GeO2–CaO system was investigated using differential thermal–thermogravimetric analysis and the equilibration–quenching technique, followed by electron probe microanalysis and X‐ray diffraction. The Ca2Ge7O16 compound was confirmed to be stable, and a eutectic reaction of L → GeO2(hex) + Ca2Ge7O16 was identified in the ...

ABSTRACT Reliability, safety, and the lifetime of wind energy systems are mainly driven by the quality of each single component. Especially, large structures made of cast material or welded structures, such as the nacelle, the machine carrier, or the tower, are subjected to cyclic loading.

Effect of Repeated Loads on the Low Temperature Fracture Behavior of Notched and Welded Plates [PDF]
The influence of repeated loadings on the susceptibility of weldments to fracture in a brittle manner is studied for an ABS-Class C steel. The test members have consisted primarily of 12, 24 and 36 in.

Fuzzy logic approach in metals fatigue [PDF]
The fatigue behavior of metal structures is extremely complex. Many types of uncertainty exist in metal fatigue studies, including member geometry; shape and size of fatigue cracks; type, shape, and size of defects and discontinuities in the structural ...

Influence of the Addition of Strontium on Eutectic Aluminium Alloys
This paper studies the effect of strontium on eutectic aluminium alloy (LM6) and its mechanical properties, with the aim of impacting high strength and ductility. Four alloy samples of LM6 with varying amounts (0%–0.1%) of strontium were cast. Universal tensile and Micro Vickers hardness testing machines were used to determine the alloy’s mechanical ...
