In this contribution we analyze and discuss the microanatomy and histology of postcranial osteoderms of a number of "rauisuchians" from different localities of South America (Argentina and Brazil). The studied sample inc...

Laser powder bed fusion (L-PBF) technology has undergone rapid development in recent years. Owing to its advantages of high speed, efficiency, intelligence, and full flexibility, it exhibits significant potential for rea...

The effect of frozen storage (6 months) on the microstructure (microscopy, flatbed scanning and image analysis), quality (texture, moisture and specific volume) and starch retrogradation of the cake crumb were evaluated...

Butt welding between SLM-formed AlSi10Mg and rolled 6061 alloy (T6 state) was conducted by the tungsten inert-gas arc welding(TIG) method. The microstructure and mechanical properties of TIG welded joints under different...

Through the laser-wire coaxial additive manufacturing technology, laser melting deposition experiments of GH4169 superalloy under different offsets were carried out, and the effects of different offsets on the microstruc...

The Mossbauer studies of yttrium iron garnet (YIG) films grown on the gadolinium gallium garnet (GGG) substrate was realized for different films thickness (2.85 and 5.42 mm) at the applied external magnetic field. It is ...

In the past few decades, the discovery of topological matter states has ushered in a new era in topological physics, providing a robust framework for strategically controlling the transport of particles or waves. Topolog...

The theory of the preceding papers is generalized and the notation simplified. A cluster of molecules in a stable phase surrounded by an unstable phase is itself unstable until a critical size is reached, though for stat...

Abstract Friction Stir Welding (FSW) is the most promising solid-state metals joining method introduced in this era. Compared to the conventional fusion welding methods, this FSW can produce joints with higher mechanical...

Chemical modification of chitosan, specially grafting with different polymers is an important strategy in the production of bio-based materials with enhanced properties. In the present study, chitosan was grafted with n-...

Estimating integrated variance, using high frequency data, requires modelling experience and data crunching skills. Although intraday returns have attracted much attention in recent years, handling these data is ...

To meet the requirements of precision and high-performance diffusion bonding for titanium alloy structures, pure graphite was used as the position limitation block. Diffusion bonding tests of TA15 titanium alloy samples ...

Abstract For dissimilar metal welds (DMWs) involving nickel-based weld metal (WM) and ferritic heat resistant steel base metal (BM) in power plants, there must be an interface between WM and BM, and this interface suffer...

Abstract Currently, conventional single-sided friction stir welding is primarily suitable for joining thin plate aluminum alloys, and its application to thick plates is still challenging in terms of welding efficiency an...

Abstract The aluminum (Al)/steel transition joints used in ships are processed from composite plates, and their mechanical properties have a significant impact on the safety of ships. In this paper, the Al/steel composit...

The oleogelation process has become in a great interest area for the food sector. The aim of this study was to understand the effect of cooling temperature profiles (CTP) applied during oleogelation on microstructure and...

Abstract In the present work, austenitic stainless steel (ASS) 304 foils with a thickness of 50 µm were first annealed at temperatures ranging from 700 to 1100 ℃ for 1 h to obtain different microstructural characteri...

Abstract This study analysed the failure of dissimilar metal welds (DMWs) between ferritic heat resistant steels and austenitic stainless steels and investigated its influencing factors by means of numerical simulation, ...

Ophionephthys limicola Lütken, 1869 (Amphiuridae) is recorded for the first time from the mainland Caribbean coast of Colombia. Although its presence was already known from the island of San Andrés, C...

Abstract Al–Li alloy is a new structural material with the advantages of lightweight and high strength. The extrusion profiles of Al–Li alloy are widely used in aerospace and other fields, which can significantly red...

Abstract Creep is one of the most typical failure modes for the turbine blades of an aero-engine. The microstructure of the turbine blades after long-term service can be adjusted by rejuvenation heat treatment (RHT) to r...

The effect of high-temperature annealing on the Charpy fracture properties of 316L stainless steel manufactured via Selective Laser Melting (SLM) was studied at ambient (25 oC) and cryogenic (–196 oC, LNT) temperatures...

Abstract Laser oscillating welding was employed to fabricate Al-Si coated press-hardened steel (PHS) to improve the element homogeneity in the fusion zone. Laser oscillating welding was employed with various oscillation ...
