Abstract Non-penetration laser welding of lap joints in austenitic stainless steel sheets is commonly preferred in fields where the surface quality is of utmost importance. However, the application of non-penetration wel...

El diagrama de Transformación en Enfriamiento Continuo del acero ASTM A335 P91 presenta a bajas temperaturas dos dominios microestructurales básicos, ferrítico y martensítico, cuyos límites dependen de las condicion...

The paper presents the results of studies of the corrosion behavior of austenitic and ferritic steels in alkaline, sulfide, and chloride environments. Structural changes on the surface when the steels are kept in solutio...

In our study, annealing was done to AISI 310S stainless steel at 800 °C. The effects of these annealing on structural, morphological, mechanical and electrical conductivities were investigated. From XRD results, it has ...

Abstract With the growing interest in utilizing Mg and austenitic stainless steel (ASS) in the automotive sector, joining them together in three-sheet configuration is inevitable. However, achieving this task presents co...

Many feminists, including Virginia Woolf, consider Jane Austen as the 'Angel of the House'—a woman who conforms to the patriarchal values of her time. This paper aims to portray Jane Austen in a new light, as a distinc...

Lean duplex stainless steels (LDSS) emerged as a competitive duplex stainless steels (DSS) where Ni is partially replaced by lower cost alloying elements such as Mn and N. However, to date there has been little to no inf...

Abstract In order to control the ferrite and austenite percentage in duplex stainless steel welding, many researchers try to change the laser welding parameters and cooling medium, but ignore to study the influence of he...

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, ...

The microstructure evolution and performance characteristics of the heat-affected zone (HAZ) in laser welding of 10Ni5CrMoV steel are investigated. By designing novel thermal simulation specimens and utilizing a thermal ...

Casting processes show some weaknesses. A particular problem is presented when the workpiece needs to be subjected to heat treatments to achieve a desired microstructure. This problem arises from the microsegregation phe...

The article deals with tribochemical influence of the surface activity of biosynthetic oils on the operational efficiency and reliability of lubricated friction nodes under the critical conditions. It is proved that the ...

It has been shown that rolling an Fe–15Mn–5Si–9Cr–5Ni (wt.%) alloy at 800 °C followed by annealing at 650 °C gives a structure – a high density of stacking faults and enough austenite hardness – that promot...

Fe–Mn based alloys with more 12% at. of Mn are usually called High-Mn steels. Several technological properties of High-Mn steels are explained by the presence of the fcc-hcp martensitic transformation. This transition ...

Abstract The hot or cold processing would induce the change and the inhomogeneous of the material mechanical properties in the local processing region of the structure, and it is difficult to obtain the specific mechanic...

We want to make three comments to the article by Li et al. [1].The first one is the interpretation of the internal friction peak at 382 K, which they attributed to the Snoek effect, but other authors suggest that this ef...

The corrosion behavior of two wrought super duplex stainless steels (SDSS), UNS S32750 and UNS S32760, and a cast duplex stainless steel (DSS), DIN/EN 1.4517, was evaluated in 3.5 wt% NaCl and ASTM D1141 synthetic seaw...

Abstract The current research of the Q-P and Q-P-T process has been focused on controlling the heating temperature and holding time, or adding alloy elements into the steel to induce precipitation strengthening and impro...

Abstract Based on the advantages of triply periodic minimal surface (TPMS) porous structures, extensive research on NiTi shape memory alloy TPMS scaffolds has been conducted. However, the current reports about TPMS porou...

Abstract Microstructure and mechanical properties of GN9 Ferritic/Martensitic steel for sodium- cooled fast reactors have been investigated through orthogonal design and analysis. Scanning electron microscopy (SEM), tran...

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...

Bulk Ti–Ni–Cu–Pd alloys show decent thermal- and load-cycling stability, yet low strength and limited recoverable strain. Here, we design a gradient Ti–Ni–Cu–Pd ribbon via nanoscale dual-phase (nanocrystallin...
