Abstract:

Bulk fully nanocrystalline grain structures were successfully obtained in ultralow carbon stainless steel by means of equal channel angular pressing at room temperature. Transmission electron microscopy (TEM) and high-resolution TEM investigations indicated that two types of nanostructures were formed: nanocrystalline strain-induced martensite (body-centered cubic structure) with a mean grain size of 74 nm and nanocrystalline austenite (face-centered cubic structure) with a size of 31 nm characterized by dense deformation twins. The results about the formation of fully nanocrystalline grain st

Abstract:

In this work, the evolution of the microstructure, phase composition and crystal structure of 3D products before and after heat treatment, obtained from the original steel 12Cr18Ni10Ti by various metallurgical methods of melting, was studied. The obtained 3D steel samples were subjected to heat treatment, then structural changes were investigated by metallography, X-ray phase (XRD) and X-ray structure (XRD) analyzes. The analysis showed that heat treatment did not increase the grain size of austenite in additive steels, but could lead to an increase in the proportion of ferrite.

Abstract:

H13 stool steel processed by selective laser melting (SLM) suffered from severe brittleness and scatter distribution of mechanical properties. We optimized the mechanical response of as-SLMed H13 by tailoring the optimisation of process parameters and established the correlation between microstructure and mechanical properties in this work. Microstructures were examined using XRD, SEM, EBSD and TEM. The results showed that the microstructures were predominantly featured by cellular structures and columnar grains, which consisted of lath martensite and retained austenite with numerous nanoscale

Abstract:

Reduced activation ferritic (RAF) martensitic steels are promising candidates for the first wall of fusion reactors. However, current manufacturing capabilities call for these components to be made by welding wrought plates. This limits design freedom and necessitates the use of post-weld heat treatments (PWHT) in accordance with the boiler and pressure vessel code. Additive manufacturing (AM) can offer a unique solution to solve this challenge by leveraging the layer-wise deposition strategy to come up with temper bead deposition techniques to eliminate post-processing heat treatments (PPHT).

Abstract:

Fracture tests of 10 plates with elliptical hole fabricated from Q235 steel with the thickness of 4mm were conducted. The effecting of sharpness of elliptical hole (a/b) on fracture mode and fracture ductility of structure steel was studied. The experiment results show that the first crack initiates at the edge of the major axis of elliptical hole and expands towards the thickness of the plates. And then the crack expands quickly vertical to loading direction until the specimen ruptures. The fracture ductility is low for the specimen with the sharp elliptical hole.

Abstract:

Stainless steels with harmonic-structure design have a great balance of high strength and high ductility. Therefore, it is imperative to investigate their fatigue properties for engineering applications. In the present work, the harmonic-structured SUS316L stainless steels were fabricated by mechanical milling (MM) and subsequent hot isostatic pressing (HIP) process. A series of ratcheting-fatigue tests were performed on the harmonic-structured SUS316L steels under stress-control mode at room temperature.

Abstract:

Austenitic stainless steels are widely used in automotive and marine environments because of their high toughness, corrosion resistance, and wear resistance. The present comparative study focuses on the microstructure and wear resistance of double-layer austenitic stainless-steel coatings prepared on a ductile iron substrate using circular spot high-speed laser-directed energy deposition (DED) and broad-beam laser-DED. The results indicate that while the deposition process does not alter the physical phase of coating, it does influence the preferred orientation of surface grains. Both coatings

Fabrication of friction reducing and anti-wear surface with regular micro/nanostructures is a hotspot of surface engineering studies nowadays. We present a simple and easily-controlled method for fabricating stainless steel-based nanostructures surface. First, by strictly controlling the number of femtosecond laser pulses, two kinds of nanostructures are fabricated. Then, forming mechanisms of nanodots and ripple structure are analyzed. Lastly, we obtained uniform large-area nanodots and ripple structures by adjusting the repetition rate of laser focus accurately. Therefore, this technique wil
