We have developed a method for forming carbon nanotubes (CNTs) directly on the surfaces of stainless steel materials that are important industrially. Using plasma-assisted chemical vapor deposition (PCVD), CNTs are formed at comparatively low temperatures, thus avoiding excessive annealing and degradation of the stainless steel. Because the catalytic metals needed for CNT formation are containe...

Steel ball indentation and scratch adhesion testing of hot filament chemical vapour deposited diamond films onto AISI type 316 austenitic stainless steel substrates using two different interlayer systems, namely chromium nitride and borided steel, have been investigated. In order to compare the adhesion of these films with that of a well-known and strongly adherent system, detailed adhesion tes...

In metastable austenitic stainless steels, strain-induced martensitic transformation during plastic deformation enhances work hardening of the material, increasing its strength and in some cases also ductility.1,2) The presence of α’-martensite, however, may increase the susceptibility of these materials to hydrogen embrittlement phenomena, for example delayed cracking.3–6) Delayed cracking can...

Basic properties of the suggested phenomenological model of tribocorrosion wear are considered. Using a friction pair austenitic stainless steel-ceramic in acid electrolytes as an example, a good agreement between predicted data and experimental evidence was obtained.

Ultrasonic testing of austenitic stainless steel welds is often difficult because the ultrasonic beam is subjected to many perturbations : deviation, partition, distortions and sometimes ghost echoes. These perturbations are due to the anisotropic and heterogeneous metallurgical structure of the welds. We are carrying out a research program in order to evaluate the influence of the main paramet...

A method based on the kinetics of crystal growth has been developed and applied to the computation of three-dimensional microstrucuture in austenite-matensite steels. The detailed crystallography of the transformation is used to model a realistic martensitic microstrucuture during the transformation without an external system of stresses. The interaction energy based on the plastic work model i...

The objectives of the NGV (Next Generation Vehicle) Project were to demonstrate that stainless steel can be used to reduce weight and costs, and to improve safety and sustainability in structural automotive systems. The deliverables include enabling technologies, virtual technology for design and development, processing and testing. The compilation of the results as well as aspects such as new ...

The austenitic stainless steel (SS) has been used as a material for  building  ultra  high  vacuum  (UHV)  chamber.  Recently significant  efforts  have  been  concerned  a  comparing  the standard  cleaned  for  ultra  high  vacuum,  passivity  stainless. In  this work Austenitic  nanocomposites were  synthesize by sol-  gel method. The morphologies  and  topographies  of  the samples  h...

M. Ogórek, Z. Skuza, T. Frączek, Czestochowa University of Technology, Czestochowa, Poland The study examined layers were formed on the outer surface of austenitic stainless steel 304 under glow discharge conditions in the low-temperature and short-term ion nitriding. The outer layers analyzed in the work produced in parallel in the classical process of cathode and a novel method of “active scr...

Nano/submicron austenitic stainless steels have attracted increasing attention over the past few years due to fine structural control for tailoring engineering properties. At the nano/submicron grain scales, grain boundary strengthening can be significant, while ductility remains attractive. To achieve a nano/ submicron grain size, metastable austenitic stainless steels are heavily cold-worked,...
