Residual stress state in planar tubular K-joints, in the chord within the gap region between the two braces, is studied using numerical weld modelling. The motivation comes from past full-scale fatigue tests on tubular trusses made of various steel grades ...
In this paper research work on welded butt weld connections between hot-rolled seamless tubes and steel castings are presented. Comparison is made between different weld preparations for the butt welds including different steel grades, repair methods, the ...
Five different grain sizes are produced in 0.17 wt% carbon steel using varying rates of cooling from austenitization temperatures. Controlled furnace cooling from 1100 °C and 950 °C produces coarse ferrite grains of 40 µm and 32 µm diameter, respectively, ...
An automatic method to colorize and quantify the classical Pitsch, Kurdjumov-Sachs, Greninger-Troiano and Nishiyama-Wasserman orientation relationships in the electron backscatter diffraction maps of martensitic/bainitic steels is detailed. Automatic analy ...
SentryGlas®(SG)-laminated reinforced glass beams are numerically investigated. This innovative structural typology consists of a composite section in which the typical brittle behaviour of glass is overcome by means of stainless steel sections able to prov ...
A 'one-step' theory based on Pitsch distortion is proposed to explain the continuity between the orientations of the Kurdjumov-Sachs (KS), Nishiyama-Wassermann (NW) and Pitsch variants observed on the electron backscatter diffraction pole figures of marten ...
Micro-compression experiments were carried out on micro-pillars, with nominal diameter of 10 mu m and height 20 mu m, and fabricated from a high-chromium tempered martensitic steels developed for nuclear applications. An analytical method was proposed to c ...
The crystallography of bainite, transformed isothermally at 450 °C in 0.2C-2.0Mn-1.5Si-0.6Cr steel, was investigated by electron backscatter diffraction (EBSD) analysis. The orientation relationship (OR) was found to be closer to Nishiyama-Wassermann (N-W) ...
The objective of this project is to analyse welding processes in high strength low-carbon steel grade S690 in numerical simulation with MORFEO codes and in experiments with a Gleeble® thermo-mechanical simulator instrument. The influence of phase transform ...
Using high-strength steels for pressure shafts and tunnel liners and taking into account significant rock mass participation allows the design of comparatively thin steel liners in hydropower projects. Nevertheless, during emptying of waterways, these stee ...
