In order to assess the integrity of welded pressure vessel containing a crack, behavior three-point bending specimens made HSLA steel joint are tested at -40°C, and their fracture behaviour analyzed, as conservative measure crack resistance. Specimens were low-alloyed NIONIKRAL 70, by SAW process. Surface notches machined electro-erosion method in parent metal (PM), heat affected zone (HAZ) wel...

thermomechanical control process steel produced by rolling has a significant anisotropy. the elongated grains and inclusions formed during hot rolling of ferrite and low carbon hsla steels directly influence the anisotropy of the steel’s mechanical properties as a result of microstructural anisotropy. the present research deals with this anisotropy, and particular attention has been paid to the...

The effect of an electroless Ni-Cu-P coating on the fatigue behavior of quenched and tempered CK45 steel has been investigated. The fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. The results indicate that plating of the base steel leads to a fatigue life reduction. The d...

silica refractory bricks are used especially in the metallurgical industries, due to desirable properties suchas high melting point, rigidity, and high temperatures strength. in this research, different amount of sicwere added to silica refractory containing different binders such as borax, boric acid, calcium nitride,sodium tri poly phosphate, sodium hexa meta phosphate (shmp) and lime. physic...

this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...

M. Suliga, R. Kruzel, Czestochowa University of Technology, Czestochowa, Poland In the paper the influence of bidirectional bending on breaking force of steel cord has been assessed. Tests were carried out under laboratory conditions on three types of cord. It was found that bidirectional bending of steel cord cause the deterioration of strength properties and weakening of steel cord as a resul...

Axial fully-reversed strain-controlled ([Formula: see text]) fatigue experiments were performed to obtain data demonstrating the effects of building orientation (i.e. vertical versus horizontal) and heat treatment on the fatigue behavior of 17-4 PH stainless steel (SS) fabricated via Selective Laser Melting (SLM) (Yadollahi et al., submitted for publication [1]). This data article provides deta...

The heat-resistant steel after aluminized was treated by laser shock processing (LSP) with high power Nd:YAG laser, and then was tensile tested at 400 . The effects of the high °C -temperature behavior after LSP were analyzed from residual stress and fracture organization. The results showed that the yield strength and tensile strength of heat-resistant steel after aluminized were improved obvi...
