To elucidate the mechanisms of deformation and a state plastic stability at front Lüders bands during tensile test, metastable austenitic transformation-induced plasticity (TRIP) steels with different dislocation densities ferritic were characterized via macroscopic-DIC-based stress–strain investigations scanning electron microscopy (SEM). A direct correlation between curves measured strain dis...

Abstract The Mechanical and Stretch-Bend Failure studies on Ultra High Frequency Pulsed Gas Tungsten Arc Welded dissimilar joints of AISI409-AISI430 Ferritic Stainless Steels were conducted. Welding was conducted with 5 ultra high frequencies (50 Hz, 150 250 350 450 Hz). characteristics evaluation the included tensile strength, microhardness variations across welds creep. Microstructural metall...

The application of a bipolar electrochemistry technique to simulate the galvanic corrosion behaviour dissimilar stainless steels is introduced. allows comparison response by controlling extent localised as function an applied offset potential. setup was explored performance type 420 ferritic and 304L austenitic steels, yielding information about anodic vs. cathodic these materials when in close...

Steels with regulated austenitic transformation during exploitation (RATE) are a new class of ferritic-based tungsten-free tool steels for hot forming. The study obtained quantitative data on the high-temperature strength RATE steel composition after quenching and tempering. stress-strain curves plotted tendency to strain hardening at temperatures 450 750 °C is estimated. It was established tha...

In order to determine the potential benefits and limitations of aluminide coatings, coatings made by chemical vapor deposition (CVD) on Feand Ni-base alloy substrates are being evaluated in various hightemperature environments. Testing of coatings on representative ferritic (Fe-9Cr-1Mo) and austenitic (type 304L stainless steel) alloys has found that high frequency thermal cycling (1h cycle tim...

This paper studies the buckling behaviour and design of welded I-section stainless steel columns. Experimental numerical structural performance data together with methods for columns available in literature have been collated reviewed. A modelling programme including validation parametric has carried out to supplement experimental assessment existing codified proposed flexural formulations Colu...
