Several 316 manual metal arc weld metals produced with commercial and experimental consumables were aged between 600 and 850 °C. This resulted in the dissolution of the δ-ferrite with the appearance of new austenite, M23C6, intermetallics σ, χ an

Tensile properties of a thick, multipass, submerged-arc (SA) weld-deposited type 316 are investigated by tests at room temperature and at 400 ° C and by microstructural and compositional analyses. The as-deposited metal, which shows a lower yield st

Many of the factors which give rise to the low and variable creep rupture properties of type 316 weld metals are not yet fully understood. In the present study two weldments fabricated using the same welding parameters, but with compositional differe

Helium was uniformly implanted into type 316 stainless steel and Sandvik HT-9 (12Cr-1 MoVW) to levels of 0.18 to 256 and 0.3 to 1 a.p.p.m., respectively, using the “tritium trick” technique. Autogenous bead-on-plate, full penetration, welds were

It has been known for some time that austenitic weldments exhibit low and variable creep rupture properties, but many of the factors controlling these properties are not well understood. In this investigation, two welds (Type 316) with similar compos

A series of PMR-15 resin specimens were isothermally aged at 288, 316, and 343 °C over a range of time. For PMR-15 aged at 288 °C, the samples were also subjected to different aging environments including: ambient air, dry air, inert (argon), and p

Uniform or localised corrosion resistance of stainless steels is attributed to the presence of a tenacious passive film formed on the surface, the thickness and chemical composition of which depends on the applied potential. The protective properties

Photolytic iodine laser (PIL), a new industrial laser in the market, offers much higher brightness than existing Nd:YAG and CO2 lasers. PIL has also a unique wavelength (1315 nm) that has not yet been tested for welding applications. In this work, th
