This paper analyzes the corrosion resistance and mechanical microstructural properties of a welded joint ductile cast iron using AISI316L stainless steel as filler material three different heat treatments: preheating at 250 450 ºC post-weld annealing treatment. The results show presence ledeburite interface between weld bead affected zone root pass, along with loss strength ductility when weldi...

Corresponding author, Email: [email protected] This work compares the weldability of ductile iron when: (I) a root weld is applied with a tungsten inert gas (TIG) process using an Inconel 625 source rod and filler welds are subsequently applie...

In this study, it was aimed to improve the surface hardness by applying gas nitriding treatment dual-phase ductile cast iron and produce irons with a good strength-ductility combination. Thus, has been tried develop high wear resistance, strength, ductility. Ductile specimens microstructure consisting of ferrite + martensite were produced oil quenching at 70 °C after intercritical austenitizing...

As cast iron with 10-15% of graphite, Ferro Casting Ductile (FCD) Iron material has better mechanical properties than the ones from Grey Cast Iron. Moreover, it is also close to Carbon Steel’s properties. Regarding this condition, FCD potential be used as a shear key, specifically, joint precast segmental concrete bridges. The objective paper study behavior applied key on wet using epoxy. To do...

The hardened alpha-case (alpha-case) layer inevitably forms on the surface of titanium castings when prepared by investment casting. Because the hardness of the alpha-case is incomparable to that of the interior structure, the perception exists that the alpha-case is difficult to remove during cutting, grinding and polishing. Grindability (ease of grinding) of cast cpTi and cast Ti-6Al-4V was e...
