Steel is currently widely used in the industrial world. Due to its versatile uses, development of steel science has also broadened, leading improved processing methods. Welding a process joining two pieces metal using heat. Steel, containing carbon, prone oxidation and rust. The aim this study determine influence welding current variations on tensile strength, corrosion rate, micrographic struc...

3 IMR KINKEN Research Highlights 2012 IMR KINKEN Research Highlights 2012 To reduce the fuel consumption by automobiles, medium carbon steels for forging parts, such as shafts and connecting rods, must be further strengthened. When carbide-forming elements such as Ti, Nb, and V, are alloyed with carbon steels, a fine dispersion of alloy carbides and large precipitation hardening can be achieved...

Abstract This paper aims to obtain a fine wear-resistance cladding that can be applied in guide shoe of shearer. The performance two claddings fabricated by additive manufacturing technology, no chromium-high carbon (NCrHiC) and high chrome-high (HiCrHiC) claddings, was analyzed through series characterization experiments (optical microscope, hardness, coefficient friction, wear rate, surface m...

In this study, we performed scanning transmission X-ray microscopy with a spatial resolution of approximately 50 nm to investigate the two-dimensional mapping chemical states carbon in Fe–C alloy. The lamellar texture (pearlite) consisting ferrite (α-Fe) and θ-Fe3C an interval 100 was identified by absorption from 1s→2p excitation image. It clearly observed that there exist more than two types ...
