As an important problem in forging factories, dies are destroyed because of high wear rate, plastic deformation and thermal and mechanical fatigue at high temperatures. This paper is an investigation into        the use of nickel super alloy with different welding parameters. Three weld overlaid alloys of inconel625, as wear resistance hardfacing materials on H13 tool steel, with different weld...

A copper–germanium alloy (Cu–Ge alloy) was examined as a phase change material, at temperatures exceeding 600°C, for latent heat storage in solar thermal applications. First, the thermo-physical properties of Cu–Ge were using differential scanning calorimetry, thermomechanical analysis, and laser flash analysis. Second, to evaluate response reliability alloy, cyclic charge/discharge under vario...

Abstract The effect of solid solution temperature on microstructure and mechanical properties plasma welded nickel-based high alloy Incone l625 was investigated by treatment (The range is 950 °C to 1150 the intergroup interval 50 °C). results show that after at °C, chain carbides are precipitated austenite grain boundary base material. With increasing, carbon chains dissolve gradually boundary....
