Narrow gap submerged arc welding (NG-SAW) and narrow tungsten inert gas (NG-TIG) with multi-layer multi-pass techniques were used to join the advanced 9Cr CrMoV steels. The relationship between impact toughness microstructure of dissimilar welded joint fabricated by these two different was systematically investigated. By tests, results indicated that average energy specimen NG-TIG (154.0 J) five times as high one (29.2 NG-SAW. Interestingly, an amount fine second phase particles detected on...
In this paper, the amorphous Ce68Al10Cu20Co2 (atom %) alloy was in situ prepared by nanocalorimetry. The high cooling and heating rates accessible with technique facilitate suppression of crystallization on identification homogeneous nucleation. Different from generally accepted notion that metallic glasses form just avoiding crystallization, role nucleation growth behavior alloys is specified, allowing an access to ideal glass free nuclei. Local atomic configurations are fundamentally...
The formation and control of the residual δ-ferrite in Alloy 617/9% Cr dissimilar welded joint manufactured by single-layer or multi-layer multi-pass overlaying technique were comparatively investigated. was identified based on its lower microhardness carbon content than surrounding martensite matrix being free from precipitates. Patch-shape found heat-affected zone (HAZ) 9% steel adjacent to fusion line for weldment, while less smaller could be achieved employing technique. Attributing...
A facile electrochemical two-step strategy was adopted to fabricate Cu<sub>2</sub>O microsphere-nanosheets on flexible Cu foil with superior pseudocapacitive properties.
Attributing to sensitive fast scanning calorimetry, combined with focused ion beam and high resolution transmission electron microscopy, we observed the solidification structure of single Sn3.5Ag droplet quenched at controllable rate. Amorphous layers in nanometer adjacent some Ag3Sn crystals were directly detected. Based on solid state amorphization, a nano diffusion couple between primary formed β-Sn matrix intermetallic was put forward. Quenched 15 000 K/s, concentration gradient this...
Al-10Sn (wt.%) melt-spun ribbons with nano-sized Sn droplets (20–400 nm in diameter) embedded the Al matrix and bulk distributed at grain boundaries were prepared. Differential fast scanning calorimetry (DFSC) based on nanocalorimetry thin film technique was successfully applied to investigate rapid solidification behavior of cooling rates ranging from 103 104 K s−1. Two broad exothermic peaks observed DFSC curves. They ascribed various catalytic activity factors f(θ). The rate dependence...
