Effects of Grain Boundary Microconstituents on Heat-Affected Zone Cracks in a Mar-M004 Weldment
Metals, 2018 Repair-welding of a cast Mar-M004 superalloy by gas tungsten arc welding was performed. Liquation cracks of the heat-affected zone (HAZ) in a Mar-M004 weldment were closely related to the presence of low-melting constituents along the solidified ...

Advanced Science, EarlyView.A dynamic reconstruction strategy was utilized to construct PtCu/Cu3P heterostructures on the surface of self‐supporting Cu3P nanowires. The loose porosity in the restructured layer, together with a dynamic “dissolution‐redeposition” equilibrium during electrocatalysis, enables the electrode to maintain a low, stable overpotential for 240 h at ampere ...
