RISResidual Stress Control in Nozzle to Cylinder Butt Welds of Large-Scale Pressure Vessels Using Primary Plus Secondary Local PWHT Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study systematically investigated spot heating local postweld heat treatment (PWHT) for pressure vessel nozzle to cylinder butt welds through experimental and numerical analyses. A dual-stage local heat ...
Effects of Nano-TiO2 on CO2 Uptake and Polymorphs of CaCO3 in Early CO2-Cured Low-Heat Portland Cement
Publisher: American Society of Civil Engineers
Abstract: AbstractLow-heat portland cement (LHPC) is characterized by its energy savings and low CO2 emissions during production and low heat release during hydration due to its high
C2S content. However, the CO2 uptake capacity of ...
