Probing true creep-hardening interaction in weld simulated heat affected zone of P91 steels
Journal of Manufacturing Processes, 2019The inducement of this paper was to discuss the novel perspective in establishing true creep-hardening interaction at room temperature by hardness and at high temperature by impression creep testing in two boron modified P91 steels.

Crack Arrest Toughness of a Heat-Affected Zone Containing Local Brittle Zones
Journal of Offshore Mechanics and Arctic Engineering, 1996Abstract The awareness of the presence of local brittle zones (LBZs) in the heat-affected zone (HAZ) of welds has led to the requirements for minimum initiation (CTOD) toughness for the HAZ for critical applications (API RP 2Z, CSA S473).

Characteristics of GTA fusion zones and heat affected zones in superalloy 713C
Materials Science-Poland, 2012In this paper, metallographic examinations, characterising microstructural changes in the 713C superalloy subjected to remelting by GTA method, are presented. In the fusion zone, precipitation of M23C6 or M6C carbides based on chromium and molybdenum was observed.

Subcritical heat affected zone softening in hot-stamped boron steel during resistance spot welding
Materials & Design (1980-2015), 2018Highly non-uniform temperature gradients experienced by workpieces during resistance spot welding (RSW) can lead to the formation of a subcritical heat affected zone (SCHAZ), a region prone to “premature” failure for ultra-high strength steels.

Dispersoid-free zones in the heat-affected zone of aluminum alloy welds
Metallurgical and Materials Transactions A, 2000The local microstructure in the heat-affected zone 1 (HAZ1) of a laser beam-welded Al-Mg-Si-Cu aluminum alloy is investigated closely. Dispersoid-free zones (DFZs), where the dispersoids of the base material (BM) are dissolved, are found in the vicinity of the fusion line (FL).

Austenite Grain Growth Simulation in Welding Heat-Affected Zone
Materials Science Forum, 2018To predict austenite grain growth behavior in the heat-affected zone (HAZ) in low alloy steels, a new calculation model is proposed herein. This model mainly considers the solute-drag effect and pinning effect, which restrain the austenite grain growth. To calculate the solute-drag effect, the grain boundary concentration of each element is obtained by
