초록
The effect of aging on the precipitation of the σ phase and corrosion resistance in W-substituted, super-duplex stainless steel was investigated. The volume fraction of the σ phase and the current density increased as the aging temperature increased up to 750oC, and, then, they decreased. As aging time increased, the volume fraction of the σ phase and the current density also increased. The σ phase considerably influenced to corrosion resistance. When Mo was substituted for W in super-duplex stainless steel, the volume fraction of the σ phase and the current density both decreased markedly.
Abstract
The effect of aging on the precipitation of the σ phase and corrosion resistance in W-substituted, super-duplex stainless steel was investigated. The volume fraction of the σ phase and the current density increased as the aging temperature increased up to 750oC, and, then, they decreased. As aging time increased, the volume fraction of the σ phase and the current density also increased. The σ phase considerably influenced to corrosion resistance. When Mo was substituted for W in super-duplex stainless steel, the volume fraction of the σ phase and the current density both decreased markedly.
