Photomicrograph of alloy overheating showes fraction grain boundary coarsening and melt-back delta at first. 其过烧特征最初表现为晶界局部加宽和复熔三角形的出现。
The chromium depletion at a low-energy boundary segment introduced by twin emission into a random boundary was smaller than that of the original random boundary. 在大角度晶界上形成的局部的低能晶界的贫铬程度明显低于原来的大角度晶界的贫铬程度。
