Selection of Metallographic Erosion Agent for Invar Alloys
摘 要
采用不同的浸蚀剂浸蚀因瓦合金金相试样,研究了浸蚀剂对热轧态和时效态因瓦合金金相试样的浸蚀效果。结果表明:过氧化氢-氢氟酸溶液浸蚀后热轧态和时效态的因瓦合金晶界均较浅,同时析出物轮廓不清晰;低倍金相浸蚀液和三氯化铁酒精饱和溶液能清晰显示因瓦合金的晶界,但细小析出物易被腐蚀剥落;王水能保持因瓦合金组织中析出物的完整并清晰显现,但晶界腐蚀不清;电解浸蚀可清晰地显示因瓦合金的晶界及析出物,并保持析出物的完整。
Abstract
Different erosion agents were used to erode metallographic specimens of invar alloys. The erosion effect of different erosion agents on hot-rolled and aged invar alloy metallographic specimens was studied. The results show that the grain boundaries of hot-rolled and aged invar alloys were relatively shallow after eroded by hydrogen peroxide hydrofluoric acid solution, and the precipitate profile was not clear. The low magnification metallographic erosion agent and the ferric chloride alcohol saturated solution could clearly show the grain boundaries of the invar alloys, but the fine precipitates were easy to be eroded and spallated. Aqua regia solution could maintain the integrity and clear appearance of precipitates in the invar alloys, but the grain boundaries corrosion was not clear. Electrolytic corrosion could clearly show the grain boundaries and precipitates of the invar alloy and maintain the integrity of the precipitates.
