摘要: <正> 一、前言 腐蚀和蠕变的交互作用常使金属构件过早地遭受破坏。因此,近十几年来,由于石油化工、航空、能源动力工业的迅速发展,高温腐蚀和蠕变之间的交互作用已普遍受到重视。含SO_2的混合气体、熔盐沉积物以及二者同时存在的高温腐蚀环境,是火力发电厂锅炉以及其他燃煤燃油装置等通常所处的腐蚀环境。近些年来,为了提高钢的持久强度等力学性能,开发了往钢液中喷射微细活性金属氧化物的方法。本工作研究喷射添加ZrO_2弥散微粒的FeCrAl合金在多种腐蚀环境下的高温蠕变行为,探讨该合金高温腐蚀与蠕变的交互作用。
Abstract:Creep behaviour of FeCrAl and FeCrAl-ZrO_2 alloys have been investigated at 600℃ under the stress of 115.2 MPa in corrosive environment. The corrosive environments under study include air, gas mixture of N_2-10%O_2-1%SO_2 and surface salt coating (75%Na_2SO_4+25% NaCl) of 2mg·cm~(-2) in the gas mixture. With the dispersion of ZrO_2 partitles, creep rates of the alloy remarkably decrease and creep lifes remarkably increase and sensibility of creep fracture in the corrosive environments decrease. The corrosion process facilitates crack initiation and crack extension during the creep at 600℃ for FeCrAl and FeCrAl-ZrO_2 alloy.
