摘　　要：为了提高柴油机涡流室镶块在高温、高压等恶劣条件下工作的可靠性及其寿命,本文对其材质进行了研究和论述。 Cr17A1Si2MoRE钢就是为开发适于我国国情、可靠而又耐久的镶块新材料而研制的。文中对该材料的化学成分、金相组织、机械性能及试验验证进行了分析和闸述。This paper describes that a new kind of material for use in diesel engine swirl chamber insert is developed in order to increase reliability and service life of insert at high temperature, high pressure and adverse condition. Crl7Al Si2MoRE steel is a new material developed by us. This new kind of material has features of reliability and durability and is suitable to the condition of our country. This material's chemical composition, metallurgical structure, mechanical property and test verification have been analysed.
