00Cr12Ni10MoTi马氏体时效不锈钢的晶粒长大

对00Cr12Ni10MoTi马氏体时效不锈钢材料的晶粒长大规律进行研究,发现奥氏体化温度对00Cr12Ni10MoTi马氏体时效不锈钢的晶粒影响较大,温度低于900℃时,晶粒遗传原始锻态的晶粒形貌;900℃时,奥氏体重新形核、长大,奥氏体晶粒明显细化;温度高于1050℃时发生明显粗化。工程化热处理时的低加热速率和低冷却速率对00Cr12Ni10MoTi马氏体时效不锈钢的性能几乎没有影响,而模拟工程化热处理得到综合性能良好的00Cr12Ni10MoTi马氏体时效不锈钢。

Research on the Feasibility of Engineering Application for Solidified Sludge Landfill

The sludge was landfilled after solidification/stabilization treatment. This technology can solve the problem of much sludge treatment. But the study on engineering application is less common. There is a lack of corresponding research results about equipment, process and treatment effect. According to the above problems, this paper discusses the treatment process combining with sludge solidification/stabilization landfill field in Fuyong Town in Shenzhen City. Furthermore, the strength, moisture content, environmental indexes of treated sludge in field test was carried out in order to monitor the treatment effect. The results showed that the sludge solidification/stabilization equipment can meet the need of large-scale engineering application and the treatment process is relatively simple and the solidified sludge can meet the need of landfill.
