WebThe effects of deep cryogenic treatment on microstructure and properties of WC-Fe-Ni cemented carbides were investigated in this paper. The WC-Fe-Ni cemented carbides were deep cryogenically treated at about -196 degrees C for 2, 12 and 24 h. Web变形高温合金在发动机涡轮盘等领域应用广泛,目前涡轮盘受到低通量、小粒径砂粒的高速冲蚀产生的磨损现象引起人们的大量关注.本研究针对两种变形高温合金材料GH720Li和GH738,采用SiO2颗粒作为冲蚀粒子,通过改变冲击角度及冲蚀速度,研究实验材料的固体颗粒冲蚀磨损特性.冲击角度分别为:30°,60°,90 ...
WebThe hot deformation behavior of FGH720Li superalloy was investigated by hot compressive tests on Gleeble-1500D thermal simulation test machine in different temperatures and strain rates. The true stress-strain curves were obtained, and based on the deformation data, the constitutive equation of FGH720Li superalloy was built. http://wujin.jiancai.com/cnews/pengsheng102-2007403326.html
WebThe results showed that the fatigue properties of FGH720Li alloy was excellent, when tested at the temperature of 450°C and applied stress of 1230MPa, the fatigue life could exceed … Webjs水泥基防水涂料i型房屋漏水问题一直是被我们所忽视的问题,下了雨屋子开始漏水,大家会想办法解决漏水问题,但是当天气一放晴,这个问题又被人遗忘了。 通常楼房顶层出现漏水问题主要可分为外部和内部两种原因。有的是因为外部原因,也就是因为屋
