2041.全球锻造行业报告（2014-2018年）
[金属制品业,有色金属冶炼和压延加工业] [2014-07-18]
Forging is a process in which metals are shaped into desired designs by applying compressive forces. This technique is very robust compared to a number of other metal shaping techniques because of the strength acquired by the metal during forging. Some metals are processed hot while others are processed cold. There are a number of forging methods such as closed die, press, and upset forging; open die forging; cold forging; and closed die forging for non-ferrous metals. The Automotive industry is the major end-user of forged products followed by Engineering Machinery and Railway industries.

2044.新型汞合金在太空零件制造中的应用
[金属制品业,铁路、船舶、航空航天和其他运输设备制造业,黑色金属冶炼和压延加工业] [2014-03-21]
Sound amalgams can be fabricated by substituting Ga-In liquid for mercury; Cu-coated steel fibers bond well with the amalgam components. Inclusion of steel fibers significantly improved mechanical properties. An application scenario utilizing amalgams for in-space parts fabrication and repair was suggested. Procedure and materials need to be optimized.

2048.基于ProCAST的大型复杂空心叶片精铸的数值模拟
[金属制品业] [2014-02-15]
重型燃气轮机的叶片尺寸厚大,形状复杂,叶身部位为空心的曲面薄壁结构,铸件极易出现缩孔、疏松缺陷.为改进其工艺方案,利用铸造模拟软件ProCAST对大型复杂空心叶片铸件铸造过程的温度场、流场及固相分数的分布情况进行了模拟,对大型复杂空心叶片的型壳预热温度进行了优化；通过采用980℃的高温型壳预热,实现了大型复杂薄壁叶片的顺利充型.模拟结果预测的缩孔、疏松形成的位置与实际浇注结果十分吻合,采取改进措施后,铸件一次浇注成功,消除了缩孔、疏松缺陷.
