随着铸造行业的转型发展,3D打印技术已经成熟的应用于制造铸造砂型,所制作的砂型不再单单作为铸造过程中的半成品,而是可以作为产品面向各铸造厂进行销售。但是目前对于砂型的检验标准存在缺失,对于砂型质量的把控和评定缺少依据。针对铸造砂型的尺寸精度,通过设计制作测量试块,给出了一种3D喷墨打印砂型的测量方法及评定标准,填补了目前铸造行业中这一领域在标准上的空白,对推动3D打印技术在铸造行业的应用以及砂型的
The properties of gray cast iron (GCI) are affected by density of matrix, size of flake graphite and primary austenite. In this paper, the Y-type specimen of GC
The effect of Si addition on the microstructure and mechanical properties of Al-Mg-Si-Zn aluminum alloys were investigated. Results show that the microstructure
Casting technology of thin-wall TiAl alloy turbochargers was studied by investment casting and numerical simulation. Misruns and gas holes were the main defects
Electroslag casting (ESC) is an important method to produce high quality castings. In this study, the ESC up-pulling inner mold method (EUPIM) was used to produ
Alloys with long-period stacking ordered structures (LPSO) have good properties and are highly regarded. Mg-Zn-Y alloy containing LPSO phase was prepared by the
Although the shell mould casting process has a wide range of application in many fields, the prediction of casting defects is still a problem. In the present wo
Nickel-based superalloy lattice sandwich structures present higher stiffness, higher strength and higher temperature resistance in comparison with other metals.
(Cu43Zr48Al9)98Y2 amorphous alloy bar was prepared by the arc melting copper mold absorption casting method, and then, the amorphous alloy was annealed at diffe
