Materials on Dies for Pressure Die Casting
In the contribution the stress of die materials of thermal fatigue is defi ned and material life is derived theoretically and compared with the measured values. The important properties of the die materials as thermal conductivity, coeffi cient of thermal expansivity, modulus of elasticity and mechanical properties are described. Binding to it single die materials as carbon steels and chrome-tu...
متن کاملThe densification mechanism of squeeze casting
The solidification process during squeeze casting is analyzed based on the classical solidification and plastic deformation theory. The linear relationship between punch velocity and the solidification rate is established if the density change of molten meals is neglected. To obtain defect-free castings, the punch velocity should be larger than the solidification rate. The densification mechani...
متن کاملWelding Recovery Methods of the Pressure Casting Dies
Welding hot-work tool steels, containing 0.3-0.6% of carbon, is difficult both because of the elevated carbon content and because of significant hardening resulted from large amounts of alloying elements. A development of welding technology, i.e. better quality of electrodes, modern welding devices, improved welding technologies and better steel quality, make welding of such steel types possibl...
