Residual Stresses in Castings Produced by Press Die Casting Technology
D. Novoselović, I. Budić, I. Samardžić, Mechanical Engineering Faculty in Slavonski Brod, University of Osijek, Croatia The influence of technological parameters on residual stresses in pressure die castings is analysed in this paper. In order for the residual stresses to be as low as possible the optimization of technological parameters is necessary. The centrally composed plan of experiment 2...
متن کامل"cast Iron -a Predictable Material " New Capabilities in Casting Process Simulation to Assess Iron Casting Production and Properties
The classical casting material cast iron is experiencing a renaissance. High strength CGI or alloyed cast iron components are substituting previously used non-ferrous castings in automotive power train applications. The mechanical engineering industry has recognized the value in substituting forged or welded structures with stiff and light-weight cast iron castings. New products such as wind tu...
متن کاملBimetallic Cast Iron Rolls – Some Approaches to Assure the Exploitation Properties
Although the manufacture of rolls is in constant improvement, the requirements for superior quality rolls have not yet been completely satisfied, in many cases the absence of quality rolls preventing the realization of quality laminates or of productivity of which rolling mills are capable. In the selection of materials several factors have to be considered including the type of rolling mill, t...
متن کاملMelting, Casting, and Processing of Nickel and Iron Aluminides Vinod
The nickeland iron-aluminide alloys are an important class of materials because of their unique resistance to oxidizing, carburizing, and sulfidizing environments at high temperatures. They also provide an interesting combination of high-temperature strength and wear resistance. Many applications have been identified for these materials including: furnace fixtures, heating elements, pumps, hydr...
متن کاملAbnormal Rolls in Hybrid
We report experimental and theoretical results on the conductive regime of electroconvection in hybrid aligned nematics. The drifting oblique/normal rolls below/above the Lifshitz frequency are observed at the onset of electroconvection under a.c. voltage. The experimental data on the threshold voltage, wavelength, oblique angle and drift period of the rolls as function of a.c. frequency are in...
