Streszczenie:

Properties of cast aluminum components can be improved by strategically placing ferrous inserts to locally improve properties such as wear resistance and stiffness. A cost-effective production method is to cast-in the insert using the solidification of the molten aluminum as a joining method. Metallurgically bonding between the metals could potentially improve both load and heat transfer across the interface. The metallurgical bond between the steel and the aluminum has to be strong enough to withstand stresses related to solidification, residual stresses, thermal expansion stresses, and all o

In this study, the ageing effects on powder used for cemented carbide insert production are examined. Ageing is throughout this study, defined as the time dependent change of the magnetic properties: coercive field strength and saturation magnetization. Testing is done using eight different powder compositions stored in both air and in an argon cabinet for 10 weeks, where sampling is done at specific intervals. Samples are stored in vacuum sealed bags for a combined sintering at the last phase of the test. Magnetic properties are assumed to be dependent on the amount of oxides needed to be red

High Pressure Die Casting (HPDC) is low-cost technique for the mass production of complex, non-ferrous parts. Despite its benefits such as dimensional accuracy, surface quality and high production rate<br>some mechanical drawbacks limit use of HPDC in production of critical parts especially under dynamical loads. This study aims to improve impact resistance and surface hardness of die cast parts by means of tool steel inserts. These inserts act as a barrier between the impactor and die casting alloy, in order to avoid surface deformation and reduce stress localization which leads crack format

The effects of some heavy metals at different stages of food chains are examined. The uptake of Zn or Cd by Australian white wheat, <i>Triticum aestivum</i>, was investigated and this wheat fed to the herbivore, <i>Schistocerca gregaris</i>. The organs of these insects were then examined for accumulation. Accumulation occurred in all organs examined but was higher in the epidermis and mid-gut. <i>Nasonia vitripennis</i> (Hymenoptera) was used as a carnivore. The effects of Zn, Cd, Cu and Hg on the longevity and survival of this insect were examined together with total accumulation at three dif

Nickel is considered as a dificult-to-cut material, due to rapidly work hardening when machined. Because it shows high strength at high temperatures it is widely used as high temperature alloys in aerospacial components and more specifically is applied in the continuous casting industry, in molds which consist of a copper sheet with pure nickel electroplated, mounted over steel boxes, at the beginning of continuous cast process. The molten steel is poured into the tundish, then is driven to molds box, which must support the wear caused by steel sliding at high temperature. The principal aim of

Flapping wing micro air vehicles (MAV) have broad applications such as exploration in hazardous environment, reconnaissance, search and rescue. Ionic polymer metal composites (IPMC) have emerged as a promising material in actuators and sensors for use in flapping wing of MAVs. Though IPMC satifis es most of the criteria needed for bio-inspired design, achieving high stiffness, actuation force, frequency and flapping angle remains a challenge. The main objective of this thesis is to study the various factors which influence the actuation performance of IPMC by mathematical modelling, op

Utilizing high-k dielectric materials to replace SiO2-based gate as an insulator to eliminate high leakage current is necessary due to its larger physical thickness under the same electrical thickness. However, the degradation in carrier mobility and threshold voltage instability are the important issues in using high dielectric materials. In this study, as compared with pure ZrO2 nMOSFETs, the effect of add

Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. However, few studies on advantages of additive manufactured tools in high pressure die casting are published.The aim of this study was to investigate and quantify the effect of conformal cooling on microstructure and mechanical properties of high pressure die cast aluminum alloy.
