Since the feed materials of EAF are predominantly steel scrap, it inevitably contains an amount of copper in the range of 0.25 wt%-0.45 wt% [9] which are from waste cars, wirings and other electrical parts.
Nickel is the key element to suppress hot shortness and is always present in the steel scrap.
Experiment methodology Materials Fe, Fe-Cu and Fe-Cu-Ni alloys produced by the Materials Production Center at the Ames National Laboratory were used.

Print models that are made today still use hard materials, and materials with a flexible texture are still rarely used. [9].
Costs in 3D printing are very high due to the use of expensive software, printers, and printing materials[33].
The limitation of this research is that it still uses rigid materials because there are very few elastic materials that can imitate human tissue.

List of reliability issues linked to the MOS dielectric and interface passivation, also considering alternative high-k gate dielectric materials.
Materials which have been investigated as dielectrics on SiC include Al2O3 [28], HfAlO [26], HfAlON [29]; related silicates and lanthanides also deserve investigation [30].
Threshold voltage stability is another key MOS reliability metric [43] which must be proven out for new MOS materials and processing.

Introduction Composite materials have become increasing application in industries such as aerospace, automotive, mechanical engineering, civil and chemical engineering.
The material is assumed to be initially free of damage such as technical cracks (size in the order of a mm) and delaminations but not free of tiny defects/flaws (size in the order of microns) prior to loading. 1.3 Failure Theory Modelling the behaviour of materials remains one of the most difficult challenges in engineering.
-Verification of engineering approaches, based on a qualified FEA-output level when analysing the test specimen, is necessary.
For 'higher textile pre-forms' (woven fabrics, 3D, heavily stitched laminates, etc.) engineering models have to be developed.

Introduction Zinc oxide (ZnO), a II-VI group compound semiconductor with an energy band gap of 3.3 eV at room temperature, is a very promising material for electronic device applications due to its wide band gap and large exciton binding energy of 60 meV [1].
In the application part, ZnO-based organic composite materials have recently been attracted for the fabrication of next-generation nonvolatile ultrahigh-density memory devices [21].
The photoluminescence study of ZnO is interesting because it can provide valuable information on the quality and purity of the materials.
The memory mechanism obtained in polymer-nanocomposites materials is not yet explained well, however the trapping and detrapping of charges in inorganic nanoparticle is considered as the basis for this memory effect of polymer and inorganic nanocomposites devices [21, 22].

It is found from the research data of mechanical properties that the design of multilayer structure and the selection of transition layer are the key to solve the problem of bonding strength between film and substrate.
