Abstract:
The hot deformation behavior of NIMONIC 80A was studied in the temperature range of 900 ~ 1200°C by employing the hot compression tests with the strain rates varying between 0.02~20 s-1. The results showed that the strength during hot compression increased with increasing the strain rate and decreasing temperature. [..]

Abstract:
Zn and Mg- based alloys are promising materials for medical implants because the mechanical characteristics of their alloys are close to human bone and zinc and magnesium are relatively non-toxic. In addition, magnesium is well-known for providing optimum corrosion rates under specific conditions. [..]

Abstract:
Aluminium alloys are prospective materials that can be used in wide range of applications requiring good weight-to-strength ratio, convenient corrosion resistance and others. However, low thermal stability is a problem that limits their use in applications with temperatures typically exceeding 300 °C. [..]

Abstract:
The effect of friction stir welding on the microstructure and mechanical properties of copper and Cu-30Zn brass alloy was investigated by choosing fixed rotational speed of 950 rpm with welding travel speeds of 190 and 235 mm/min for both the copper and brass alloys. Microstructural investigations showed very fine grains with some deformed grains in the stirred zone and some coarser grains in the thermo-mechanically affected zone and base metal; whereas, no obvious HAZ was detected in welds.

Abstract:
The use powder mixtures, which consists of strip-casting (Nd,Pr)-Fe-B alloy and DyH2 hydride, allows the high-coercivity magnets to be prepared. The stability of the reached high magnetic characteristics in the course of both low- and high-temperature heat treatments was shown to be related to the evolution of grain structure of the magnets.

Abstract:
Polycrystalline nickel-base superalloy MAR-M247 is used for high temperature applications requiring excellent combination of fatigue properties, creep resistance and surface stability. These superior high temperature characteristics derive from the microstructure which habitually consists of face centred cubic matrix γ and precipitate γ´ (L12 type ordered structure).
In the present work, the high temperature low cycle fatigue behaviour of cast nickel-base superalloy MAR-M247 in as received condition and in hot isostatically pressed (HIP) condition was studied. [..]

Abstract:
The powder mixtures of B2O3 added-Magnesite Waste-Quartz-Kaolinite-Alumina were mechanically activated in a planetary ball mill for 1 hours. The structural alterations and thermal behaviour of the powder mixture were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermal analysis (TG-DTA). [..]

Abstract:
In this paper was proposed to design new casting alloys on the base of the Al-Mg-Si system using Li addition to achieve precipitation strengthening effect and alloying by Ti+Zr to achieve saturation of solid solution and grain refinement effect.
The as-cast and heat treated structure of permanent mould casting of AlMg5Si2Mn containing 1.0 wt.% Li and 0.1 wt.% Ti+0.1 wt.% Zr alloys was investigated by differential scanning calorimetry, microhardness measurements, scanning and transmission electron microscopy and energy dispersive X-ray analysis. Mechanical properties of these alloys were investigated with modern automated ball indentation method. [..]

Abstract:
Ferrochromium is one of the important alloying materials used in the production of stainless and high-alloy
ferritic steels. The carbothermal reduction of chromite with graphite under argon atmosphere was studied by
differential thermal analysis up to 1350 °C and the effects of mechanical activation on the chromite structure
was investigated using of X-ray diffraction analysis and scanning electron microscopy. [..]

Abstract:
X-ray diffraction analysis and simulation of X-ray diffraction patterns are used to study the phase composition of sintered (Nd, Pr, Dy)-Fe-B magnets prepared from powder mixtures with 2 % DyH2 addition. After optimum heat treatment, which includes 1-h holding at 500 C followed by quenching in gaseous nitrogen, the magnets exhibit high magnetic properties: Br = 1.29 T, jHc = 1309 kA/m, Hk = 1220 kA/m, (BH)max = 322 kJ/m3.

Abstract:
Many activities exist in management practice, which cannot be modeled and solved by mathematical -
analytical method, but man is able successfully to solve it. For real solution of the logistic problems in
metallurgy, mainly in the field of capacity planning, operative planning and production scheduling models
creation, is most frequently applied the heuristic approach. [..]
