Abstract:
The article deals with the thermodynamics of the process in the ore-thermal processing of copper smelting slag, the experimental study of ore-smelting processing of copper smelting slag, and the development of a mathematical model for obtaining iron-containing alloys from copper slag, development of a technological scheme for obtaining iron-containing alloys from copper slag-information on the application and approbation of the technology in the production of the results.The assessment of the possible direction of the carbothermic reactions that take place between the oxidised compounds in the slag and the carbon was carried out by changing the thermodynamic values of the system. Thermodynamic analyses were performed, taking into account the temperature dependence of the isobaric-isothermal potentials (Gibbs free energy).. [..]

Abstract:
In the conventional powder metallurgy (PM) process route, finished components are produced from metallic powder materials by pressing at room temperature followed by pressureless sintering in a furnace. This simple method for fast and cost-effective processing is not suitable for γ-based titanium aluminides. [..]

Abstract:
This article presents the history of tin metallurgy in Rwanda, its current state, and future development prospects on the example of the Luna Smelter production plant, located in Kigali. The authors of the article pay special attention to the issues of successful restoration of production, which was stopped in 1994, shortly before the Tutsi Genocide, the impact on the labor market in Kigali, the creation of new commercial and economic ties, as well as the improvement of production lines and the optimization of technological parameters of smelting and refining..

Abstract:
We follow an alnico alloy sample to non destructive testing using X-ray radiography. X-ray Computed Tomography (CT), also widely known as MicroCT, is a proven method for not only checking the structural integrity of casting parts - for example for porosity - but also for checking a dimensional accuracy.

Abstract:
The main objective is to model the plastic behavior of the three aluminum alloys 1050, 2024 and 7075.In the first part, using the experimental results of uniaxial tensile tests for each alloy and in the three main directions, and using a strategy of identifying the parameters of each work hardening model studied, Hollomon, Swift and Voce, we have created an empirical database of 1050, 2024 and 7075 aluminum series alloys.In the second part, one established the curves of uniaxial tensile curve by using the work hardening laws and the experimental parameters obtained in the first part. The comparison with the experimental data shows that the plastic behavior model can successfully describe with the use of appropriate workhardening law for each alloy.. [..]
