Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
Investigation of high temperature behavior and sintering mechanism of fly ash based concretes
(Procema SA, 2014)
Four types of refractory concretes were studied at various temperatures ranging from ambient to adopted maximal 1400 degrees C. The concretes had same matrix composition: K concretes were based on corundum aggregate; B ...
High-temperature concrete binders based on fly ash
(Revista Romana de Materiale/ Romanian Journal of Materials, 2013)
High-temperature concrete binders in which fly ash, as environmentally harmful secondary raw material, is combined with masonry and refractory cement is a new option for reapplication of this coal combustion by-product. ...
Process parameters influence on microstructural properties of hypereutectic al-18wt% Si alloys obtained by rheocasting process
(Editura Stiintifica Fmr, Bucharest, 2012)
Hypereutectic Al-18wt%Si alloy was obtained by conventional and rheocasting procedure at cooling rate 0.16 +/- 0.05 degrees Cs-1. Samples of rheocasted alloy were obtained at two stirring speeds 1000 and 1500 rpm. Tests ...
Model of Probabilistic Analysis of Pile Capacity Based on the Extrapolation of Load-Settlement Curves
(Springer, New York, 2020)
This paper formulates a mathematical model using the extrapolation of load-settlement curves with a rational function for analyzing the capacity of piles obtained from the static load test (SLT). In preliminary analyses, ...
The possibility of substitution of wear resistant low chromium white iron resistant with basalt melt
(Editura Stiintifica Fmr, Bucharest, 2012)
In this study the testing results of the possibility of substituting mill lining plates for ore milling made of low chromium white iron that is resistant to wear with plates made of basalt melt are presented. Plates made ...
Characterisation of high-carbon steel surface welded layer
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
In this paper microstructural and mechanical properties of high-carbon steel surface welded layer, obtained with self-shielded flux cored wire, are presented in the case of a standard rails and crossings. The testing results ...
Determination of the effective diffusion coefficient
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The equation for drying kinetics is obtained, base on the analytical solution of the differential equation with a boundary condition in the form of the flux. This equation was initially developed by G. Efremov. In this ...
Analysis of the nominal load effects on gear load capacity using the finite-element method
(Sage Publications Ltd, London, 2010)
This research investigates the effects of the nominal load value on load distribution of simultaneously meshing gear teeth pairs, and on the involute gear load capacity. The research results presented in this article confirm ...
Future Armoured Troop Carrying Vehicles
(Defence Scientific Information Documentation Centre, Delhi, 2010)
Present-day reliance on wheeled and tracked armour personnel carriers (APCs) and infantry fighting vehicles (IFVs), may be changed in the future. Shaped charge grenades and impovised explosive devices (IEDs) represent a ...
