Synthesis of Ti3SiC2 through Pulse Discharge Sintering Powder Mixture Containing Coarse Ti

Ternary compound Ti3SiC2 was successfully synthesized by pulse discharge sintering (PDS) for Ti/Si/TiC powder mixtures with different molar ratios, where coarse Ti powder ( 0:15mm) was used. When the molar ratio of Ti:Si:TiC was selected to be 2:2:3, the content of Ti3SiC2 reached 97.8% and density reached 99.0% after sintering at 1450 C for 20min under 50MPa load. The Ti-Si liquid reaction occ...

Electric Discharge Sintering: A Mathematical Model

In this paper we mathematically model the densification of metallic powders and the sintering of ceramic powders by electric discharge. The ordinary and partial differential equations governing these processes are the same with the exception of the effective electrical conductivity. This function is a monotonically decreasing (increasing) function of temperature for the metallic (ceramic) powde...

Virtual Experiments by Pulse Heating Techniques: Cylindrical Tungsten Specimens

A bi-dimensional geometrical model was developed and numerically solved considering different cylindrical tungsten specimens, heated to temperatures above 3600 Kwith current pulses of about (500, 750, and 950) ms duration. A detailed analysis of these virtual experiments indicated large radial temperature differences in all the investigated cases. The range of validity of the long thin rod appr...

8YSZ sintering by flash sintering method and evaluation of process parameters

Flash sintering as a new sintering method for sintering of ceramic materials has been studied and effect of various parameter such as flash current density, time of flash and contact paste on properties of flash sintered 8YSZ samples has been investigated. Results showed it is possible to achieve high density in shorter time and lower temperature than conventional sintering methods. Samples cou...

Direct method for solving nonlinear two-dimensional Volterra-Fredholm integro-differential equations by block-pulse functions

In this paper, an effective numerical method is introduced for the treatment of nonlinear two-dimensional Volterra-Fredholm integro-differential equations. Here, we use the so-called two-dimensional block-pulse functions.First, the two-dimensional block-pulse operational matrix of integration and differentiation has been presented. Then, by using this matrices, the nonlinear two-dimensional Vol...
