Composites by SHS.
Significant progress observed in SHS science results in better understanding of SHS phenomena.
The sinterable powders can be commonly obtained by deep grinding and milling of SHS products.
The mixtures were wet homogenized for 30 minutes in isopropanol using vibratory-rotary mill filled with alumina grinding media.

In the process of treatment of wollastonite in a mill there takes place, first of all, grinding of particles and their saturation with defects.
After SHS of the mixture on quartz, the sample has dielectric constant equal to 1.63.
When introducing wollastonite into the mixture quartz aluminium, the dielectric permittivity of SHS-samples decreases to 1.37-1.32.
The values ε of SHS-samples decrease to 1.17 with the increase of current in the measuring circuit.
However, after MCT during 20 minutes, the values ε of SHS-samples decrease to 1.12.

FeTi-FeB-FeCr system with low cost is adopted as the SHS reactant.
These ferroalloy powders were obtained by crushing large lumps into small pieces, and then grinding and screening.
These powders were weighted and put into a small laboratory grinding machine mixing for 60 minutes with a ratio of the powder to grinding ball 3:1.
Small zircon balls were employed for the grinding.
As the SHS reaction proceeds fast, it is probable that the SHS reaction would already complete before the molten steel contacts with the SHS products.

Thermit reaction and self-propagation high-temperature synthesis (SHS) were applied to prepare samples.
The ball-milling parameters were set up as follow：the ratio of grinding media to material was 1:1, the revolving speed was 180r/min，the ball-milling time was 8h, the balls were quenched Cr15 steel balls.
Prepare copper-matrix composite by SHS.
XRD pattern of Cu composite prepared by SHS was showed in Fig.2.
That is, SHS method can be used to prepare molybdenum particles reinforced copper-matrix composites.

Nanostructured Aluminum Matrix Composites of Al-10%TiC Obtained In Situ by the SHS Method in the Melt A.P.
Basic composition for each experiment to obtain 200 g of the fusion of composite alloy Al-10%TiC was as follows: 180 g of aluminum to create a melt in the crucible and 20 g of SHS powder mixture (SHS charge) of 16 g of titanium and 4 g of carbon.
To study the effect of addition of aluminum to the SHS charge, a powder of aluminum PA-4 (purity of 98.00%, a particle size ≤ 140 μm) in an amount of 5, 10 or 15% by weight was added to 20 g of the SHS mixture.
Prepared powder components were subjected to preliminary drying at a temperature of 100 – 110 ° C for 2 – 3 hours, then to mixing and grinding in drum ball mill for 1 hour.
Fabrication of microsections was performed on the grinding machine POLYLAB.

Through research of weld and analysis of manual SHS welding process, mechanism of copper and copper alloy’s manual SHS welding is expounded.
Mechanism of Copper and Copper Alloy’s Manual SHS Welding Copper and copper alloy’s manual SHS welding is mainly based on SHS reaction.
Since the energy for welding comes from SHS reaction, the materials for making the combustion welding rod must be capable of taking part in SHS reaction with abundant heat produced.
The metallographic microstructure is showed after the sample of setting, grinding, polishing and chemical reagent etching. 4% nitric acid alcohol solution is used for H62 in this paper.
The appearance of manual SHS welded joint was shown in Fig.2.

Products of reaction were initially crushed in a roll crusher to the grain size ca. 1 mm and than product was milled in rotary-vibratory mill for 8 hours in a isopropanol medium using WC balls as a grinding medium.
Ti3AlC2 synthesis was conducted by SHS method with use of three different precursors.
The SHS synthesis were initiated by a local ignition and conducted at 0,5 MPa of nitrogen.

Ferrous-titanium powders were obtained by crushing large lumps into small pieces, and then grinding and screening them into fin powders.
Composition of the SHS reactants is listed in Tab.1, which is referred to literature [6].
These powders were weighted and put into a small laboratory grinding machine mixing for 60 minutes with the powder to grinding ball ratio 3 to 1.
Small zircon balls were employed for the grinding.
