The trapping grids are made of palladium alloys and placed after the catalyst grids, and the volatilized platinum oxide is transferred by gas flow to their surface, where platinum is reduced and subsequently diffused into the material of the trapping grid.
The aim of this work is to increase the efficiency of wire production technology for the manufacture of trapping grids.

In this regard, the aim of this work was to evaluate the effectiveness of various technologies for producing hot-extruded billets from 1580 alloy for subsequent drawing of the welding wire.
Along the cross-section of the bar, areas of accumulation of intermetallic compounds of various sizes and areas practically free of excess phases are recorded.

The aim of the investigations carried out within this study was to evaluate the cavitation erosion resistance, in correlation to the microstructure, the hardness and the residual stresses of the welded coating obtained using an impact resistant hardfacing alloy (0.57% C, 0.67% Si, 2.2% Mn, 5.77% Cr, 1.1% Mo, 0.99% V, 0.69% W), corresponding to the steel grade Fe3 (according to DIN EN 14700:2012).
Considering the chemical composition of the alloy and its prescribed applications, including thermal stability, as well as the specific appearance of the intermetallic compounds embedded in the martensitic matrix [10], one can take into consideration that they could be probably Laves (AB2) and Heusler phases (X2YZ).
This increased hardness value could be the effect of the hard intermetallic Fe-Cr-Si compounds, which are present in the martensitic matrix of the investigated material.

The selective laser melting (SLM) method has a lower cost and shorter manufacturing time than the conventional routes used in the fabrication of titanium alloys.
In this context, the aim of this work was to evaluate the microstructure and tribo-mechanical properties of Ti6Al4V alloy manufactured by SLM and the effects of subsequent stress relief heat treatments on such properties.

Mechanical alloying is known to be one of the simplest methods to produce homogeneous and fine nanostructured alloy powders on relatively large scale.
The reported material systems involve most of hard-to-sinter materials such as intermetallic compounds [6] and refractory [7-8], high-performance engineering ceramics and their composites [9-13].
In this study a production of nanostructured NiAl powder and its full densification by SPS was aimed.
Journal Title and Volume Number (to be inserted by the publisher) XRD analysis for sintered bodies (Fig. 3(a)) revealed that Ni3Al coexists as the second phase together with NiAl.

Non-conventional kind of electric discharge machining (EDM) process has been successfully used to machine titanium and its alloys.
Tempering is required only for titanium and its alloys.
Ahead of the EDS analysis in order to confirm the formation of different chemical compounds and phases X-ray Diffraction (XRD) analysis is performed.
However, due to very low score these precipitated compounds can not be seen in the XRD pattern.
