The aim of this paper is to observe the general behaviour of the rubber.
Introduction The rubbers are macromolecular compounds whose properties are closely related to their Chemical nature and the randomness of the distribution of the molecular chains.
We will present in this study only the results obtained for the specimen 6138_1: surface/ 50*50 mm2, thickness of the rubber/ 8 mm, material of the adherents/ aluminium alloy (fig. 3).

Abstract.
It can be stored as chemical compounds with metals (e.g.

Thus this study aims to discover the suitability of palm stearin to serve as one of the binder component in producing WC-Co part via MIM technology.
To form a WC-9Co alloy, these powders were ball-milled in ethanol media in 90 minutes.
The median particle size for this alloy, D50 was 4.35 µm and also has a broad particle size distribution; with the value of Sw is 1.63.

Only limited studies have been reported on hot workability of powder metallurgy (PM) alloys [4-6].
Representative optical microstructure of alloys after hot deformation is shown in Fig. 2.
Development of lamellar structure with different lamellae thickness is also observed in alloys.

Above 300 organic compounds (OC) with specific groups, bonding their molecules with surface atoms of steel base and coating metals by adsorption or chemisorptions forces, were examined experimentally in acid solutions and by electrodepositing of Zn, Cd, Cu, Ni, Sn, Cr and some alloys in all industrial baths.
It was a stimulus to examine the phenomenon, followed by publications in European journals describing the influence of a solution composition on the steel hydrogen fragility.
One of the most dangerous impurities in metals is hydrogen, HA by the steel melting processes causes occurrence of flakes in steel, "hydrogen illness" in Cu, porosity in Al and their alloys etc.
However, serious study of this problem, namely formulating the diffusion laws, solubility of hydrogen in metals and alloys, and consequently, deterioration of the mechanical characteristics of metallic materials began only in the 1930s in connection with the development of metallurgical science and increased demands for metal strength, durability and reliability of machines, mechanisms, and structures.
Alloying of iron and steel with 0.5 % Pd leads to 1.5 to 3 times increased penetrability for H (at identical grain size).

Alloy development of advanced ferritic steels has shown that the addition of vanadium, niobium and nitrogen can increase creep strength and chromium can provide increased oxidation resistance at higher temperatures.
The main aim was study the influence of the conditions of different tempering temperature and holding time on microstructure, substructure and mechanical properties.
These particles were identified by the selection electron diffraction analysis, as niobium carbides alloyed with boron with possible vanadium atom substitution in the crystallographic cubic NbC centered lattice.
To achieve sufficient strengthening, creep resistant steels usually contain several types of carbonitrides and intermetallic compounds in the matrix and at grain boundaries: carbonitrides including M23C6, M6C, M7C3, MX and M2X, where M denotes a metallic element, and X is carbon and/or nitrogen atoms; and intermetallic compounds such as the Fe2(Mo,W) Laves phase.
