Effect of various heat treatment processes on the impact property of a low-carbon steel was investigated.
The evolution of the impact toughness with process parameters will be mentioned and the factors which influence the stabilization of the retained austenite and impact toughness will be identified.
Results and discussion The quenching temperature is the most critical factor affecting the final microstructure and properties.
The tempering time is also a factor affecting the tempering microstructure.
It is clear that such processing parameters as quenching temperature, carbon partitioning time, tempering temperature and time determine the volume fraction and the stability of retained austenite, and thusly the mechanical property of the tested steel.

The data used to train the model encompasses factors like lattice strain, valence electron concentration ratio, mechanical stress, difference in entropy, and saturation magnetization.
This hypothesis takes into consideration factors like atomic number, valence electrons, and local magnetic moment.
This component might indicate, for instance, a mixture of factors affecting magnetic behavior.
The factors that affect the compound formation and mainly control the behavior of alloys include the lattice strain (LS), e/a ratio (EA), difference in entropy (EC), and saturation magnetization (SM).

Introduction Poly(urethane-imides) are a relatively new group of technically significant polymers with high heat resistance and excellent mechanical properties [1-3].
The immediate task of the work is to show what influence the chemical composition factors and the factors of separation and interaction of phases formed by flexible polyester and rigid imide blocks have on the glass transition (Tg) and melting (Tm) and mechanical properties in modified polymer systems.
According to the results of tests of mechanical properties, the prepared polymer compositions are close to polyimide thermoplastics of the structural type.

Introduction Carbon fiber reinforced plastic (CFRP) composites play a significant role in the automotive, marine, electronics, medical, and aerospace industries thanks to their unique, high performance, and tailorable mechanical properties [1].
The unique and tailorable properties of CFRP come from its fiber orientation, fiber and matrix properties, and relative volume of the fiber and matrix [1].
In term of cutting tool effect, tool geometry is one of the main factors in reducing thrust force.

Factors such as Uniaxial Compressive Strength, Mohs Hardness, Quartz Content, Abrasiveness, Brazilian Tensile Strength and Grain Size were considered as affecting attributes to sawability of rocks.
Sawability is affected by controlled and uncontrolled parameters.
A number of researchers studied about the relationship between the sawability and rock properties.
In the present paper, few of the stones (granites) and its properties were taken from above reference to demonstrate and to validate the above stated method.

Among high performance polymers, polyetherimide (PEI), with its high thermal and physico-mechanical properties, occupies a worthy place.
The main physico-mechanical properties of composites based on PEI with CF are given in table 2.
In general, composites with a fiber length of 3 mm show slightly higher properties; however, in the case of CF, their high content can lead to a certain degree of defectiveness of samples, which is reflected in mechanical properties.
For temperature loss of 2 % of mass, there is no clear correlation, which is apparently due to the fact that various factors can affect the onset of destruction — the presence of impurities, the heterogeneity of the composite, etc.
CF composites exhibit significantly higher mechanical properties.
