“…5, the K values of pure Al [26], pure Zn [26], pure Mg [27], studied alloy and some Al alloys [23][24][25][28][29][30][31] decrease with increasing temperature, and the measured lines of K variations with temperature for the Al--5.5Zn-2.5Mg alloy are fairly below the line of K variation with temperature for pure Al [26], pure Mg [27], Al-1Mg alloy [28], Al-5Zn [29], Al-0.7Mg-0.4Si [30], Al-6.1Zn-2.3Mg-1.9Cu [23], and Al-5.6Zn-2.5Mg--1.6Cu [24]. Also, the K values obtained for the studied alloy (Table 2) were slightly higher than those obtained for pure Zn [26], 7075/AlN composite [31], and Al-3.25Zn-1.9Mg-1.8Cu alloy [25]. In the case of pure Al and pure Zn, there were relatively fewer impurities, such as solute atoms of Mg and Zn in α-Al matrix.…”

In this work, the thermal conductivity, enthalpy of fusion, specific heat capacity, and thermal diffusivity of the Al-5.5Zn-2.5Mg (wt.%) ternary alloy have been investigated. Thermal conductivity of as-cast Al-5.5Zn-2.5Mg alloy was measured using comparison cut bar method in the temperature range of 323-723 K. With the increase of temperature, thermal conductivity decreased gradually in as-cast Al-5.5Zn-2.5Mg alloy. The thermal temperature coefficient was calculated from the respective graph. The enthalpy of fusion and the specific heat capacity during the transformation were also determined. Thermal diffusivity changes were calculated as a function of temperature through the obtained thermal data. It was observed that thermal diffusivity values decreased with increasing temperature.

“…Due to their excellent castability, where silicon plays a significant role, especially having high thermal characteristics that increase fluidity, Al-Si casting alloys are frequently utilized to create engine parts. [1][2][3]. Otherwise, casting characteristics of AI-Si alloys requires careful melting, degasifying, and pouring.…”

One of the principal attributes of the aluminum-silicon alloys is their excellent fluidity, or the ability to fill a mold cavity. Fluidity is a complex characteristic that is influenced by surface tension, viscosity, alloy freezing range, melt, cleanliness, superheat, and solidification conditions. Chemical modifiers are generally considered to be detrimental to fluidity despite the fact that all the chemical modifiers commonly in use decrease surface tension. This investigation has been carried out to study the influence of pouring temperature of aluminum piston alloy on casting fluidity and microstructure defects. A strip type of fluidity testing mould was used in this study, and optical microscope to find microstructure defects. The results showed that higher the pouring temperature greater the casting fluidity. Otherwise, the overheating caused porosity, solidification shrinkage, and dross formation into the microstructure of the alloys melted at temperature higher than 760 C°.

Through this research, polymeric composites were prepared from Addition of epoxy resin with iron filings in certain weight ratios (0.5%,1%,1.5%,2%,2.5%,3%,4%,4.5%,5%) as a reinforcement material. The comparison was made between polymeric composites Before and after the cementing process , After a series of experiments, it was found that the best weight percentage was (1%),This addition was done at different temperatures (8,25,55) °C, The results when compared before and after the reinforcement process for the composites showed that the thermal conductivity the thermal conductivity increased after the strengthening process, for the mechanical properties, Impact test, Hardness and compressive strength, they increased at 25°C and increased at processing temperatures(8.55)°C.
