"Mechanical Properties of 27Cr- White Cast Iron subjected to Sub-Zero Heat Treatments"

The study summarized that conventional thermal treatments (hardening and revising) and martensitic revision coefficients were used using saline solutions at 350 ° C. Shock resistance, hardness and erosion resistance were studied. It was found that the use of subzero coefficients increases the mechanical properties, especially erosion resistance.

“Employed Recycling Materials for the Fabrication of Smart Mortar”

The research summarizes that the smart mortar was manufactured with recycled metal powders from industrial sources to increase the electrical conductivity of cement mortar, thus increasing its use in smart applications such as magnetic shielding and solar cells. Ordinary Portland Cement (OPC) was adopted for the preparation of modified mortar control samples with recycled additives, where the sand mixing ratio for cement was 1: 3 and the water cement ratio was 0.5 W / C. The substitution rate of recycled aluminum and silicon powders was 1.5% by weight, and the casting and processing time took 7.28 days, respectively. After drying, the structural, mechanical and physical properties were examined along with electrical properties. The results showed that most properties of smart mortar have improved compared to reference cement mortar in particular, the electrical conductivity values ​​increased significantly at low frequencies of aluminum and silicon additives especially at high addition ratio (1.5)% by weight, which makes recycled materials effective in classifying this smart mortar

Cementation of Oil Well from Eco- Friendly Waste Natural Materials”

The research summarizes that the most important problems of environmental pollution were addressed through the preparation of environmentally friendly green cement consisting of natural wastes (rice husks) in different additives (0.0.25,0.5,0.75,1,1.5%). Cement The mechanical properties of the samples were measured. It was found that the rate of increase of additives from natural waste (rice husks) leads to increase the strength of pressure and hardness of cement mortar and lack of absorption of crude oil for (7 and 28) days, and after coating with a mixture of sodium silicate plus 5% % Of silicate produced from rice husk ash, so it is possible to benefit m These accumulated wastes are recycled instead of incinerated and used industrially for the purposes of oiling wells in order to obtain a clean and green environment without pollution and reduce the emission of CO2 to the atmosphere when mixing cement with water.

“Mechanical Properties and Characterization of Epoxy Composite Reinforced with Tungsten Trioxide Nanoparticle”

In this research, an epoxy compound supported by different concentrations of nanostructured trioxide nanoparticles was constructed to study the effect of these particles on three mechanical properties: hardness, shock and bending. Tests showed a significant improvement in the mechanical properties of the reinforced epoxy composite compared to the non-reinforced epoxy resin, where the hardness, bending strength and shock resistance were increased by increasing the concentration of the reinforced material from (1-3)%. The crystalline structure of the commercial material supporting the epoxy resin was also examined using X-ray diffraction.

"Study the Effect of Using Different Quenching Mediums on Erosive Wear Behavior of High Chromium White Cast Iron".

Note that this research is jointly with doctoral student Zainab Butti Aziz.

Research Summary

In this study, different hardening media were studied in the treatment of martensitic review on wear rate, microscopic composition and shock resistance of high chromium white cast iron. Two hardening agents were used at a temperature of 350 o C for different periods of time each. These two mediums are a mixture of dissolved nitrate salts and the second is a mixture of dissolved hydroxides. Both cells were found to increase erosion resistance, but nitrate mixture showed better erosion resistance, especially when treated with martensitic review at 350 ° C for 4 hours.

 Also Dr. Ali Hussein Atiwi chaired the final session of the conference
