Abstract The effect of welding parameters on the mechanical and metallurgical properties armor steel weldment was studied using gas tungsten arc process with two filler wires: carbon austenitic stainless-steel wires (AWS A5.18 ER 70S-6 AWS A5.9 307, respectively). joint configurations were mainly single V bevel grooves. Using both ER70S-6 wire ER307, for joints passed required tensile strength ...

Poor air quality is a common fact for all areas with base industry. The city of Zenica was once the metallurgical centre of Ex-Yugoslavia and is therefore highly polluted at present. Air pollution peaked in 1987 when average concentration of pollutants was extremely high (daily average concentration of SO(2) was 1800 μg m(-3)). With the beginning of the war in 1992, integral production in the s...

Laser Engineered Net Shaping (LENSTM) is a rapid-manufacturing process that involves complex thermal, mechanical, and metallurgical interactions. Due to process input parameter such as laser power , laser scanning velocity and feed rate, the effect on solidification of component to be produced must be understand. The finite element method (FEM) may be used to accurately model this process and s...

The archaeometallurgy of copper have been pioneer technologies in ancient Iran and goes back to about ten thousand years ago in Iranian Plateau [1, 2]. The Haft Tappeh Middle Elamite Site is located in Southwest Iran and have been an important city belonging to early phase of Middle Elamite period (14th century BCE) [3, 4]. Based on various metallurgical evidences found in archaeological excava...
