MANUFACTURING AND CHARACTERIZATION OF Ti6Al4V ALLOY BY SELECTIVE LASER MELTING
Titanium and its alloys, particularly Ti6Al4V, are widely used, especially in aerospace andmedicine due to their relatively low density, high strength, and good corrosion resistance. However,there are formidable challenges in casting, forming, and machining titanium alloys, which result infinal products that are considerably more expensive. Additiv...

THERMAL PROPERTIES OF ARMOUR STEEL
The presented investigation work investigates thermal properties of the ultra-high hardness (UHH) armour steel. Steel is distinguished with high hardness and strength. It is sold in the quenched or tempered state, because achieving planned hardness which has to be between 590 HB and 640 HB. In the frame of the investigation work the analysis of the...

EFFECT OF HEAT TREATMENT ON CHARPY IMPACT ENERGY OF MICROALLOYED HSLA STEEL NIOMOL 490K
High strength low alloy (HSLA) steels represents a group of low carbon steels that utilise small amaunts of alloying elements, such as Mo, Ti, V and Nb, to attain yield strengths in excess of 275 MPa in the as rolled condition. The main properties of HSLA steels that make them for wide variety of applications are: strength and toughn...

LCA METHOD AS AN USEFUL TOOL IN PRODUCTION ENGENEERING
The most used and established method for detecting the effects of the product on the environment is a life cycle assessment (LCA) method. LCA analyzes the effects of the product on the environment in its all five life stages: design, materials selection, manufacture, use, and ultimately its removal. At the same time LCA is an important tool wh...

DEVICE FOR IN-SITU DETECTION OF MICROSTRUCTURAL TRANSFORMATIONS
Innovative idea of the device for detecting microstructure changes, concept and construction was carried out and controlled by authors of this article in cooperation with Slovenian industry. Since the electrical resistance is one of the most structurally sensitive properties of the materials, we used its measurement to detect microstructural change...
