Pengembangan Baja Paduan Tahan Peluru Melalui Proses Hot-Forging Terhadap Morfologi Dan Sifat Mekanik

Laterite steel is that has a nickel content of up to 2%. The can produce with superior properties such as: high strength, corrosion resistance, and good weldability properties. With the nature laterite needed in main tool indonesian national tantara weapon system. To find out performance damage bulletproof materials, then conducted research on this as tough armour material by conducting form mechanical testing (Hardness, Impact) microstructures (Metalography). Samples are prepared accordance ASTM standardization. Based results hardness test, average values F T samples were 663.9 HVN 170.7 HVN. Material qualifies ballistic resistant (armour) because obtained classification withstand bullet penetration well. Then impact test value 9 joules 148 joules. For samples, type fault granular fracture sample tenacious fracture. As result metallographics, corrected phase upper bainite matrix martensite generally shaped like fine needle. formed dominated ferrite soft well perlite quite hard strong
