Abstract
This research aims to determine the effect of heat treatment with quenching on titanium on hardness, microstructure and crystal structure tests. In this study, titanium was heat treated to a temperature of 900oC (austenite) with a time of 10, 15, 20 minutes and cooled using the quenching method using oil media, heat treated to a temperature of 900oC (austenite) with a time of 30, 60 minutes and 4 hours cooled with the method quenching using water media, heat treatment to a temperature of 950oC (austenite) with a time of 30,45,60 minutes and cooled by quenching method using water media. Hardness test using ASTM E18 standard. Based on the research results, it can be concluded that the most significant heat treatment can reduce the average value of raw material from 60.7 to 43.46 HRA. Testing the microstructure of titanium without heat treatment was dominated by the alpha+beta phase and it was found that the addition of elements that occurred was not significant, indicated by carbon (C) in each microstructure. In the X-Ray Defection test, the results show that there is a change in the crystal structure where titanium without heat treatment has the first peak compound, namely Titanium (Ti) with JCPDS code no. 00-005-0682, a Hexagonal crystal structure and Carbon (C) with JCPDS code no. 01-074-2329 Rhombohedral crystal structure at an angle of 20 of 40.2151o with a crystal size of 31.857 nm. while in quenching oil and water the highest peak forms Titanium (Ti) compounds with JCPDS no. 00-044-1294, Carbon (C) with JCPDS no. 01-074-2329, at an angle of 2θ of 40.23986 º at a crystal size of 4.504752042nm. forms Titanium (Ti) compounds with JCPDS no.00-044- 1294 by forming crystals namely Hexagonal, Titanium Silicon (TiSi2) with JCPDS no.00-031-1405 with crystal names namely Orthorhombic, Calcium Silicon (CaSi2) with JCPDS no. 00-001-1276 with the crystal name namely Rhombohendral, Calcium Carbonate (CaCO3) with JCPDS no.01-085-0849 with the crystal element name namely Rhombohendral, at a 2θ angle of 62.97864º at a crystal size of 25.63508976 nm.
