Perlakuan panas adalah pemanasan yang diikuti dengan penahanan dan pendinginan menggunakan media quenching. Pengerasan adalah pemanasan logam hingga suhu austenit, tahan pada suhu tersebut untuk sementara waktu dan kemudian didinginkan pada media pendinginan seperti air, minyak, udara, air garam. Untuk mengatasi perubahan sifat mekanik, perlu diberikan proses perlakuan panas. Hal ini perlu dilakukan untuk menghilangkan stress internal dan mencegah terjadinya retak atau cacat. Sifat mekanis ketangguhan adalah kemampuan material untuk menyerap energi sesaat sebelum terjadi fraktur pada struktur itu. Penelitian ini membahas tentang prediksi ketangguhan properti mekanik dengan memberikan pemanasan pada temperatur 800, 850 dan 9000C dan masing-masing specimen  diquenching dengan : air tawar, air laut dan minyak. Hasil penelitian menunjukkan bahwa terjadi peningkatan sifat ketangguhan dari efek temperatur dan media pendinginan yang digunakan. Data menunjukan pada 8000C dengan media quenching minyak nilai ketangguhan adalah 33,833 kg/cm2, serta suhu 9000C dengan quenching media air nilai ketangguhan adalah 40,8747 kg/cm2). Jadi semakin meningkat temperature perlakuan,  berpengaruh terhadap sifat ketangguhan impak bahan. Heat treatment is carried out by heating followed by anchoring and using quenching medium as cooling. Hardening is metal heating to austenite temperature, hold it at a temporary temperature and then cooled to cooling media such as water, oil, air, brine. To overcome the change of mechanical properties, need to be given process of heat treatment. This is to remove internal stress and prevent the occurrence of cracks or defects. The mechanical properties of toughness are the ability of the material to absorb energy without fracturing the structure. This study discusses the prediction of toughness of mechanical properties by heating at temperatures of 800, 850 and 9000C and each specimen quenching with: freshwater, seawater and oil. The results showed that there was an increase in the toughness properties of the temperature effect and the cooling medium used. The data show on 8000C with medium quenching oil the toughness value is 33.833 kg/cm2, and the temperature of 9000C with quenching medium water toughness value is 40.8747 kg/cm2). So the increasing of treatment temperature has influence to the material toughness

TiNbSn alloys have been extensively researched due to several properties they exhibit, including high mechanical strength, low elastic modulus, superelasticity, shape memory effect, biocompatibility. The present study evaluated the cryogenic heat treatment in the Ti35NbxSn alloys (x = 0.0; 2.5; 5.0; 7.5). The alloys were arc melted, cold formed and quenched in both water and liquid nitrogen at-198° C. The Ti35Nb2.5Sn alloy was also aged after exposed to both quenching medium. Microstructure and microhardness analyses were performed. Cryogenic treatment was not enough for transformation of primary β phase into martensitic α” in alloys containing 5 and 7.5% Sn. Cryogenic treatment provided β to α” transformation in alloys containing 0 and 2.5% Sn. The Sn-free alloy was more likely to α" transformation in both quenching medium. The alloys microhardness increased with decrease of both quenching temperature and Sn content. The increase of α" is also related to the increase of the alloy microhardness after aging.
