The　use　of　laser　directed　melting　deposited　(LDMD)　Ti-6Al-4V　alloys　is　mostly　seen　in　the　field　of　aeronautics.　Clearly　demonstrating　the　deformation　method　as　a　function　of　application　conditions　is　of　utmost　importance.　The　objective　of　this　study　was　to　investigate　the　mechanical　characteristics　and　dynamic　substructure　formation　of　LDMD　(Ti-6Al-4V)　alloys　at　different　temperatures,　namely　23,　650,　and　200　degrees　C.　This　review　study　examines　the　mechanisms　of　deformation　at　both　low　and　high　temperatures.　Tensile　testing　was　conducted　in　situ　using　scanning　electron　microscopy　to　examine　the　onset　and　progression　of　fractures.　At　temperatures　of　23　and　650　degrees　C,　the　experimental　findings　demonstrated　a　strength　decrease　and　elongation　increase　at　the　climbed　temperature.　At　a　temperature　of　200　degrees　C,　the　microstructure　of　the　sample　was　composed　of　inclined　alpha-plates　oriented　in　the　direction　of　construction　and　columnar　beta-grains　with　zigzag　grain　borders,　according　to　the　results.　Consequently,　when　the　temperature　was　increased　to　200　degrees　C,　a　greater　degree　of　elongation　and　a　decrease　in　cross-sectional　area　were　observed　compared　to　the　conditions　at　ambient　temperature.
