Structural Modification of α-Ti Based Alloy after Submission to Open Flame Thermal Shock

Ti alloys are applied extensively in several fields, particularly in the aerospace, chemical, dental and medical industries, due to their outstanding properties. Microstructure changes in commercial-purity titanium (CP-Ti) during open flame thermal shock and X-ray analysis were investigated. Water q...

description Ti alloys are applied extensively in several fields, particularly in the aerospace, chemical, dental and medical industries, due to their outstanding properties. Microstructure changes in commercial-purity titanium (CP-Ti) during open flame thermal shock and X-ray analysis were investigated. Water quenching of compact Cp-Ti has yielded martensitic-type laths and fishbone-type twinned microstructures. The microstructure of cast samples displays a martensitic structure and heat-treated samples shows a microstructure composed of α/α‘phase. Several types of phases and crystallographic lattice were detected using XRD. Samples investigated were supposed to a heating over than 1500°C and cooled in two ways: by air and by water. SEM images are taken in comparison for studying the morphology and microstructure of alloys.
