ZTP10 powder: Fatigue resistant and ductile
Due to good high temperature stability, high corrosion resistance and specific strength, Ti64 is one of the most widely used titanium alloys, accounting for more than 50% of the titanium usage worldwide. Ti64 was used in industry since 1950s and has been widely used in aerospace, biomedical and automotive fields. However, the relatively low wear resistance, low heat resistance and low fatigue endurance of Ti64 are the major drawbacks, limiting its widespread application in industrial fields especially in additive manufacturing.
A designed powder of Titanium matrix nano-composite (nTMC) for additive manufacturing, ZTP10 belongs to ZTi-Powder® family and it was created by Z3DLAB to overcome the deficiencies of Ti6Al4V (Ti64) alloy at room and high temperature. The Fatigue endurance of additively manufactured ZTP10 powder is 40% higher than Ti64 manufactured via powder bed fusion technology (PBF). Experiments were conducted at room and high temperatures in order to investigate the mechanical behavior of ZTP10 and to create a processing map of the material. The results showed that ZTP10 has a very stable behavior at high temperatures until 850°C.
Thermal resistance is also considered as an important factor for material selection in critical parts mainly in aerospace and automotive. The thermal oxidation of Ti64 generally starts around 270 °C resulting in a color change from gray (natural color of Ti64) to black color depending on temperature. This drawback is due to the low thermal resistance of Ti64. However, ZTP10 was designed to resist high temperature oxidations (see picture above).
