Effects of Cyclic Hydrogenation and Subsequent Solution Treatment on the Hydrogen Distribution of Ti-15V-3Al-3Sn-3Cr Alloy
碩士 === 大同大學 === 材料工程學系(所) === 98 === The as-received and pre-heat treated sheets of Ti-15V-3Al-3Cr-3Sn alloy (1000℃–30 min. and 500℃–30 min.) were processed according to the designed cyclic cathodic charging (at 50mA/cm2 for 1 hr and at 5mA/cm2 for 10 hrs) combining subsequent solution treatment to...

| Summary: | 碩士 === 大同大學 === 材料工程學系(所) === 98 === The as-received and pre-heat treated sheets of Ti-15V-3Al-3Cr-3Sn alloy (1000℃–30 min. and 500℃–30 min.) were processed according to the designed cyclic cathodic charging (at 50mA/cm2 for 1 hr and at 5mA/cm2 for 10 hrs) combining subsequent solution treatment to see the effect of various operating parameters on the microstructural change and hydrogen distribution. The variations of microstructure were investigated by employing metallographic optical microscopy (MOM) and X-Ray diffractometry (XRD) and The variations of mechanical property were investigated by employing Vickers micro-hardness test and Reciprocating wear test. The designed processing led to lattice dilatation and changes in microstructure at the near surface and a significantly enhance the hardness and strength. The α-solution treatment of Ti-15V-3Al-3Cr-3Sn alloy has a better hydrogenation ability and mechanical property. Cathodic charging at lower current density for longer operating period resulted in higher hydrogenation performance.
