The tribological behaviour of Ti–30Zr, Ti–20Zr–10Nb and Ti–19Zr–10Nb–1Fe alloys was investigated using reciprocating friction and wear tests. X-ray diffraction (XRD) results indicate that Ti–30Zr, Ti–20Zr–10Nb and Ti–19Zr–10Nb–1Fe alloys are composed of hexagonal α′-martensite, orthorhombic α″-martensite and bcc β phases, respectively. Ti–30Zr alloy has the highest hardness of HV (273.1 ± 9.3), while...
The effects of annealing temperature on microstructures, phase transformation, mechanical properties, and shape memory effect of Ti–20Zr–10Nb–5Al alloy were investigated. X-ray diffraction (XRD) patterns show that the alloy is composed of single hexagonal α′-martensite phase for both as-rolled sample and sample annealed at 773 K for 30 min, while single orthorhombic α″ phase exists in the samples...
