The Bureau of Mines evaluated the properties and anisotropy in properties of rolled zn-ti and zn-1.0 Wt pct cu-ti alloys containing up to 0.36 Wt pct ti. Finish rolling was at varied temperatures to total reductions as high as 92 pct. Alloy properties are very sensitive to various combinations of composition, rolling temperature, and reduction. Properly rolled zn-1.0 Cu-ti alloys are superior in strength to zn-ti alloys. Conditions are described that lead to best tensile properties. Creep resistance for zn-ti alloys decreases with increased rolling temperature when finish rolled to 92-pct total reduction, but not when finish rolled to 33- or 67-pct reduction. Creep resistance for zn-1.0 Cu-ti alloys improves with increased rolling temperature to about 480 deg f. Heavily cold- rolled zn-1.0 Cu-ti alloys have fine grain sizes and poor hardness, tensile, and creep properties, but high ductility. Thermal expansivity is markedly affected by the copper addition. Data show the anisotropy of tensile, creep, and thermal expansivity properties. Large idiomorphic crystallites of tizn15 appear in both zn-ti and zn-cu-ti alloys when more than about 0.2 pct ti is present. A new zn-cu-ti intermediate phase was also identified. Empirical equations are presented relating creep rates with major process variables.
