The figure shows the binary phase diagram titanium-nickel (TI-NI). The atomic radii of Ti and Niane 0.140 nm and 0.135 nm, respectively. 1800 1670°C 1600 L 1455°C 1400 1380°C 1310°C 7304 Temperature °C 1200 TINI (Ni) 1000 P04C (ATI) P12 882"C TiNi 800 785°C Hati) TiaNi 600 0 TI 10 20 30 40 50 60 70 80 90 Weight Percent Nickel 100 Ni Question 12 What is the maximum solubility of Niin solid tanium Less than 1 wt. About Gwt. About 12 w About 28 wts Question 13 Considering an TI-Nially with 20 wt.% NL Which defects contribute to the hardness of this aloy at 800 "CZ Only phase boundaries Only soluta atoms Both phase boundaries and solute atoms Neither phase boundaries, nor soluta atoms Question 14 Considering an TI-Ni alloy with 20 wt.% NL. At 950 "C. Ni atoms are to be found... in the mot on interstitial sites in (TI) on regular lattice sites in (TI) on regular lattice sites in TIN Question 15 Considering an TI-Nialloy with 86 wt.% Ni which is slowly cooled from 1500 C to 600 "C? Which statement about the phases present at GOD "C is correct? Only one phase, the eutectic phase with exactly 86 wt% NI, is present at 600 °C Two phases, (NI) with 88 wt% Ni and TINI 3, are present at 600 °C Two phases, (N) with 93 wt. S. Ni and TINiz, are present at 500 °C Three phases. (NI) with 3 wt.% NL TINiz and the cutectic phase with 85 wt% Ni, are present at 600 °C Question 16 Considering an TI-Ni alloy with 90 wt.% Ni which is slowly cooled from 1500 C to 600C? How does the microstructure look like at 600 "C? (Ni) and TINiz form a lamellar structure throughout (NI) and TN form a lamellar structure, additionally proeutectic (N) is found (Ni) and TINiz form a lamellar structure, additionally protectic TINiz is found TINiz particles are distributed randomly within Ngrains
