Shade all single-phase fields. 6. Ring the three peritectic points, and one peritectoid point. c. One intermetallic compound can clearly be identified - what is its formula (atomic weights of Ti and Al are 47.90 and 26.98 respectively)? d. At what temperature does a Ti-owt% A1 alloy start to melt? e. Over what temperature range does it change from a (HCP) to B (BCC) for 20 wt% AI
