Question

Titanium alloys (body centred cubic) ___________ heat treatment for high strength.

(a) require

(b) are made by

(c) do not require

(d) preceded

The question was posed to me by my school principal while I was bunking the class.

Enquiry is from Properties and Advantages of Titanium and it’s Alloys in portion Titanium and its Alloys of Aerospace Materials & Processes

Answer 1

The correct choice is (c) do not require

Easiest explanation: It is possible for the element titanium to exist in two crystal forms. Hexagonal close-packed structure and body – centred cubic structure. Each of these poses certain qualities and responses to heat treatment. Body centred cubic structure do not require them for strength.
