Question

Which of the following is/are the limitations of high-temperature non-metallic materials?

(a) Lack of ductility

(b) Less resistance to thermal shock

(c) Weldability, less resistance to thermal shock, lack of ductility and formability

(d) Weldability and formability

The question was posed to me at a job interview.

Asked question is from High Temperature Materials in chapter High Temperature Corrosion of Corrosion Engineering

Answer 1

The correct option is (c) Weldability, less resistance to thermal shock, lack of ductility and formability

The explanation is: Limitations of high-temperature non-metallic materials are:

i. Lack of ductility

ii. Less resistance to thermal shock

iii. Lack of ductility

iv. Formability

v. Weldability.
