Question

Iron base alloys have melting point around __________

(a) 900^oC

(b) 1500^oC

(c) 1900^oC

(d) 2400^oC

I had been asked this question in a national level competition.

My enquiry is from Mechanisms of Creep & Creep Resistant Materials in portion Plastic Deformation and Creep in Crystalline Materials, Elastic, Anelastic and Viscoelastic Behaviour of Engineering Material & Metallurgy

Answer 1

The correct option is (b) 1500^oC

For explanation I would say: The most commonly used high-temperature alloys are iron base, nickel base, and cobalt base alloys. Each of these alloys possesses a high melting point temperature of around 1500^oC.
