Question

___________ is defined as the ease of forming martensite.

(a) Hardness

(b) Hardenability

(c) Toughness

(d) Strength

I got this question by my college professor while I was bunking the class.

I'd like to ask this question from Hardening and Hardenability topic in chapter Heat Treatment of Engineering Material & Metallurgy

Answer 1

Correct option is (b) Hardenability

To explain I would say: Hardenability is defined as a measure or ease with which hardness is achieved. It can also be said that hardenability is the ease with which martensite is formed. Hardness, on the other hand, is the ability of a metal to resist abrasion, indentation, and scratching.
