What is crater?

Crater wear is the wear at the tool chip interface in the form of depression.

We are taking place on the rake face of the tool like a crater called as crater wear.

Why its predominant for this material?
Rahul Urkude said:

Crater is formed on the surface of the tool by the action of chip particle flowing over it because of high temperature.

But tungsten is good heat dissipation, so diffusion will less and not a predominant in tungsten carbide tool. I think its answer may carbon steel tool.
Pushkar said:

Because there is good chemical affinity b/w carbon in tungsten carbide and steel tool. So diffusion occurs and due to this wear.

A is the right answer because Crater wear occurs due to more high temperature, and carbon tool steel with Stan at least temperature 290 degrees centigrade.

The answer given for this question is wrong. Crater wear occurs on rack surface predominantly at high speed and at high speeds temperature is also high which (carbon steel tools) can't withstand.

I think the Answer A is correct.
