Chapter 6, Problem 6.64P

Interpretation Introduction

(a)

Interpretation:

The transition temperature of each steel needs to be determined considering energy absorbed in the ductile and brittle region by plotting results of Charpy impact test.

Concept Introduction:

The graph for steels with different manganese content needs to plotted first. The graph represents temperature distribution Vs impact energy of each steel. The transition temperature is obtained by absorbed energy in the brittle and ductile region.

Interpretation Introduction

(b)

Interpretation:

The transition temperature which provides 50 J of absorbed energy during the Charpyimpact test needs to be determined.

Concept Introduction:

The transition temperature at 50 J absorbed energy can be calculated by considering the graph of temperature Vs impact energy.
