Explanation:

PROPERTIES OF HIGH.PURITY IRON

By Harold E. Cleaves and John M. Hiegel

ABSTRACT

Results are recorded of new determinations of the workability, microstructure,

density, and the thermal, mechanical, electrical, and magnetic properties of

high-purity iron, in which the maximum amount of an individual impurity was 0.004 percent and the total of impurities in any specimen was 0.01 percent or less.

I. INTRODUCTION

Ferrous materials, from cast iron to complex alloy steels, are essen-

tially impure irons, and their properties are the properties of the

basic material, iron, modified by the presence of alloying elements

and impurities or by factors such as heat treatment and mechanical

work. Throughout the history of fe1'l'ous metallurgy, knowledge of

the properties of "pure iron" has been regarded as essential to an

understanding of the effects of different factors on the properties of

known metals and to indicate the possibilities and limitations of new

alloys or combinations. The need for accurate information is greater

today than ever before to meet the demands for greater reliability

and for improved or new properties in ferrous materials.

• However, the term iron is used for different materials which contain a high percentage of iron in elemental form. These materials are categorized as (i) pure iron, (ii) wrought iron, (iii) cast iron, (iv) pig iron, and (v) direct reduced iron.
