THE EFFECT OF LEAD ON MICRO-CRACK INITIATION AND PROPAGATION IN ALLOY STEELS. PART B: A FRACTOGRAPHIC STUDY OF LEADED 4145 STEEL TESTED AT ELEVATED TEMPERATURES

Abstract

A visual analysis of the fractured surfaces from both leaded and non- leaded tensile specimens was performed at various ultimate strength levels from 120 KSl to 240 KSl and the fractures were classified into five types.
