Abstract

Nowadays, the major challenge in engineering field is to improve the properties of steels in order to meet the entire engineering requirement. A better toughness, strength and ductility of steels can be achieved by applying several types of heat treatments and surface treatments. In this study, the effects of quenching and tempering of carburized low alloy steel on hardness and compression strength are investigated. There are two conditions of specimens; carburized and uncarburized low alloy steels. The carburized specimens then face different phases of heat treatments. The phases of heat treatments are carburizing and normalizing; carburizing, quenching and normalizing; and carburizing, quenching, tempering and normalizing. Then, the specimens are tested by using Rockwell hardness test and compression test. The data obtained will be analyzed and a comparison will be carried out by using statistical analysis.
